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

17T steel pinion for Baja 5b family

A hardened 17-tooth steel pinion supplied as an aftermarket replacement for the Baja 5b, Baja 5b Ss and Baja 5T chassis. Designed for straightforward durability and correct engagement with a matching spur.

Fit and pairing: use this pinion in conjunction with the SBJ057T spur gear to achieve the recommended mesh and reduce wear. Before tightening confirm motor shaft compatibility, set screw torque, and rotate the drivetrain to check for even tooth contact.

Tuning notes: fitting a 17T pinion shifts the gear ratio toward stronger acceleration at the expense of some top speed. Make changes stepwise and keep an eye on motor temperature and ESC load to ensure safe running conditions.

Maintenance advice: after each session inspect for chipped teeth or scoring, clear any sand or dirt from the gears, and check bearing and motor mount security to keep a stable mesh and reduce drivetrain noise.

A practical steel pinion for hobbyists tuning gear ratios on compatible Baja models; always pair with the suggested spur and confirm mesh at install.
