The GPM TRV057LS rear upper arm is a precision engineered aluminium replacement for the left rear of the Traxxas Revo 3.3. Constructed from high-grade aluminum, the arm is designed to increase structural integrity and provide consistent linkage alignment. The sandwich style assembly secures the unit with the included screws and pins to minimise movement at the joint.
Install using the supplied hardware and verify even torque across all fasteners to maintain geometry. Inspect the screw and pin fittings after initial testing runs and at regular service intervals to preserve performance and reduce stress on surrounding components.
