TRAXXAS E-REVO Aluminium Rear Bulkhead by GPM ER013A  [ER013A]

Aluminium rear bulkhead for E-REVO

This aluminium rear bulkhead is an RC-scale replacement part designed for the TRAXXAS E-REVO platform and supplied by GPM as ER013A in a 1pc set. The component serves as the rear structural mount that ties the gearbox and suspension pickup points together, using machined aluminium to replace the stock plastic unit for a firmer mounting surface.

Installation is straightforward for experienced model technicians: remove the existing rear bulkhead, transfer any seals or inserts that fit into the new aluminium piece, align the gearbox and suspension mounts, and secure using the original fasteners. Follow your chassis manual for torque values and sequence to avoid overstressing plastics or bearings.

In tuning terms, swapping to an aluminium rear bulkhead provides a more stable reference for suspension geometry and driveline alignment, which can reduce flex under load and make setup changes (shock position, toe, camber link lengths) more repeatable. It is a component aimed at hobbyists focused on chassis consistency and durability during regular off-road running and repair cycles.
