Technical Performance
The RPM Extended Right Rear A-arms represent a sophisticated engineering solution to a common request from the RC community. Built using advanced molding techniques and high-strength polymer materials, these components deliver a remarkable combination of lightweight construction and near-indestructible durability. The design builds directly upon RPM's proven Revo rear A-arm platform, which has earned respect from serious RC enthusiasts through countless hours of reliable performance in demanding conditions. The engineering incorporates all original stock geometry, ensuring that when you install these arms on your Traxxas Summit, Revo, E-Revo, or Summit 2.0, you're maintaining the carefully-balanced suspension characteristics that Traxxas engineered. The extension options—available in either 10mm or 19mm configurations—allow you to fine-tune your wheelbase length for specific driving conditions and personal preferences. Whether you're tackling rocky terrain, smooth tracks, or mixed conditions across the UK, these A-arms provide the extended platform you need for improved stability and weight distribution. The lightweight nature of these components means you're not adding unnecessary unsprung weight to your suspension system, which would negatively impact handling responsiveness and suspension articulation. Instead, you get extended wheelbase benefits with minimal mass penalty.
