Turn your Traxxas TRX4 into a steadier crawler using the GPM Aluminum Pendulum Wheel Knuckle Weights. These weights add tunable mass at the wheels to help the rig track better over rocks and rooty sections.
Built for the TRX4 knuckles, these pendulum weights mount to the front and rear outer case with simple fasteners. They are a clean upgrade that gives more low speed poise without major surgery to the axle assemblies.
