Baja 5B owners, your gearing options are here! This new 17 Tooth Heavy Duty Pinion Gear is a direct replacement for the stock 17 tooth pinion gear. Precision machined from high carbon steel for a smoother finish to the teeth and more precise roundness, this gear has less friction for quieter running, increased efficiency and longer life than the stock gear. Also included is a machined aluminum Pinion Gear Heat Sink that helps cool the gear and clutch for longer spur gear life.
Mounting hardware, heat sink and instructions are included.
