TRAXXAS CRANIAC MONSTER TRUCK Compatible Aluminium Spur Adapter & Steel Gears 58T & 16T CRA155816T by GPM  [CRA155816T]

Machined aluminium adapter with hardened steel gears

This aftermarket set replaces the stock spur interface on the TRAXXAS CRANIAC MONSTER TRUCK with a precision-machined aluminium adapter and hardened steel spur and pinion gears (58T and 16T), supplied as a single set. The upgrade is intended for RC drivetrain use to deliver more consistent gear engagement and improved wear life compared with the softer factory components.

The adapter fits between the motor pinion and the internal spur assembly to centre alignment and reduce lateral movement. The steel 58T spur and 16T pinion maintain the tooth counts listed in the product name to keep the final drive ratio unchanged while increasing resistance to wear for repeated runs and tuning sessions.

Installation notes: this is a direct-fit upgrade for the CRANIAC platform using the existing motor mount and spur housing. When installing, set mesh using a fresh head-shim method and confirm motor thrust and axle clearance before applying full power. Apply light threadlocker where metal fasteners are used and re-check gear mesh after the first run.

For hobbyists who regularly adjust drivetrain setups or run on abrasive surfaces, this aluminium adapter paired with the steel 58T/16T gears delivers a durable replacement while keeping factory ratio and fitment for the TRAXXAS Craniac platform.
