Description
Precision machined rear differential housing for Slash 4X4
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.

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.
What machining tolerances were prioritised for RUS4013N?
Datum accuracy and bore concentricity were prioritised to preserve bearing alignment and minimise runout when transferring the differential assembly into the new housing.
Is the heatsink surface purely cosmetic or functional?
The heatsink-style surface increases surface area to assist passive thermal dispersion; while not a replacement for active cooling, it reduces local heat buildup in the gearbox area.
Can this housing support higher torque without reinforcement?
7075 aluminium provides improved tensile strength and stiffness versus softer alloys, offering greater resistance to deformation; however, gearbox longevity also depends on gear and bearing condition and correct assembly practice.
