Traxxas TRX-4 Machined Ring & Pinion Gear (11/34T)

The Traxxas TRX-4 Machined Ring & Pinion Gear is a heavy duty gear upgrade for your TRX-4 build. This ring and pinion gear set replicates the stock gear ratio, but is more durable and better suited to high power ESC/Motor systems. Package includes one ring gear and one pinion gear.

A popular tuning option is to overdrive the front axle, and underdrive the rear axle. This can be achieved using a variety of gear combinations. You can run standard in the front, and underdrive in the rear, overdrive in the front and standard in the rear - or for the most dramatic impact, run overdrive in the front and underdrive in the rear. See option list below.
