Baja 5b Series 17T Steel Pinion Gear - SBJ017T by GPM  [SBJ017T]

17T steel pinion for Baja 5b line

A hardened 17-tooth steel pinion supplied as an aftermarket replacement for Baja 5b, Baja 5b Ss and Baja 5T vehicles. It is intended to deliver consistent tooth engagement and straightforward durability for scale RC drivetrain use.

Fit and pairing: this pinion is intended to be matched with the SBJ057T spur gear to obtain the correct mesh and reduce premature wear. Before mounting confirm motor shaft diameter, set screw torque, and check backlash by rotating the drive to verify smooth engagement without binding.

Tuning role: switching to a 17T pinion changes the effective gear ratio relative to stock choices, affecting acceleration and top speed in predictable steps. Make incremental gearing changes and monitor motor temperature and ESC load to keep components within safe limits.

Maintenance notes: inspect both pinion and mating spur for burrs or chipped teeth after running, keep gears free of grit and debris, and verify bearings and motor mount are secure to maintain a steady mesh and reduce noise.

A simple steel replacement for hobbyists changing gear ratios on compatible Baja platforms; pair with the recommended spur and confirm mesh during installation.
