CNC-machined 7075 aluminium rear differential housing optimised as a direct-strength replacement for the rear gearbox on specified TRAXXAS 1/10 4WD models. The design emphasises dimensional accuracy, increased stiffness and a heatsink-style surface to aid thermal dispersion around the gearbox area under sustained loads.
Engineering intent: the component retains OEM differential and bearing datum locations while raising torsional stiffness to reduce deformation under high torque and lateral loads. It is intended for hobbyists and tuners pursuing consistent gear mesh, refined diff behaviour and improved drivetrain durability in performance setups.
Service guidance: the housing ships with the fasteners in the packing list below. Installation requires controlled disassembly of the rear gearbox, careful transfer of internals, and calibrated torque application during reassembly. Inspect bearing interference fits and verify gear engagement before operating at full motor power.
Part location: Rear gear box area
Use this RUS4013N 7075 aluminium housing where precise fit, higher stiffness and improved thermal dispersion are required to support tuned diffs and higher power drivetrains.
