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

Precision spur adapter for CRANIAC gearboxes

This aluminium spur adapter combined with steel 60T and 16T gears is a direct-fit aftermarket replacement for the TRAXXAS CRANIAC MONSTER TRUCK platform. The assembly is intended to enhance drivetrain durability and maintain reliable gear engagement without altering the original gearbox geometry.

Installation procedure: remove the stock spur and adapter, locate the aluminium adapter into the gearbox hub, mesh the steel 60T spur to the pinion, and secure with existing hardware. Verify correct gearmesh and perform a controlled run-in at low throttle to confirm smooth operation and proper seating.

Technical advantages: the aluminium adapter preserves shaft alignment under load and reduces the risk of adapter deformation, while the steel 60T and 16T gears provide superior wear resistance versus softer spurs, supporting stable backlash and extended service life under high-load conditions.

Recommended when precise seating and greater gear longevity are required for competition or heavy-use CRANIAC drivetrains; confirm mesh and lubrication after installation and during initial running.
