ARRMA Mojave 6S Front/Center/Rear Differential Outdrive by GPM MAJ039S  [MAJ039S]

Differential outdrive overview

This GPM MAJ039S outdrive is an RC-scale replacement designed for ARRMA Mojave and related 1/7–1/8 EXB platforms. It serves as the interface between the drivetrain CVD or dogbone and the differential, transferring torque while keeping the dogbone retained during aggressive off?road use.

The part is manufactured in 4140 medium carbon steel and is supplied as a pair of outdrives. One flank of the outdrive is intentionally lengthened by 3mm to reduce the chance of dogbones slipping out under heavy suspension articulation and impacts. The geometry is intended to match ARRMA differential assemblies so it fits in front, center, or rear differential housings that accept the same interface.

Installation notes: confirm the differential housing and CVD/dogbone interface match the original ARRMA items before fitting, use the supplied rubber washers where specified to ensure correct spacing and preload, and check clearance during initial test runs. The component functions as a direct mechanical replacement in RC drivetrains and is not for any full?scale vehicle use.
