The GPM Aluminum Pendulum Wheel Knuckle Weights are engineered to add precise, tuneable mass to the wheel hubs of the Traxxas TRX4. The design focuses on reliable ballast placement and corrosion resistant materials for regular field use.
Fitment is to the TRX4 front and rear outer knuckle cases using the provided 23mm hex adapter and hardware. Ensure correct shim and fastener torque to maintain alignment and avoid binding under suspension articulation.
