This precision aftermarket assembly includes a CNC-friendly aluminium spur gear adapter and hardened steel 60T spur together with a hardened 15T pinion, supplied as a single upgrade set for TRAXXAS CRANIAC Monster Truck drivetrains. The components are engineered to deliver improved wear resistance and consistent mesh under tuning or high-load conditions.
The aluminium adapter locates the spur accurately relative to the motor pinion, reducing runout and helping preserve backing surfaces, while the hardened steel gears are selected for long-term dimensional stability under torque. Intended uses include higher torque motor installations and hobbyist applications that demand durability over time. Installation requires gearbox access and precise backlash setting to maintain smooth engagement.
Workshop guidance: measure shaft runout before fitting, ensure the adapter mounts flush and without axial play, apply a medium-strength threadlocker to mounting screws if required, and verify gear mesh at low and high throttle to confirm absence of binding. This set is supplied for model maintenance and drivetrain tuning purposes.
Recommended for hobbyists seeking a stiffer mounting platform and longer-lived gear faces when tuning or running higher power; confirm alignment and mesh carefully during installation to protect mating components.
