GPM Racing Harden Steel #45 Pinion Gear 19T for Losi 1/6 Super Baja Rey 4x4 (SSB019T)

Precision 19T pinion for SUPER BAJA drivetrains

High-accuracy 19-tooth steel motor pinion manufactured as an aftermarket replacement for the Team Losi SUPER BAJA platform. The component engages the motor output shaft and transmits torque into the transmission, forming the initial stage of the gear train interface.

Produced from hardened steel #45 for improved surface hardness and fatigue resistance under repeated mesh cycles. The source package contains 1 pcs pinion gear and 1 pcs stainless steel screw shaft 5x5 and is listed under manual number LOS252079.

Installation and setup: mount the SSB019T pinion square to the motor shaft, set correct backlash and mesh with the spur gear to minimise pitting and premature wear, and verify free, no-load rotation before operational use. Use the 19-tooth sizing when calibrating final drivetrain ratios to tune torque delivery and top-end speed.

This item is compatible with

• TEAM LOSI Super BAJA REY 4X4
• 1/6 4WD SUPER BAJA REY 2.0 - LOS05021

What components are shipped with the pinion?

The package as supplied includes the 19T pinion and one stainless steel 5x5 screw shaft, matching the source listing.

Why use hardened steel #45?

Hardened steel #45 provides a balance of machinability and increased wear resistance, extending service life under repetitive gear engagement in RC drivetrains.

Recommended setup checks after fitting?

Confirm axial seating, set proper pinion-to-spur backlash, inspect for smooth rotation without load, and retorque the stainless screw shaft after an initial running session. Write Product Review Please sign in your account before you can write any review. Sign In Close
