TRAXXAS CRANIAC Aluminium Spur Adapter & Steel 58T-15T Set - CRA155815T by GPM  [CRA155815T]

Precision aluminium adapter with hardened steel gears

This replacement kit supplies an aluminium spur gear adapter together with hardened steel 58T and 15T gears for the TRAXXAS CRANIAC monster truck platform. It is supplied to replace the factory spur adapter and plastic gears and is intended for scale drivetrain applications where metal components are required for testing or increased wear resistance.

Technical fit notes: the aluminium adapter accurately locates the spur gear on the output shaft while the 58T spur and 15T pinion replace the original plastic set. Confirm shaft diameter, gearbox clearance, and spline engagement prior to final assembly. During setup, adjust mesh and backlash to industry practice and ensure the gear faces are parallel to the spur mounting plane.

Service and inspection: after installation perform a controlled run-in, then inspect gear contact patterns, backlash, and fastener torque. Routine checks will identify any misalignment or premature wear so the drivetrain can be adjusted before extended use.

This GPM CRA155815T assembly gives technicians a metal adapter and steel gear set for evaluating and upgrading TRAXXAS CRANIAC drivetrains; verify mesh and clearances as part of standard procedure.
