17-tooth steel pinion for Baja platforms

This hardened 17T steel pinion is an aftermarket option for Baja 5b, Baja 5b Ss and Baja 5T vehicles, aimed at reliable tooth engagement and practical durability for hobby use.

Fit and pairing: intended to pair with the SBJ057T spur to establish proper mesh and extend gear life. Before fitting check motor shaft fit, ensure the set screw is secured, and perform a rotation test to confirm free, even contact across the gear teeth.

Tuning guidance: installing a 17T pinion moves gear ratio toward quicker acceleration versus higher top speed. Make step changes and keep an eye on motor temperature and ESC load to avoid overloading electronics.

Care tips: after running inspect for chipped teeth or excessive wear, keep the gear clear of sand and grit, and confirm bearings and motor mount are tight to maintain consistent mesh and quieter running.

Specifications

  • Item: Steel pinion gear
  • Material: Steel
  • Model Number: SBJ017T
  • Compatibility: Baja 5b, Baja 5b Ss, Baja 5T

A no-nonsense steel pinion for RC tuners altering gear ratios on specified Baja models; match with the recommended spur and verify mesh on installation.

Is the SBJ017T pinion compatible with brushless setups?

Compatibility depends on motor shaft and mounting; the pinion itself suits both brushed and brushless motors if the shaft diameter and set screw position match your motor.

Why pair with SBJ057T spur gear?

The SBJ057T spur is specified to produce the intended tooth engagement and minimise uneven wear. Using a compatible spur helps maintain correct backlash and mesh.

Should I change ESC or cooling when switching gears?

Not usually, but monitor motor temperature after gearing changes. If temps rise, consider improved cooling or reverting to a different ratio to reduce load.

Any quick install tips?

Ensure a snug press fit on the shaft, set the pinion screw to spec, check full rotation for binding, and run a short test under light load to confirm behaviour.
