GPM Racing 7075 Alloy Front Differential Housing (Larger Inner Bearings) for Traxxas 1/10 Rustler 4x4 VXL (RUS4012N)

Technical overview

This front differential housing is a precision 7075 aluminium replacement engineered for TRAXXAS Slash 4X4 and compatible TRAXXAS 1/10 and 1/7 models. The RUS4012N housing is CNC-machined to accommodate larger inner bearings and to locate directly at the front gearbox interface, providing a stiffer mounting surface compared with standard plastic housings. Fin-style milling on the external surface increases thermal surface area to aid cooling of the differential assembly under load.

The delivery includes the two housing halves along with the detailed set of Grade 12.9 fasteners and two 6x13x5 bearings to match common front gearbox rebuilds. The component is intended for enthusiasts seeking increased mechanical robustness and reliable fitment for higher stress or upgraded drivetrains.

For precision upgrade projects, this RUS4012N 7075 housing offers a CNC-machined solution to increase bearing support and front gearbox stiffness, intended to improve drivetrain durability in higher load applications.

What bearing sizes does this housing accept?

The housing is machined to accept the larger inner bearings specified in the packing list; verify bearing inner diameters and outer seating dimensions before press-fit installation.

Are the fasteners high strength?

Yes, the kit provides Grade 12.9 black fasteners to match the mechanical requirements of a hardened aluminium housing and to ensure secure assembly.

Installation best practice?

Use a bearing driver for accurate seating, check for correct backlash and shaft alignment after assembly, and torque the Grade 12.9 screws according to recommended settings for your drivetrain components.
