Technical Performance
The RPM Extended Left Rear A-arms are precision-engineered suspension components designed specifically for the Traxxas Summit, Revo, and E-Revo platforms. Built around RPM's proven Revo rear A-arm design, these extended arms combine exceptional durability with minimalist weight, creating a suspension upgrade that will transform your vehicle's handling and longevity. The moulded construction utilises high-strength polymer materials that resist cracking and failure under extreme driving conditions. Available with either 10mm or 19mm extension options, these arms allow you to dial in your vehicle's geometry to match your specific driving style and terrain preferences. The engineering incorporates all original stock suspension geometry, ensuring that your suspension angles, camber, and caster settings remain optimised for balanced handling. Installation requires 6mm bumper mount spacers (not included) and M3 x 16mm screws (not included) if you're replacing standard wheelbase A-arms with these extended versions. The detailed installation instructions available from RPM provide comprehensive technical guidance for proper fitment and setup. Whether you're running your RC car on challenging terrain, competitive tracks, or open-field bashings, these A-arms are engineered to deliver the reliability and performance that serious RC enthusiasts expect.

Frequently Asked Questions
- Are RPM Extended Left Rear A-arms compatible with my Traxxas Summit or Revo? — Yes, these extended rear A-arms are specifically designed as replacement parts for the Traxxas Summit, Revo, and E-Revo. They replace stock Traxxas part numbers #5327, #5333R, and #8633. If you own any of these models, these extended arms will fit your vehicle's rear suspension mounting points.
- What is the difference between the 10mm and 19mm extension options? — The 10mm and 19mm options refer to how much the wheelbase is extended. The 10mm extension provides a subtle geometry change that slightly increases stability, whilst the 19mm extension delivers a more noticeable wheelbase lengthening that can significantly alter handling characteristics, typically providing improved planted feel and reduced turning radius.
- Will I need any additional parts to install these extended A-arms? — If you're replacing standard wheelbase A-arms with these extended versions, you will need 6mm bumper mount spacers and M3 x 16mm screws, which are not included in the package. RPM provides detailed installation instructions that specify exactly what additional components you may need for your particular setup.
- How durable are RPM extended rear A-arms? — These A-arms are engineered to be nearly indestructible, with a robust moulded design that resists cracking and breaking under extreme driving conditions. They're backed by RPM's limited lifetime warranty against breakage, giving you confidence in their durability for years of serious RC use.

Their proven design and exceptional durability make them ideal for drivers who demand reliability in any situation.
- Do these extended A-arms affect my vehicle's turning radius? — Yes, the extended wheelbase created by these A-arms will typically reduce your vehicle's turning radius slightly, making sharper turns more achievable. This is particularly noticeable with the 19mm extension option, which provides more significant geometry changes.
- What warranty coverage do these A-arms include? — RPM Extended Left Rear A-arms are backed by a limited lifetime warranty against breakage. This comprehensive coverage protects your investment and demonstrates RPM's confidence in their product quality and engineering.
