This upgrade kit replaces the original spur interface on the TRAXXAS CRANIAC Monster Truck with a CNC-friendly aluminium adapter and hardened steel 60T and 14T gears, emphasising improved alignment stiffness and gear longevity for high-torque operation. The components are supplied as a single set intended solely for RC-scale vehicle use.
Recommended installation procedure for experienced hobbyists: remove the factory spur assembly, secure the aluminium adapter to the gearbox or carrier ensuring correct seating, fit the 60T spur and 14T pinion, then establish optimal backlash via motor height adjustment or precise shimming. Use appropriate threadlocker on steel fastenings where they mate with aluminium and verify bearing axial and radial clearance prior to initial operation.
Engineering note: the aluminium adapter increases structural rigidity relative to standard plastic alternatives, while the steel 60T/14T gear pair reduces tooth deformation under cyclic load, contributing to a more stable mesh pattern and extended wear life under repeated high-load events.
This kit is suitable where a stiffer spur mounting and hardened gearing are required for TRAXXAS CRANIAC platforms; adhere to proper mesh setup and fastener torque to ensure optimal performance.
