A hardened 17-tooth steel pinion designed as a robust aftermarket replacement for Baja 5b, Baja 5b Ss and Baja 5T platforms. The component focuses on consistent tooth engagement and long service life under normal hobby use.
Installation guidance: pair the pinion with the SBJ057T spur to reproduce the intended mesh. Confirm motor shaft fit, secure the set screw to the recommended torque, and perform a full-rotation check to ensure no binding and correct contact pattern.
Performance considerations: moving to SBJ017T adjusts the drive ratio toward stronger acceleration with reduced top speed. Monitor motor temperature and ESC current after changes and adjust gearing gradually to protect drivetrain components.
A hardened steel pinion for measured gearing adjustments on compatible Baja vehicles; ensure proper pairing and confirm mesh at installation.
