7075 aluminium rear diff housing for Slash 4X4

Replacement rear differential housing machined from 7075 aluminium to provide a direct-strength upgrade for the stock rear gearbox on listed TRAXXAS 1/10 4WD models. The machined alloy body features a heatsink-style surface to help shed heat around the gearbox under sustained brushless or high-torque operation.

Function and fit: this unit takes the place of the OEM rear gearbox housing while keeping the internal differential and bearing locations unchanged, offering improved rigidity to limit flex during hard acceleration, cornering, or rough surfaces. It is intended for builders tuning diff oil or upgrading motor and ESC combinations where gearbox stability matters.

Installation notes: the housing is supplied with the fasteners shown in the packing list below. Typical installation requires partial disassembly of the rear gearbox, careful transfer of the diff assembly, and methodical re-torquing of screws to the recommended values. Verify bearing seating and gear mesh before full-power runs.

Packing includes

  • Rear Differential Housing - 2pcs
  • Grade 12.9 black Round Head Screws 4x10 - 2pcs
  • Grade 12.9 black Round Head Screws 3x16 - 1pcs

Choose this 7075 alloy housing when you want a firmer rear gearbox foundation for tuning diff oil, adjusting gear mesh, or coping with higher-power motor and ESC setups on compatible TRAXXAS 4X4 platforms.

Will this replace the stock Slash 4X4 rear housing directly?

It is made to match the OEM mounting points for the listed models, but confirm screw lengths and part orientation during assembly to ensure a direct fit.

Are the mounting screws included in the kit?

Yes, the packing list above details the Grade 12.9 screws shipped with the housing for secure gearbox assembly.

How does 7075 aluminium help performance?

7075 aluminium provides higher stiffness and tensile strength compared to softer alloys, reducing housing flex and helping maintain consistent gear mesh under load.

Any reassembly checks after fitting?

Check bearing seating, confirm bevel gear mesh and driveline rotation, and tighten screws incrementally to avoid distorting the housing before running at full power.
