The engineering behind this product demonstrates RPM's commitment to solving real-world problems faced by RC enthusiasts, making it an essential upgrade for anyone serious about maximising their truck's performance and consistency.

Whether you're competing at the track or enjoying recreational bashing sessions, the RPM Front Offset A-arm delivers the kind of thoughtful engineering that separates quality aftermarket parts from standard factory components. These arms are proven through RPM's existing front A-arm design for the Traxxas Slash and Nitro Slash platforms, ensuring reliability and precision fit every time you take your truck out.

Key Features

• Offset Compensation Design — These front A-arms are specially lengthened to compensate for the difference between front and rear wheel offsets, allowing you to run rear-offset wheels on the front of your truck without compatibility issues. This eliminates the frustration of managing multiple offset configurations and ensures consistency across your entire wheel and tyre setup.
• Rear Offset Wheel Compatibility — The extended length allows you to use rear-offset Traxxas wheels or RPM Revolver wheels (models #82332 or #82333) on the front of your truck, giving you much greater flexibility in your wheel and tyre selection without requiring different offset variants.
• Enhanced Stability Option — When paired with appropriate wheel choices, these A-arms can provide an additional 3mm of width per side in both the front and rear compared to standard geometry setups, which adds measurable stability to your Traxxas Nitro Slash 2WD during acceleration, braking and cornering.
• Engineering-Grade Nylon Construction — Built from RPM's proven blend of engineering-grade nylon compounds, these A-arms deliver exceptional durability and resistance to impacts, crashes and the stresses of competitive racing or aggressive bashing without excessive weight penalties.
• Direct OEM Replacement — These offset-compensating front A-arms replace the standard Traxxas #3631 part, making installation straightforward and ensuring perfect fitment on both the Traxxas Slash 2WD and Traxxas Nitro Slash platforms.
• Limited Lifetime Warranty — RPM backs these front A-arms with their comprehensive limited lifetime warranty against breakage, giving you peace of mind and demonstrating the manufacturer's confidence in the durability and reliability of their engineering.
• Proven RPM Design Heritage — These offset-compensating A-arms are based on RPM's already proven and tested design for standard Slash front A-arms, meaning you benefit from years of real-world development and customer feedback in their engineering.
• Perfect for Wheel Standardisation — Whether you want to simplify your spare parts inventory or run the same wheel offset all around for maximum convenience, these A-arms make it practical and straightforward, particularly valuable when racing multiple heats or switching between different track conditions.

Technical Performance

The RPM Front Offset A-arm represents a masterclass in practical RC engineering for the short course truck market. These components are manufactured from engineering-grade nylon, a material choice that reflects RPM's understanding of the balance needed between weight, strength and impact resistance in competitive 2WD off-road racing. The offset-compensating design extends the front A-arms to precisely match the geometry changes created by rear-offset wheels, eliminating the binding, misalignment or inconsistent handling that can occur when using mismatched wheel offsets on short course trucks. The extended length adds approximately 3mm per side to the overall track width, which can be leveraged for improved stability during high-speed turns, aggressive acceleration out of corners, and dynamic weight transfer situations that demand responsive chassis geometry. While this extra width may not be legal in sanctioned racing classes with strict geometry specifications, it proves invaluable for recreational bashing, hobby running and fun sessions where maximum stability counts. The A-arms work in conjunction with the Traxxas Slash 2WD and Nitro Slash suspension geometry to maintain proper camber, toe and other critical alignment angles, ensuring predictable handling and tyre wear characteristics. Built to withstand the punishment of repeated impacts, cornering forces and the general rigours of RC short course truck operation, these A-arms complement the stock Traxxas chassis while offering the dimensional advantages that come from their extended design.

Compatibility and Wheel Requirements

These offset-compensating front A-arms are designed specifically for the Traxxas Slash 2WD and Traxxas Nitro Slash. They require rear-offset Traxxas wheels or RPM Revolver wheels (models #82332 or #82333) to be mounted on the front of your truck for proper fitment and performance. If you choose to use standard 2WD front-offset wheels instead, the stance will widen but may cause rubbing on the body, requiring additional wheel well clearance modifications to your truck's bodywork. This makes the A-arms ideally suited for users who standardise on rear-offset wheels across their entire vehicle.

Frequently Asked Questions

• What is the purpose of offset-compensating front A-arms for RC short course trucks? — The primary purpose is to allow you to run rear-offset wheels on the front of your truck without compatibility issues. Standard RC short course trucks use different offset wheels front and rear, which can make wheel management complicated. These lengthened A-arms compensate for that offset difference, letting you standardise on rear-offset wheels across front and rear for simplicity, consistency and reduced spare parts inventory.
• Will these A-arms fit my Traxxas Slash 2WD? — Yes, these RPM front offset A-arms are specifically designed as a direct replacement for the Traxxas #3631 OEM front A-arms on both the Traxxas Slash 2WD and Traxxas Nitro Slash, making installation straightforward and ensuring perfect fitment.
• What wheels do I need to use with these A-arms? — These offset-compensating A-arms are designed to work with rear-offset Traxxas wheels or RPM Revolver wheels (specifically models #82332 or #82333) mounted on the front of your truck. Using standard front-offset 2WD wheels will cause the stance to widen but may result in body rubbing that requires additional wheel clearance.
• How much wider will my truck be with these A-arms? — When properly configured with rear-offset wheels on the front, these A-arms provide approximately 3mm additional width per side in both front and rear, for a total of 6mm additional width at each end of the truck, which translates to improved stability during acceleration, cornering and braking.
• Are these A-arms street legal for racing? — The additional width provided by these offset-compensating A-arms may not comply with strict sanctioned racing class specifications that mandate specific geometry parameters. However, they are perfectly suited for recreational bashing, hobby use and fun sessions where the added stability is genuinely beneficial and the geometry restrictions don't apply.
• What material are these A-arms made from? — RPM Front Offset A-arms are manufactured from engineering-grade nylon compounds, the same proven material used in RPM's standard Slash front A-arm designs. This material provides an excellent balance of strength, impact resistance, durability and weight efficiency for demanding RC short course truck applications.
• How durable are RPM A-arms compared to plastic OEM parts? — RPM's engineering-grade nylon is formulated to be significantly more impact-resistant than standard plastic, and RPM backs all their A-arms with a limited lifetime warranty against breakage, demonstrating exceptional confidence in the durability and reliability of their parts.
• Can I use these on my Traxxas Nitro Slash? — Yes, these RPM front offset A-arms are compatible with both the Traxxas Slash 2WD and the Traxxas Nitro Slash, making them a versatile upgrade for nitro-powered short course truck enthusiasts.
• What is the difference between offset-compensating A-arms and standard geometry A-arms? — Standard geometry front A-arms are designed to work with front-offset wheels as originally specified by Traxxas. Offset-compensating A-arms are lengthened to compensate for rear-offset wheel geometry, allowing you to standardise on rear-offset wheels across the entire truck for simplicity and consistency in wheel management.
