TRAXXAS CRANIAC Aluminium spur adapter and steel spur gears 58T & 18T CRA155818T by GPM  [CRA155818T]

Precision aluminium adapter and hardened steel spur gears

This GPM aftermarket assembly combines a CNC-style aluminium spur gear adapter with steel 58T and 18T spur gears engineered for the TRAXXAS CRANIAC Monster Truck drivetrain. The components are produced to provide improved wear resistance and consistent gear mesh compared with original plastic parts.

The aluminium adapter accurately positions the spur on the transmission output while the steel 58T and 18T gears provide durable mating surfaces for the pinion and gearbox internals. The set is supplied as a single replacement kit for service or tuning tasks on the CRANIAC platform.

Installation typically involves removing the factory spur and adapter, setting correct backlash and axial clearance with the pinion, and reusing the original mounting hardware. Inspect gearbox bearings and mating faces prior to final tightening to prevent binding and ensure reliable operation.

Engineered as a durable service kit for the TRAXXAS CRANIAC drivetrain, this aluminium adapter and steel gear set assists hobbyists seeking precision fitment and longer service intervals.
