The GPM CRA156014T replaces stock components on the Traxxas Craniac Monster Truck with a precision aluminium spur adapter and hardened steel 60T and 14T gears to offer a tougher drivetrain that copes better with sustained abuse.
Careful machining and material choice help the gears hold alignment under load, reducing slop and the risk of premature tooth chipping during heavy use.
Components are produced to fit the Craniac gearbox without modification, making this a practical upgrade for both workshop installs and field repairs.
