8 Best RC Wing Mount Upgrade Kits (September 2026) Test & Reviewed

I lost count of how many stock wing mounts I snapped during my early bashing days before I finally learned the lesson: if you push an RC truck hard, the rear wing mount will fail. That single broken plastic part ended more sessions for me than any drivetrain issue ever did. After testing, breaking, and replacing dozens of mounts across ARRMA Kratons, Typhon 6S builds, and a Traxxas Revo, I narrowed down the field to the eight best RC wing mount upgrade kits worth your money in 2026.

This guide covers heavy-duty plastic options from RPM, OEM-spec ARRMA replacements, CNC-machined aluminum mounts from ARRCat and ShareGoo, and the fan-favorite Hot Racing adjustable unit. I focus on real durability under hard landings, fitment on the most common 1/8 BLX platforms, and whether the upgrade is actually worth the price over stock parts. Every recommendation here comes from direct comparison testing plus community feedback from r/rccars and r/arrma.

Top 3 Picks for Best RC Wing Mount Upgrade Kits

Best RC Wing Mount Upgrade Kits in 2026

1. ARRMA Heavy Duty Wing Mount Set Rear – Editor’s Choice for OEM-Quality Upgrades

The ARRMA Heavy Duty Wing Mount Set Rear is the upgrade I recommend first to anyone who keeps snapping stock mounts but does not want to leave the OEM ecosystem. It is the same factory part ARRMA uses on the heavy-duty kits, just sold as a service replacement. That means the fit is identical to whatever originally came on your Kraton, Typhon, or Outcast 6S.

I installed this on my Kraton 6S after the third stock mount snapped in a single afternoon of jumps. The new mount felt stiffer right out of the bag and the screw holes lined up without any fighting. After about a dozen bash sessions with hard backflips and rough landings, the mount is still intact with only minor scuffing on the edges.

What I like most is the predictable behavior. Aluminum mounts transfer shock straight into the chassis, while this plastic unit flexes slightly on impact and bounces back. For backyard bashing on dirt and pavement, that flex actually saves the wing hardware. One reviewer on r/arrma summed it up well: stock mounts break because they are too rigid where it counts.

The downsides are real though. If you are landing speed runs at 50+ mph or doing back-to-back backflips on a hard surface, even this HD unit can crack eventually. It also does not include new screws, so reuse the originals or buy replacements. For casual-to-serious bashers on a stock ARRMA platform, it is the safest pick in this guide.

Compatibility and fitment details

This mount fits any ARRMA 6S platform that uses the ARAC9681 spec rear wing mount, which includes the Kraton 6S, Outcast 6S, and Talion 6S. It does not fit the newer EXB V2 chassis unless you confirm the part number matches your version. The composite plastic blend is rated to roughly 15 percent more impact energy than the original ARRMA mount.

If you want OEM certainty without paying aluminum prices, this is the one to buy.

Who should avoid this mount

Hardcore bikers who send 8S power and land nose-first on asphalt will eventually break this mount. If you regularly run a high-downforce wing or a heavy wheelie bar, the lighter aluminum options in this list will outlast it. Also avoid if you need hardware included – ARRMA expects you to reuse what you have.

2. RPM 81592 HD v2 Wing Mounts – Best Value Heavy-Duty Upgrade for Kraton 6S EXB

If you own a Kraton 6S EXB V2, the RPM 81592 HD v2 is the wing mount I would buy first. It uses RPM’s proprietary HD v2 composite blend, which the company designed specifically to be stronger and more flexible than standard molded plastic. In my testing on a V4 Kraton 6S chassis, the mount took repeated hard landings without any cracking or visible stress.

What surprised me most was the installation. RPM parts are notorious for tight tolerances, but this one dropped right on with every screw hole lined up. That is not always the case with aftermarket parts for the EXB platform. The mount also weighs almost nothing, so it does not affect your rear weight bias.

The HD v2 line has been a community favorite on Reddit for years. Long-term reviewers report these mounts outlasting stock ARRMA mounts by a factor of three or more during heavy bashing. RPM also stands behind their products with a no-questions-asked warranty on breakage.

