Fit the GPM TRV057LS alloy rear upper arm to reinforce your Traxxas Revo 3.3 suspension. Manufactured from high-grade aluminum, this replacement arm adds strength while keeping ride geometry stable. The sandwich-style design locks the parts together using the included screws and pins to reduce movement under load.
When installing, tighten all screws and pins to the recommended torque for your setup, then recheck after a short run. Routine inspections of the fastenings will help prevent premature wear and keep handling consistent.
