Upgrade to the GPM TRV057RS alloy rear upper arm to give your Traxxas Revo 3.3 a more robust rear suspension point. The alloy construction provides better durability while the sandwich-style design with supplied screws and pins locks the arm in place for improved stability under load.
Hand-tighten and then torque fasteners to a safe setting, then inspect after initial runs. Regular maintenance checks will ensure continued reliability from the upgraded arm.