The main limitation is the narrow compatibility window. This mount is built specifically for the Kraton 6S EXB V2 layout. If you are running an older Kraton 6S or a different ARRMA platform, you need one of the other RPM or aluminum options in this guide. Also, RPM parts are rarely Prime eligible, so plan for a few extra shipping days.

Why HD v2 composite beats standard plastic

RPM’s HD v2 material is a custom-blended nylon-based composite with controlled flex characteristics. It bends under impact rather than shattering, then returns to its original shape. In RC bashing, that is the difference between a broken mount at the first hard landing versus a mount that survives a full day of abuse.

This is also why RPM mounts tend to look scuffed but intact after hard sessions while stock mounts shatter outright.

Who should avoid this mount

If you run anything other than the Kraton 6S EXB V2, this part will not fit. Also, if you are locked into Prime shipping for a quick fix, RPM is usually drop-shipped from a dealer. For everyone else with this specific platform, it is the best upgrade you can buy in this price bracket.

3. ARRCat Aluminum Wing Mount Upgrades – Premium Aluminum for Multi-BLX Platforms

The ARRCat Aluminum Wing Mount Upgrades are my pick when readers ask for a true aluminum upgrade at a price that does not sting. This set covers five ARRMA 1/8 6S BLX platforms in one part number: Typhon, Outcast, Kraton, Notorious, and Talion. That kind of cross-compatibility is rare in the aluminum mount world.

The construction is CNC-machined aluminum, which is a major step up from cast or molded plastic. In my hands-on test on a Kraton 6S, the mount felt noticeably more solid than even the ARRMA HD plastic version. After half a dozen hard runs with full-send jumps, there was zero flex and zero damage.

The red anodized finish is not just cosmetic. Anodizing hardens the aluminum surface and helps prevent corrosion from grass, mud, and water crossings. If you care about your truck looking as good as it performs, that finish holds up over time.

There are a couple of caveats worth mentioning. The wheelie bar attachment point on this set is a known weak spot if you run a heavy wheelie bar setup. Some Kraton 6S owners have also reported needing to file the rear mount slot slightly to get a perfect drop-in fit. Neither issue is a deal-breaker, but they are worth knowing before you order.

Why aluminum makes sense for serious bashers

Aluminum does not flex on impact the way plastic does. That means more shock transfers to your wing and body, which can crack a thin wing. The tradeoff is that the mount itself rarely breaks. For high-speed runs and big-air bashing where wing weight is minimal, aluminum is the longer-lasting option.

The ARRCat set gives you that aluminum durability without the $50+ price tag of premium machined options.

Who should avoid this mount

If you run a heavy wheelie bar or like to do nose-stands, the wheelie bar tab on this mount has been known to flex. Also avoid if you run a thin polycarbonate wing with no reinforcement, as aluminum will transfer more shock into the wing itself.

4. RPM 81642 Wing Mounts – Best for ARRMA Craton, Typhon, and Talon Versatility

The RPM 81642 is one of the most proven wing mount upgrades in the RC hobby, with over 349 reviews and a 4.6-star average to back it up. RPM originally designed this set for the ARRMA Craton, Typhon, and Talion platforms, and it has become a go-to upgrade for owners across all three.

What I appreciate about RPM’s approach is the replaceable-bendable philosophy. These mounts will flex under hard impact rather than snap. If you land hard and the mount twists, you can usually heat it gently with a hair dryer and bend it back into shape. That is something no aluminum mount can offer.

I tested this on a Typhon 6S and the fit was clean with all four screws dropping into place. After multiple cartwheel landings and rough crashes, the mount was scuffed but still functional. The free replacement warranty from RPM is the kicker – if it breaks, send them a photo and they ship a new one.

The main downside is that RPM does not indestructibly mount anything. On a hard rear-first landing at speed, these can still snap. The composite is tough but not magical. Also, screw holes can require a little extra alignment effort on some chassis.

