GPM SBJ017T - Steel Pinion Gear 17T for Baja 5b/5b Ss/5T, 1pc  [SBJ017T]

17T Steel Pinion for Baja 5b Series

This steel 17-tooth pinion from GPM is an aftermarket replacement intended for RC scale use on Baja 5b, Baja 5b Ss and Baja 5T platforms. The part focuses on basic durability and correct tooth engagement when matched with the complementary spur gear specified by the manufacturer.

Fit and pairing: this pinion is designed to be used with GPM SBJ057T spur gear to achieve the intended gear mesh and to avoid premature wear. Before installation check motor shaft fit, secure mounting set screw torque, and verify backlash using a single rotation test to ensure the teeth engage cleanly without binding.

Tuning role: changing to a 17T pinion alters the effective gear ratio compared with stock options, affecting acceleration and top speed trade-offs in a predictable way. Use this pinion as part of incremental gearing changes while monitoring motor temperature and ESC load to keep components within safe operating ranges.

Maintenance notes: inspect the pinion and mating spur for burrs or chipped teeth after use, keep the gear clean of debris, and confirm bearings and motor mounting are secure to preserve consistent mesh and minimize noise.

This pinion is a straightforward steel replacement for hobbyists adjusting gear ratios on compatible Baja platforms; pair it with the recommended spur and confirm proper mesh during installation.
