TRAXXAS E-REVO Front/Rear 7075-T6 Diff Case ER011N by GPM  [ER011N]

7075-T6 aluminum diff case overview

This aluminium front and rear differential case is an aftermarket gearbox shell built for RC scale use, intended to sit in the front and rear differential positions of compatible TRAXXAS gearboxes. Machined from 7075-T6 aluminium for greater stiffness than stock plastic shells, the unit helps stabilise and shield the differential gears during high-load runs and impacts common in fast or heavy use.

Installation suits experienced hobbyists: remove the gearbox cover, transfer the internal diff components into the aluminium housing, then fasten with the supplied screws and plastic washer. The case is designed to preserve alignment and cut flex that can alter gear mesh or drivetrain response; it does not change gear ratios or replace internal gear types.

For setup and maintenance confirm bearings and shims are seated correctly after fitting, apply light thread lock where recommended for metal-to-metal screws if you run powerful brushless systems, and re-check gear mesh under load before final gearbox assembly.

Used as a direct aluminium replacement for front and rear diff housings, this case focuses on reinforced protection and consistent gear alignment for the listed TRAXXAS platforms without changing internal gearing.