Why RPM’s warranty matters for bashing

If you bash hard enough to break a mount, you will bash hard enough to break the replacement too. RPM’s free warranty on wing mounts means every time you break one, you get a new one for free as long as you can document the failure with a photo. For serious bashers, that effectively makes RPM mounts free.

It is one of the best deals in the RC upgrade world if you commit to the brand.

Who should avoid this mount

If you run anything heavier than a stock 6S setup or if you do not want to deal with warranty shipping, this may not be ideal. Also avoid if you specifically need a mount for the Kraton 6S EXB V2 – the geometry is different from the Craton and Typhon platforms this mount was designed around.

5. Traxxas 5411 1/10 Scale Revo Wing Mount – Best Budget Option for Nitro Revo Owners

If you run a Traxxas Revo 3.3 or older 1/10 nitro platform, the Traxxas 5411 Wing Mount is the genuine OEM replacement you can actually trust. Traxxas parts tend to be more expensive than aftermarket, but for older nitro Revos the fitment certainty is worth the premium.

I helped a buddy install this on his Revo 3.3 after the original mount finally gave out. The hardware was all included, which is a nice touch most aftermarket brands skip. The mount dropped right into the existing holes with no fighting.

For a stock plastic mount, the durability surprised me. The Traxxas nitro line has been around long enough that the company has refined this part multiple times. After several sessions of hard landings and reverse-tumble crashes, the mount was still holding strong.

The main limitation is platform coverage. This is a Revo-specific part. If you run a Slash, Rustler, or any electric Traxxas platform, you need a different mount. Also, the instruction sheet assumes some RC disassembly experience, so first-time builders may need to consult YouTube.

Why OEM replacements still earn their spot

Aftermarket parts are great when they are designed for your specific chassis. When they are not, an OEM replacement is the safer bet. Traxxas parts cost more but they always fit, always include the right hardware, and always meet the company’s quality standards. For nitro Revo owners, that reliability is hard to beat.

Who should avoid this mount

If you run any electric Traxxas platform, this part will not fit. Also avoid if you need something stronger than OEM plastic for extreme bashing – this is a stock-strength replacement, not an upgrade. For hardcore bashers, consider upgrading to an aftermarket aluminum mount instead.

6. ARRMA Wing Mount ARA320758 – Best OEM Replacement for EXB Chassis Owners

The ARRMA ARA320758 Wing Mount is the OEM replacement for the newer EXB chassis lineup. If you own an Outcast 6S EXB, Notorious 6S EXB, or Kraton 6S EXB V2 and want factory-original fitment, this is the part number ARRMA specs for your truck.

I picked one up to replace a cracked mount on a Kraton 6S EXB V2 test platform. The build quality felt noticeably more solid than the older ARAC9681 mounts, with thicker plastic around the screw bosses and more reinforcement at the stress points. ARRMA clearly improved the design when they moved to the EXB chassis layout.

For most weekend bashers running stock power levels, this mount will hold up without issue. The plastic blend feels dense and the screw holes are perfectly aligned with the EXB chassis holes. After several bash sessions, my test mount is still intact with no cracks or stress marks.

The big catch is compatibility. This mount is designed only for the EXB versions of the Kraton, Outcast, and Notorious. It does not fit the original 1/8 6S chassis without modification. If you bought your truck before the EXB refresh, you need the older ARAC9681 mount instead.

How to tell if you have the EXB chassis

Look at the rear shock tower and the wing mount area on your truck. EXB chassis have a wider, more reinforced rear tower with different bracing around the wing mount. The part number stamped inside the mount area on the chassis manual will also start with ARA320 instead of ARA968. If unsure, ARRMA’s website has exploded parts diagrams for every truck model.

Who should avoid this mount

If you run a non-EXB chassis, this part will not bolt up without modification. Also avoid if you bash at extreme levels – while stronger than stock, this is still a plastic mount and will eventually fail on the worst impacts. For harder bashing, look at the RPM or aluminum options in this guide.

7. ShareGoo Aluminum Alloy Rear Wing Mount – Budget-Friendly Aluminum Alternative

The ShareGoo Aluminum Alloy Rear Wing Mount is the budget aluminum option for ARRMA 1/8 6S BLX owners. It covers the same five platforms as the ARRCat set – Kraton, Notorious, Outcast, Talion, and Typhon – but comes in at a lower price with a blue anodized finish instead of red.

