Spiral-cut gear summary

The SLA1337RS set is a 40CR steel spiral-cut ring and pinion offered as an aftermarket replacement for selected TRAXXAS 4WD gearboxes. The kit contains a 37-tooth ring and a 13-tooth pinion that locate inside the rear gearbox to pass torque through the driveline, and the helix tooth shape helps provide smoother engagement than straight-cut gears.

Before you run the model, confirm the gear mesh, inspect bearings and seals for wear, and make sure gear mounting hardware is secure. Proper mesh and alignment are the key elements that affect chatter, wear rate, and overall drivetrain feel when fitting steel aftermarket gears.

Offered as a direct replacement for the compatible TRAXXAS platforms, SLA1337RS provides a robust 40CR steel spiral-cut option to restore or adjust gear engagement; careful setup will extend service life.

How do I check gear mesh on this set?

Fit the pinion and ring, add a small strip of gear marking compound or paint, rotate to observe contact pattern and adjust until the load patch sits across the tooth face without edge contact.

Are any shims or spacers supplied?

The kit contains the ring and pinion only as listed in the packing block; use vehicle-specific shims or spacers from the original gearbox if required.

Will these be stronger than stock plastic gears?

40CR steel offers higher wear resistance and torque capacity than typical plastic gears, but correct installation and lubrication are important to avoid premature damage to mating components.

Does the set fit both rear and front gearboxes?

This pair is intended as the rear gearbox ring and pinion in the listed TRAXXAS models; confirm gearbox orientation and part numbering before swapping between positions.
