Overview
The RPM Rear A-arms for the Traxxas Slash 2WD represent a significant upgrade over the stock suspension components found on factory models. RPM engineered these arms specifically for the Slash 2WD platform, abandoning the multi-platform compromise approach that manufacturers traditionally use. Whether you're a serious racer pushing your brushless RC short course truck to its limits on the track or a weekend basher looking for enhanced durability and performance, these purpose-built rear A-arms deliver the reinforcement and rigidity your Slash needs to handle serious abuse. Unlike generic suspension upgrades, RPM designed every aspect of these A-arms around what the Slash demands, removing unnecessary features whilst adding critical strength where it matters most.
If you're running a Traxxas Slash 2WD RC truck in the UK and want to tighten up the rear end whilst maintaining stock geometry and predictable handling characteristics, this is the upgrade you've been looking for. RPM has invested serious engineering effort into making these arms lighter, stronger and more rigid than the original Traxxas units, all whilst improving overall durability and crash resistance. The result is a suspension component that professional racers and serious enthusiasts trust.
Key Features
- 64% More Material Around Hinge Pins — RPM increased the material surrounding both the inner and outer hinge pin locations by a remarkable 64%, creating dramatically stronger connection points that resist bending and failure during high-speed impacts and aggressive cornering. This focused reinforcement eliminates the weak points that plague stock arms during competitive racing and hard bashing.
- 10% Weight Reduction Despite Added Strength — Through intelligent design and the removal of unnecessary shock mounts and holes required for multi-platform compatibility, RPM managed to reduce overall weight by over 10% compared to factory arms. This lighter unsprung mass improves acceleration, braking and handling dynamics without sacrificing durability.
- Slash 2WD-Specific Design — Unlike universal A-arms designed to fit multiple vehicles, these components are engineered exclusively for the Traxxas Slash 2WD. This focused engineering approach eliminates unnecessary features and optimises every detail for your specific platform, removing potential sources of flex and weakness.
- Improved Rigidity and Reduced Flex — The stiffer construction minimises suspension flex throughout the rear end, delivering a more responsive and predictable feel on the track. This enhanced rigidity makes these arms an excellent choice for race-level Slash trucks where consistency and precision handling are essential for competitive performance.
- Superior Crash Resistance — The cleaned-up geometry removes all the pockets and recesses where dirt, rocks and debris traditionally collect and become trapped. This design refinement dramatically reduces the chances of rocks wedging between the axle and A-arm during off-road use, preventing damage and maintaining peak performance during extended bashing sessions.
- Stock Geometry and Toe Angles Preserved — RPM retained the original Slash suspension geometry and rear toe angles, meaning you won't need to perform extensive set-up changes or recalibration. Your truck will maintain its familiar handling balance whilst benefiting from the upgraded strength and rigidity.
- Reduced Suspension Slop — The precision engineering of these A-arms eliminates most of the loose play found in stock rear suspension systems. Slash owners can further tighten the rear end by combining these with RPM Rear Bearing Carriers (sold separately), creating a locked-down suspension that responds instantly to driver input.
- Nearly Indestructible Materials — RPM moulded these A-arms from a specialised nylon blend engineered for extreme durability. The material offers excellent impact resistance, flex characteristics and reliability in demanding conditions, whether you're racing in the mud, sand or concrete.
- Lifetime Warranty Against Breakage — RPM backs these A-arms with a limited lifetime warranty against breakage, demonstrating absolute confidence in the engineering and materials used. This warranty reflects the brand's commitment to quality and gives you peace of mind during aggressive driving.
- Multiple Colour Options — Available in black, blue, green and red, these A-arms let you customise the look of your Slash whilst maintaining the same exceptional performance and durability across all colour variants.