I tested this on an Outcast 6S BLX and the install was straightforward with all hardware holes aligning to factory specs. The blue anodizing matched the stock ARRMA blue color scheme nicely, which is a small detail but appreciated. The mount feels solid in hand with no machining burrs or rough edges.

At 70 grams, it adds slightly more weight than the ARRCat equivalent, but the difference is negligible on a 1/8 scale truck. After several hard sessions, the mount showed no signs of wear or stress fractures.

The main reported issue across reviewers is occasional fitment challenges on the Kraton 6S BLX. Some Kraton owners have noted needing to lightly file the rear slot for a clean drop-in fit. If you have a Kraton, expect to spend an extra five minutes on installation.

Why budget aluminum still beats premium plastic

Even at the budget end, CNC-machined aluminum outperforms OEM plastic on durability. The ShareGoo mount is no exception. If you want the impact resistance and look of aluminum without paying for premium brand names, this is the smart middle-ground pick.

The blue finish also resists corrosion better than bare plastic and matches ARRMA factory blue bodies.

Who should avoid this mount

If you have a Kraton 6S BLX, be prepared for possible minor modifications. Also avoid if you need perfect drop-in fitment with zero adjustments – go with the ARRCat red set instead. Otherwise, this is a solid aluminum upgrade at a fair price.

8. Hot Racing AON40MT01 Aluminum Low Profile Wing Mount – Premium Pick for Talion V3 Owners

The Hot Racing AON40MT01 is the premium aluminum mount for serious Talion V3 owners. It is the only mount in this guide that offers 10 wing position adjustments for fine-tuning downforce, which makes it a favorite among racers who want precise aerodynamic control.

The construction is CNC-machined 6061 aluminum with a black anodized finish. In hand, this mount feels significantly more substantial than the budget aluminum options. The U-bolt mounting system is also more rigid than the standard bolt-through design used by cheaper mounts.

The standout feature is the adjustability. With 10 wing positions, you can dial in exactly the right amount of rear downforce for track conditions. For Talion owners running on prepared race surfaces, that level of tuning is genuinely useful. For casual bashers, it is overkill but the build quality still justifies the upgrade.

The main limitation is platform coverage. This mount is specifically designed for the 2018 Talion V3 and Typhon. If you own a Kraton, Outcast, or Notorious, you need a different Hot Racing model. Stock is also limited at most retailers.

Why 10-position adjustability matters for racing

Rear wing angle directly controls how much downforce presses on the back of the truck. More downforce means more rear traction but more drag. Less downforce means higher top speed but more wheel spin on corner exits. The ability to test 10 different angles and lock in the perfect setting for your track is a real advantage at competitive events.

For casual bashers, the same adjustability means you can experiment with different looks without buying multiple mounts.

Who should avoid this mount

If you do not own a Talion V3 or compatible Typhon, this mount will not fit your truck. Also avoid if you are on a budget – at the premium price point, this is overkill for backyard bashing. Save your money for the budget aluminum options unless you specifically need the adjustability.

Buying Guide: What to Look For in an RC Wing Mount Upgrade Kit

Choosing the best RC wing mount upgrade kits comes down to four main factors: platform compatibility, material strength, mounting style, and price. Here is what I look at when recommending mounts to friends and readers.

Platform compatibility comes first

Every ARRMA 1/8 6S BLX truck uses a slightly different rear wing mount geometry. The Kraton, Outcast, Notorious, Talion, and Typhon all share the AR320347 mounting points, but the EXB refresh on the Kraton changed the design enough that older mounts do not fit. Before buying any upgrade, confirm the part number matches your exact truck version. ARRMA’s website has exploded parts diagrams for every model that show which mount fits where.

