TRAXXAS CRANIAC Aluminium Spur Adapter with Hardened 58T/19T Steel Gears CRA155819T by GPM  [CRA155819T]

Precision aluminium adapter with hardened steel gear set

This engineered kit pairs a CNC-friendly aluminium spur gear adapter with hardened steel 58T and 19T gears sized for the TRAXXAS CRANIAC Monster Truck drivetrain. The components are specified for aftermarket replacement and improved long term mesh stability under repeated loads.

The adapter locates the spur accurately on the spline interface while the hardened steel gears retain original tooth counts for reliable ratio changes and service repairs. Use the set for replacing damaged teeth, fitting a stronger spare, or fine tuning gear ratios where consistent engagement matters.

Assembly notes for technicians: verify spline orientation, confirm shaft clearance and backplate spacing, set gear mesh and backlash to recommended values, and ensure correct motor pinion to spur alignment to avoid edge loading. Inspect mating surfaces for burrs and apply appropriate gear lubrication to extend service intervals.

Recommended for hobbyists seeking a precision-fit replacement or a more durable gearset for TRAXXAS CRANIAC drivetrains; maintain correct mesh and lubrication to optimise life.
