This 86-tooth spur is an aftermarket steel replacement for the TRAXXAS 1/10 2WD models listed below. Machined from hardened carbon steel to a 48P tooth profile with CNC-finished faces, it replaces the standard nylon spur to offer a metal option for rear gearbox power transfer and durability testing.
Installation is suitable for hobbyists familiar with basic TRAXXAS drivetrain work. Remove the rear gearbox cover, note current shims and mesh, swap in the 86T steel spur and use the supplied stainless 3*7*0.2 washers to set proper engagement. Re-torque mounting screws to the recommended values and ensure the driveline turns freely before use.
Tuning advice: metal spurs change contact and wear behaviour so check mating pinion and bearings regularly. Ensure your pinion is compatible with a 48P spur and set the gear mesh accurately to avoid binding or premature failure. This component is intended for RC drivetrain applications and must be fitted to the compatible models shown below.

Select this steel spur for a firmer gearbox option; replace worn mating parts as needed and confirm gear mesh carefully after installation.
