Overview

Beef up your drivetrain and upgrade your mini monster truck's power handling with the GPM Carbon Steel and Aluminium Complete Differential Set. Engineered specifically for high-demand brushless power systems, this comprehensive set includes fully assembled front, centre, and rear differentials. Built using a combination of heavy-duty 4140 carbon steel internal gears and 7075 aluminium housings, these differential assemblies deliver exceptional resistance to stripping, twisting, and thermal wear during aggressive off-road driving.

Featuring a heavy-duty internal structure with an enlarged 0.8mm gear module, the differential teeth provide deeper mesh engagement and greater surface contact than standard factory gears. This increased gear thickness transmits high motor torque more effectively while reducing energy loss across the front, centre, and rear gearboxes. Supplied pre-assembled with precision shims for gear tolerance adjustment, this direct bolt-on set fits seamlessly into the Traxxas Mini Maxx and Mini XRT platforms. Simply fill each differential housing with your preferred silicone fluid, install them into your chassis, and enjoy reliable drivetrain performance.
