This machined aluminium rear bulkhead is a direct replacement part intended for TRAXXAS E-REVO chassis and supplied as ER013A in a 1pc set. The component replaces the factory plastic housing to offer a stiffer mounting surface that improves gearbox and suspension pickup alignment under load.
Installation should be carried out by technicians familiar with chassis assembly: remove the original bulkhead, transfer seals or bushings into the new unit, align drivetrain and suspension mounting points, and tighten the original fasteners to specified torque values. Proper assembly sequence reduces risk to bearings and adjacent plastic components.
From an engineering standpoint, upgrading to a machined aluminium bulkhead reduces compliance at the rear mounting datum, delivering a more repeatable reference for suspension geometry and driveline alignment. The result is improved setup consistency and reduced movement during aggressive off-road use.
