GPM Steel Pinion Upgrade SBJ01618TO

This GPM SBJ01618TO pinion set delivers hardened steel pinions in 16T and 18T sizes for precise engagement on HPI Baja drivetrains. The components are aimed at hobbyists and tuners seeking improved wear resistance and predictable gear behaviour when paired with the stock spur or the Sbj057T option.

Technical Highlights

Supplied as 16T and 18T pinions, machined for repeatable tooth geometry and consistent mesh.
5mm bore for direct motor shaft installation on standard HPI Baja platforms.
Hardened steel construction reduces profile wear under high torque runs.
Compatible with both factory spur gear and Sbj057T upgraded spurs to support tuning choices.

Packing includes

1x 16T Steel Pinion Gear
1x 18T Steel Pinion Gear

What installation checks should a tuner perform?

Verify motor shaft runout, set correct backlash at the pinion to spur interface, and confirm set screw torque to avoid slippage under peak loads.

How does material choice affect maintenance intervals?

Steel pinions resist surface fatigue longer than softer alloys, extending inspection intervals but still requiring regular checks for nicks and burrs in abrasive conditions.

Are these suitable for high KV brushless motors?

They are compatible with brushless setups, but match pinion tooth count and motor gearing to expected torque and RPM to avoid excessive stress on gearbox components.
