Hardened 89T Spur Gear for Enduro SENDERO

This is an RC-scale 89T spur gear made for the ENDURO SENDERO Trail Truck platform, offered by GPM as part ES089TS. The part is machined from hardened steel #45 and is intended as a direct-replacement upgrade to increase effective drivetrain torque without changing the motor pinion.

Placement is besides the motor gear in the transmission train, so verify mesh and backlash when installing. Because this item increases tooth count from the stock 87T to 89T, expect a modest change in low-speed torque and drivetrain loading; adjust pinion mesh and check set screws and bearings after the first run.

Use this gear when you need slightly more low-speed pulling force or prefer a sturdier steel spur for trail and technical crawling duties while retaining your existing motor gear ratio.
