TRAXXAS E-REVO VXL Front/Rear Differential Case by GPM ER011N  [ER011N]

Aluminium differential case overview

This aluminium front/rear differential case is an aftermarket gearbox shell intended for RC scale use, designed to sit at the front and rear differential locations inside compatible TRAXXAS gearboxes. Machined from 7075-T6 aluminium for improved stiffness compared with standard plastic housings, the part stabilizes and protects the internal differential gears under higher loads and repeated impacts common in high-speed or heavy-duty use.

Installation is straightforward for experienced hobbyists: remove the gearbox cover, transfer the internal components into the aluminium case, and secure with the supplied fasteners and washer. The case serves primarily to maintain alignment of diff components and reduce flex, which can affect gear mesh and drivetrain response; it does not change gear ratios or internal gear types.

For setup and tuning the part supports routine checks: confirm bearings and shims are seated correctly after fitting, use thread lock where recommended on metal-to-metal fasteners if you run brushless power, and re-check gear mesh under load before finalizing the gearbox assembly.

As an aluminium replacement for the front and rear diff housings, this part focuses on protective reinforcement and consistent gear alignment for compatible TRAXXAS models without altering internal gearing.
