Machined Underdrive Ring and Pinion Gear for TRX-4 (TRA8288)

The Traxxas TRX-4 Machined Underdrive Ring & Pinion Gear is an essential upgrade for enhancing the performance of your TRX-4 build. This heavy duty gear set features a unique underdriven design compared to the stock ratio, resulting in reduced wheel speed, perfect for tackling challenging terrains while maintaining control.

Built to withstand higher power ESC and motor systems, this underdrive gear gives you the durability needed for intense driving experiences. The package includes a 35T ring gear and a 10T pinion gear to ensure your setup is optimized for high performance.

For those looking to fine-tune their vehicle's handling, implementing an overdrive in the front axle while underdriving the rear can create an impressive dynamic. Various combinations are possible to suit your driving style; for instance, you can pair a standard front with an underdrive rear or achieve an even more dramatic effect by using overdrive in the front and underdrive in the rear.
