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

7075-T6 aluminium differential case overview

This aluminium front and rear differential case is an aftermarket gearbox shell intended for RC scale use, positioned at the front and rear differential locations within compatible TRAXXAS gearboxes. Machined from 7075-T6 aluminium to provide increased stiffness over standard plastic housings, the component helps protect and stabilise the internal differential gears during heavier duty or high-speed operation.

Installation is suitable for experienced modellers: remove the gearbox cover, transfer the internal differential components into the aluminium case, and secure using the supplied cap head screws and plastic washer. The case's role is to maintain component alignment and reduce flex that can affect gear mesh and drivetrain response; it does not alter gear ratios or internal gear designs.

For set-up and tuning, verify bearings and shims are correctly seated after installation, apply thread lock where appropriate to metal-to-metal fasteners if using high-power brushless systems, and re-check gear mesh under load before final gearbox closure.

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