Precision Front/Rear Differential Case 7075-T6 ER011N by GPM  [ER011N]

Precision machined aluminium diff case notes

This aftermarket front and rear differential case is a machined 7075-T6 aluminium gearbox shell intended for RC scale applications and to occupy the front and rear diff positions in compatible TRAXXAS gearboxes. The component increases housing stiffness compared with standard plastic parts, helping to protect differential gears and maintain alignment under sustained loads and impact events common in demanding use.

Fitting requires gearbox disassembly and transfer of the internal diff components into the aluminium shell, secured with the supplied fasteners. The case preserves component alignment and reduces flex-induced mesh variation; it does not alter gear ratios or substitute internal gear types.

For best results verify bearing seating and shim placement after installation, use recommended thread locking practices on metal-to-metal external fasteners in high-torque systems, and confirm gear mesh under operating load before final closure of the gearbox.

Engineered as a robust aluminium replacement for front and rear diff housings, this part focuses on precision fitment, reduced flex and consistent gear alignment for the listed TRAXXAS platforms while leaving internal gearing unchanged.