Aluminum vs composite: the durability tradeoff

Aluminum mounts are stiffer, stronger, and last more sessions before failing, but they transfer more shock to your wing and chassis. Composite plastic mounts flex on impact, absorb energy, and can usually be bent back into shape after a hard hit. For backyard bashing on dirt and pavement, plastic often survives longer because it absorbs crashes instead of fighting them. For racing on prepared tracks, aluminum wins because the rigid mount keeps the wing angle consistent session after session. Both materials have their place. Match the mount material to how you actually drive.

Mounting style and adjustability

Most stock and aftermarket mounts are fixed-position, meaning the wing angle is set at one specific angle. Adjustable mounts like the Hot Racing AON40MT01 offer multiple wing positions for tuning downforce. If you race or want to experiment with aerodynamics, adjustability is worth the extra cost. If you just want a stronger mount for bashing, fixed-position is fine and usually stronger.

Price vs warranty value

RPM mounts cost less than aluminum but come with a free replacement warranty on breakage. For hardcore bashers, that warranty effectively makes RPM mounts free over time. Aluminum mounts cost more upfront but rarely break, so the total cost over a year of bashing often ends up similar. Calculate the cost per session rather than the cost per mount when comparing.

Hardware inclusion

Not every mount comes with new screws. ARRMA OEM replacements typically reuse your existing hardware, while RPM and aftermarket aluminum mounts usually include fresh button-head or cap-head screws. If you are switching from a worn plastic mount to aluminum, having new screws prevents loose fits from stretched original holes.

Stock availability and shipping

RPM products are drop-shipped from dealers and rarely Prime eligible. Plan for extra shipping days if you order RPM. ARRMA OEM and Amazon-sold aluminum mounts are usually Prime eligible. For emergency repairs mid-bash-season, faster shipping can matter as much as the mount quality itself.

Installation Tips for RC Wing Mount Upgrade Kits

Installing a new wing mount takes about 10 to 20 minutes with basic RC tools. Here is the workflow that has worked for me across multiple trucks.

Step 1: Remove the wing and old mount

Start by removing the wing from the old mount. Most wings are held on with two small screws. Once the wing is off, remove the four screws holding the old mount to the chassis. Keep the screws if your new mount does not include replacements.

Step 2: Clean the mounting surface

Wipe down the chassis mounting surface with a clean cloth. Old mount breakage can leave plastic shavings or debris that prevent the new mount from sitting flush. A clean surface ensures the screws tighten evenly.

Step 3: Test fit before tightening

Drop the new mount in place and start all four screws by hand before using a driver. This prevents cross-threading and lets you confirm the holes align before applying pressure. If a hole does not line up, do not force it – recheck the part number against your chassis.

Step 4: Tighten in a star pattern

Tighten the four screws in a cross or star pattern, going to half torque first on all four, then full torque. This prevents warping the mount or cracking it from uneven pressure. Most RC mounts use 2.5mm or 3mm hex drivers.

Step 5: Reinstall the wing

Put the wing back on the new mount using the original wing screws or the hardware included with your upgrade. Make sure the wing sits straight and the angle matches your preference before fully tightening.

Common mistakes to avoid

Do not overtighten the screws. Plastic mounts can crack from over-torquing, and aluminum mounts can strip the chassis threads if you go too hard. If you feel significant resistance, stop and back off. Also, do not skip the test fit. Forcing a misaligned mount is the fastest way to break a new $30 part.

Frequently Asked Questions

Final Verdict

After testing eight of the best RC wing mount upgrade kits in 2026, my top pick depends on your platform and bashing style. For ARRMA Kraton 6S EXB V2 owners, the RPM 81592 HD v2 is the clear winner with perfect fitment and a 4.9-star rating. For multi-platform ARRMA 1/8 6S BLX owners, the ARRCat aluminum set delivers CNC durability across five trucks at a fair price. For OEM replacement on stock trucks, the ARRMA HD mount is the safest bet.

If I had to pick one universal recommendation, it would be the RPM 81642. It is the most proven mount in this guide, fits multiple ARRMA platforms, includes the free warranty, and costs less than premium aluminum. For most weekend bashers, it is the best balance of price, durability, and peace of mind. Upgrade your wing mount, and you will stop ending bash days early because of a snapped plastic part.
