TRAXXAS CRANIAC Monster Truck Spur Adapter with Steel 60T & 16T Gears CRA156016T by GPM  [CRA156016T]

Aftermarket spur adapter for CRANIAC drivetrains

This aluminium spur gear adapter matched with steel 60T and 16T gears is a direct-fit aftermarket replacement for the TRAXXAS CRANIAC MONSTER TRUCK platform. The set is designed to boost drivetrain durability and stabilise gearmesh while maintaining the vehicle's original gearbox interface.

Installation is straightforward: remove the stock spur and adapter, install the aluminium adapter into the gearbox hub, mesh the steel 60T spur with the pinion, and secure using your chassis hardware. Verify gearmesh and run the drivetrain briefly at low throttle to ensure smooth engagement before full use.

Tuning benefit: the aluminium adapter keeps shaft alignment under load and limits deformation, while the steel 60T and 16T gears provide better wear resistance than softer spur sets, helping to hold consistent backlash during heavy bashing or timed runs.

Choose this kit when you want firmer adapter seating and longer-lived gear teeth for the CRANIAC drivetrain; recheck gearmesh and lubrication after the first short run.
