The JR-TRX407-BK aluminium hold down is an accessory for the Traxxas TRX-4 chassis that provides a rigid method to secure the battery in the vehicle bay. Its black finish is intended to blend with scale components without drawing attention away from the model layout.
Fitting normally requires no chassis modification: the plate locates to the factory battery area using existing mounting points and hardware so you can replace the stock hold-down easily. Use standard hand tools and check wire placement before fully tightening the fixings.
In practical use the hold down reduces battery movement that can affect balance and cable strain on rough terrain, supporting reliable power connection during extended trail runs and technical crawling sessions.
