This GPM Aluminum Wheel Hex and Lock set is designed to link the CVD to the wheel on ARRMA LIMITLESS models, delivering consistent torque transfer and enhanced drive stability. The component increases hex thickness from the original 4.5mm to 10.5mm to produce a wider wheel track and better lateral control. The hex form provides positive engagement with wheel hubs, the capped exterior reduces contamination from sand and dust, and the inner knurling secures the lock under load for dependable retention during demanding runs.
