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

Upgrade spur adapter for CRANIAC Monster Truck

This aluminium spur gear adapter combined with steel 60T and 16T gears is a direct-fit aftermarket replacement for the TRAXXAS CRANIAC MONSTER TRUCK platform. The set aims to increase drivetrain robustness and maintain consistent gear engagement while keeping the original gearbox interfaces intact.

Fitting procedure: remove the stock spur assembly, position the aluminium adapter into the gearbox hub, mesh the steel 60T spur to the pinion, and secure using your factory hardware. Check and adjust gearmesh, then run briefly at low throttle to confirm smooth operation.

Setup benefits: the aluminium adapter reduces shaft deflection under load and the steel 60T and 16T gears resist wear better than softer materials, helping to stabilise backlash and extend service intervals for bashing or race use.

Use this set when you need firmer adapter seating and longer-lasting gear teeth for the CRANIAC drivetrain; always recheck mesh and lubrication after the initial run.
