TRAXXAS CRANIAC Durable Aluminium Spur Adapter and Steel 60T & 16T Gear Set CRA156016T by GPM  [CRA156016T]

Replacement spur adapter for CRANIAC

This aluminium spur gear adapter with steel 60T and 16T gears is a direct-fit aftermarket option for the TRAXXAS CRANIAC MONSTER TRUCK. It is intended to increase drivetrain durability and support stable gear engagement while preserving the original gearbox layout.

Fitment steps: remove the existing spur assembly, insert the aluminium adapter into the gearbox hub, align the steel 60T spur with the pinion, and secure using the existing chassis hardware. Confirm correct gearmesh and run the gears briefly at low speed to ensure smooth engagement.

Performance note: the aluminium adapter helps maintain shaft alignment under load and the steel gear set offers improved wear resistance compared with softer spurs, which assists in keeping consistent backlash during heavy running or competitive use.

Fit this set when you want firmer seating and longer tooth life for the CRANIAC drivetrain; always recheck mesh and lubrication after installation and again after the first run.
