Spiral-cut ring and pinion details

This GPM SLA1337RS ring and pinion set is an aftermarket 40CR steel spiral-cut gear pair made for RC drivetrains, supplied as a 37-tooth ring and a 13-tooth pinion that fit into the rear gearbox to transmit torque through the driveline. The spiral-cut tooth form helps the gears engage more smoothly under load compared with straight-cut parts, making it a practical upgrade or service replacement for the compatible trucks listed below.

When fitting this steel set, verify the gear mesh and backlash carefully, check bearings and seals for wear, and torque fasteners to the recommended values before running. Proper mesh and alignment are the main factors that control noise, life, and drivetrain smoothness with aftermarket steel gears.

As a direct-fit aftermarket 40CR steel spiral-cut ring and pinion for the listed TRAXXAS 4WD platforms, SLA1337RS is a durable replacement to restore or refine drivetrain engagement; pay attention to mesh and bearing condition during installation to get the best results.

Which TRAXXAS gearboxes accept this 37T/13T set?

Refer to the Compatible Models list inside the compatibility box for the exact TRAXXAS chassis and model numbers that match SLA1337RS.

Will these spiral-cut gears reduce drivetrain noise?

Spiral-cut teeth tend to run quieter and smoother than straight-cut under load, but correct mesh and bearing condition are essential to minimise noise.

What should I check before installing the steel set?

Inspect gearbox bearings and seals, clean mating surfaces, set backlash accurately, and use thread locking or correct torque on fasteners as required.

Can I use the set with brushless power systems?

Yes, the 40CR steel gear pair is suitable for higher torque setups, but confirm gearbox load limits and ensure proper mesh to avoid accelerated wear.

Does the package include both gears?

Yes. The packing block lists one 37-tooth ring and one 13-tooth pinion included with this part number.
