TRAXXAS E-REVO Front/Rear Aluminium Diff Shell ER011N by GPM  [ER011N]

7075-T6 aluminium diff case summary

This aluminium front and rear differential case is an aftermarket gearbox shell made for RC scale use, designed to occupy the front and rear diff positions inside compatible TRAXXAS gearboxes. Machined from 7075-T6 aluminium to increase rigidity versus stock plastic housings, the part helps protect internal differential gears under heavier loads and repeated impacts.

Fitting is aimed at hobbyists with gearbox experience: remove the original cover, transfer the diff internals into the aluminium shell, then secure using the supplied screws and plastic washer. The case keeps diff internals aligned and reduces flex that can upset gear mesh, but it does not alter gear ratios or the internal gear set types.

After installation, check that bearings and shims seat correctly, use thread lock sparingly on external metal screws if running high-output brushless motors, and confirm gear mesh under realistic load before final assembly.

As a direct aluminium replacement for front and rear diff housings, this case emphasises reinforced protection and consistent alignment for the compatible TRAXXAS models without changing the internal gearing.
