Replace the stock rear upper arm on your Traxxas Revo 3.3 with the GPM TRV057LS alloy unit to strengthen the left rear link. Made from high-grade aluminum, the component is intended to cut flex and preserve alignment during hard driving. The sandwich assembly secures components using the included screws and pins for dependable performance.
Fit the arm with all fastenings tightened to a consistent level. Check the screws and pins after initial runs and during regular maintenance to avoid loosening and uneven wear.
