TRAXXAS CRANIAC MONSTER TRUCK Precision CNC Aluminium Spur Adapter & Hardened Steel 58T/16T Gear Set CRA155816T by GPM  [CRA155816T]

Precision CNC aluminium adapter with hardened steel gearing

This aftermarket assembly replaces the stock spur interface on the TRAXXAS CRANIAC MONSTER TRUCK with a CNC-machined aluminium adapter mated to hardened steel spur and pinion gears (58T and 16T), supplied as one set. The design focuses on consistent tooth contact, reduced lateral play and long-term wear resistance compared with softer OEM components.

The adapter installs between the motor pinion and the internal spur assembly to centralise the drive line and maintain concentricity under load. The hardened steel 58T spur and 16T pinion preserve the listed tooth counts to keep final drive ratio unchanged while offering superior abrasion resistance for sustained brushless use and frequent setup adjustments.

Installation notes: the component is a direct-fit upgrade for the CRANIAC platform using the vehicle's existing motor mount and spur housing. During fitment follow a head-shim mesh procedure, confirm motor axial position and axle clearance, and apply recommended threadlocking to metal fasteners. Perform a post-install inspection and re-check mesh after the first run-in period.

Engineered for precision and durability, this aluminium adapter with hardened 58T/16T steel gears improves mesh consistency and service life for demanding RC drivetrain applications while maintaining factory ratio and fitment for the TRAXXAS Craniac platform.
