TRAXXAS CRANIAC Monster Truck Aluminium Spur Gear Adapter & 58T/19T Steel Gears by GPM CRA155819T  [CRA155819T]

Aluminium spur gear adapter and steel gears

This aftermarket set is an RC-scale spur gear adapter paired with two steel gears, intended for the TRAXXAS CRANIAC Monster Truck platform. The package combines an aluminium adapter component with steel 58T and 19T gears to serve as a direct replacement or upgrade for worn transmission parts in the CRANIAC drivetrain.

Designed for hobby use only, the components focus on drivetrain serviceability and tuning: the adapter positions the spur gear securely on the axle or countershaft interface while the 58T and 19T steel gears provide the specified gear count needed for standard CRANIAC gearing setups. Use this set when replacing damaged teeth, changing gear ratios for tuning, or as a spare for track or bash sessions.

Installation notes: confirm spline orientation and clearance before full assembly, ensure meshing and backlash are set to the chassis maker's recommended values, and verify that the motor pinion and spur align correctly with the gearbox layout of the CRANIAC platform. Regular inspection for wear and proper lubrication will extend service life.

Use this set when you need a like-for-like drivetrain part for the TRAXXAS CRANIAC, or when tuning gear ratios requires durable steel gears and a stable aluminium adapter to maintain consistent mesh and alignment.
