Front Differential and Upper Bulkhead for TRAXXAS XRT/X-Maxx XRT12KIT by GPM  [XRT12KIT]

Strength and materials summary

This GPM kit provides an aftermarket front diff set and upper bulkhead tailored to TRAXXAS XRT and X-Maxx vehicles. The assembly combines complete front differentials with a reinforced upper bulkhead and differential housing to handle the stresses of large-scale monster truck operation.

Internal gears are manufactured from 4140 carbon steel and receive heat treatment to enhance torsional strength and longevity. The set contains a 32T bevel diff gear and a 10T front pinion gear specified at module M1.6. The housings are CNC machined from 7075-T6 aluminum to improve stiffness without excessive weight gain.

The kit is supplied as a direct replacement for the factory front assembly on compatible models below, intended to increase drivetrain lifespan under repeated high-load use rather than alter basic vehicle dynamics.

For operators seeking improved longevity in large TRAXXAS drivetrains, this GPM replacement kit uses 4140 steel gearing and 7075 housings to better withstand heavy-duty RC usage.
