Ring and Pinion overview

This GPM SLA1337RS ring and pinion set is an aftermarket 40CR steel spiral-cut gear pair intended for RC-scale drivetrain use, supplied as a 37-tooth ring and a 13-tooth pinion that mount inside the rear gearbox to transfer power along the driveline. The spiral-cut tooth profile is designed to promote smoother engagement under load compared with straight-cut gears, and the parts are presented as direct replacement items for models listed in the compatibility block below.

For installation and tuning, confirm correct gear mesh, inspect related bearings and seals, and secure gear fasteners before test-running the model; correct mesh and alignment are the primary factors that affect noise, wear, and drivetrain smoothness when fitting steel aftermarket gears.

Packing includes

  • 37-Tooth ring - 1pcs
