This 86-tooth spur is a precision aftermarket replacement intended for the TRAXXAS 1/10 2WD platforms listed below. Manufactured from hardened carbon steel with CNC-machined tooth faces and a 48P pitch, the component replaces the stock nylon spur to provide a stronger metal interface for rear gearbox torque transfer.
Installation notes for technicians: remove the rear gearbox cover, document existing mesh and shim arrangement, install the SSLA2W086T spur and use the supplied stainless 3*7*0.2 washers to refine engagement. Re-torque fasteners to the correct values and verify free rotation under light load before full-power testing.
Engineering considerations: steel spur integration alters contact stress on the pinion and bearings; inspect mating elements and consider periodic replacement of wear items. Confirm pinion pitch and tooth count compatibility with the 48P specification to maintain correct geometry and avoid accelerated wear. This part is designed for RC-scale drivetrain applications and must be used on compatible chassis only.

Use SSLA2W086T where a CNC-machined steel spur is preferred for consistent gear contact; monitor mating components and maintain correct mesh for optimal longevity.
