ARRMA Mojave Differential Outdrive Set for 1/7-1/8 EXB - MAJ039S by GPM  [MAJ039S]

Product overview and compatibility

The MAJ039S outdrive is an RC replacement part engineered for ARRMA Mojave and compatible 1/7-1/8 EXB platforms. It connects CVD or dogbone shafts to the differential, passing torque while retaining the dogbone under high load and aggressive driving.

Manufactured from 4140 medium carbon steel, the parts are supplied as a pair. Each outdrive features one flank extended by 3mm to help prevent dogbone disengagement under heavy articulation or impact. The shape and dimensions are intended to match ARRMA differential interfaces so the parts fit front, centre, or rear differentials that accept the same interface.

Fitment guidance: confirm your differential housing and CVD/dogbone interface match the original ARRMA components before installation. Use the supplied rubber washers where called for to obtain correct spacing and preload, and verify clearances during initial test runs. This is an RC drivetrain component and not suitable for full-scale vehicle applications.
