Metal Gear F/R Transmission Module Set (ARA311156)

The Metal Gear Front/Rear Transmission Module Set for ARRMA vehicles is a pre-assembled, drop-in upgrade that replaces the front or rear drivetrain in ARRMA models.

Built around precision steel gears with a 1.35 module for durable, accurate tooth mesh, it sits in a tough composite differential case with a precise diff yoke to maintain alignment. The set uses high-strength steel internal gears and splined output shafts and arrives pre-filled with 10,000 cSt silicone oil for smooth, dependable operation. Ready to install, it drops into the front or rear of an ARRMA model, providing a straightforward, durable drivetrain upgrade.
