ARRMA Mojave Differential Case for 1/7-1/8 Desert Trucks MAJ011 by GPM  [MAJ011]

This replacement differential housing is an aftermarket part made for ARRMA 1/7 and 1/8 scale desert trucks and related platforms. The outer section is medium carbon steel to resist wear where gears and bearings contact, and the centre piece is machined from 7075 aluminium to cut rotating mass while keeping mounting stiffness. A rubber sealing ring is supplied to limit contamination and retain lubricant within the gearbox.

For drivers who run long sessions or push their trucks hard, the unit adds chassis-level reinforcement: it helps keep gear mesh stable under load, reduces the risk of premature gear wear, and maintains consistent differential performance. It is designed for direct replacement of the factory differential housing on compatible ARRMA models; always check chassis and axle layouts for fitment before fitting.

Fitting tips: follow your vehicle manual to remove the axle or centre gearbox, move the internal diff components into the new housing, install the provided sealing ring, and torque fasteners to the original specifications. Verify gear backlash and lubrication after assembly and inspect again after the first run.