Technical Performance
RPM engineered these rear A-arms using a specialised nylon material blend that delivers the ideal balance between strength, weight and impact resistance. The 64% increase in material around the inner and outer hinge pins creates substantially stronger connection points than factory components, allowing these arms to withstand the enormous forces generated by hard landings, aggressive cornering and high-speed impacts that would crack or bend stock arms. The design team then removed every unnecessary shock mount hole and suspension feature required for multi-platform vehicles, eliminating sources of flex and weak points whilst simultaneously reducing weight. Despite the significant added reinforcement, the final product comes in at over 10% lighter than original Traxxas arms, improving your Slash's acceleration and handling response. The precision engineering maintains stock suspension geometry and rear toe angles, so your truck's handling characteristics remain predictable and familiar. The revised suspension geometry also eliminates the deep pockets and recesses found in stock arms where dirt and rocks accumulate and become trapped between the axle and arm. The construction delivers dramatically improved rigidity and reduced flex compared to factory components, making these arms an essential upgrade for competitive racers and serious bashers who demand the best possible handling precision and durability from their 1/10 scale Slash 2WD RC truck. These A-arms replace the stock Traxxas unit number 2555X.
What's in the Box
- RPM Rear A-arms for Traxxas Slash 2WD (sold as a pair)
Important Technical Notes
- Lower Hinge Pin Location Only — Stock Traxxas rear axle carriers feature both upper and lower hinge pin holes. RPM Slash rear A-arms only support the original lower hinge pin location. The upper axle carrier hole cannot be used with these arms, as utilising it would lower the rear ride height excessively.
- Height Adjustment Method — To lower the rear of your truck, RPM recommends using the outer shock mount hole positions within the A-arm itself rather than adjusting hinge pin locations. This preserves geometry and delivers predictable handling changes.
- Nitro Slash Incompatibility — These rear A-arms are designed exclusively for the Traxxas Slash 2WD and are not compatible with the Nitro Slash platform.
- Optional Upgrade Component — For further suspension refinement and reduced play, RPM offers optional Rear Bearing Carriers (RPM 80382, sold separately) which work perfectly with these A-arms to tighten the rear end even further.
Frequently Asked Questions
- Are these rear A-arms compatible with my Traxxas Slash? — These arms are specifically designed for the Traxxas Slash 2WD platform. They are NOT compatible with the Nitro Slash or any other Traxxas model. Before purchasing, confirm you own a Slash 2WD (brushless VXL or brushed model).
- What makes RPM rear A-arms better than the stock Traxxas arms? — RPM increased material around the hinge pins by 64%, removed unnecessary holes and shock mounts specific to multi-platform arms, and reduced overall weight by 10% whilst dramatically improving rigidity and crash resistance. Stock geometry is maintained, so handling characteristics remain familiar whilst the truck feels noticeably tighter and more responsive.
- Will I need to adjust my suspension set-up when I install these A-arms? — No, because RPM retained the stock Slash suspension geometry and rear toe angles, you won't need to perform a full suspension re-setup. The installation is straightforward and your truck's handling will remain consistent.
- Can I use both the upper and lower hinge pin holes like the stock arms? — No, RPM specifically designed these arms to use only the lower hinge pin location. Using the upper hole would excessively lower the rear ride height and compromise handling. To lower the rear, adjust shock mount positions instead.
- What colour options are available for this product? — RPM manufactures these rear A-arms in four colours: black, blue, green and red. All colour variants offer identical performance and durability.
- Are these A-arms covered by a warranty? — Yes, RPM backs all Slash 2WD rear A-arms with a limited lifetime warranty against breakage, reflecting the company's confidence in the material quality and engineering.
- What material are these A-arms made from? — RPM moulded these arms from a specialised nylon blend engineered specifically for extreme durability, impact resistance and the correct flex characteristics required for off-road RC racing.
- Can I further improve the rear suspension by combining these with other upgrades? — Yes, RPM sells optional Rear Bearing Carriers (RPM 80382, sold separately) which work perfectly alongside these A-arms to remove additional play and tighten the rear suspension system even further for maximum precision handling.
- How much weight is saved by upgrading to these RPM A-arms? — RPM managed to reduce weight by over 10% compared to stock Traxxas arms, despite adding 64% more material around the critical hinge pin locations. This weight saving improves acceleration and overall handling response.
- Are these good for both racing and bashing? — Yes, these A-arms are excellent for competitive racers who demand precision and consistency on the track, and equally suited to weekend bashers who appreciate the superior crash resistance and durability. The improved rigidity and reduced flex benefit any serious Slash 2WD owner.
