Overview of the spiral-cut gear pair

The SLA1337RS gear set is a 40CR steel spiral-cut ring and pinion supplied as a 37-tooth ring and 13-tooth pinion for RC 4WD drivetrains. Designed as an aftermarket replacement, the helix cut helps reduce impact on tooth engagement and can improve driveline smoothness relative to straight-cut items when properly setup.

During installation, confirm correct mesh and backlash, inspect bearings and seals, and secure gear bolts to prevent movement. Correct alignment and bearing condition are the main contributors to quiet running and long gear life with aftermarket steel gears.

SLA1337RS gives a strong 40CR steel spiral-cut option for the listed TRAXXAS 4WD platforms as a reliable replacement; ensure correct mesh and bearing condition when fitting to achieve the best durability and quietness.

Do I need special tools to fit the gears?

Basic modelling tools and a gear mesh gauge or feeler are sufficient; a torque driver and quality greases or marking compound help achieve correct setup.

How often should I recheck the mesh?

Check mesh after the first run, then during routine maintenance intervals, especially if you run in dusty or wet conditions that can accelerate wear.

Is lubrication required for these steel gears?

Use a recommended gear grease or lubricant on the ring and pinion to reduce friction and wear; avoid excess that can attract dirt into the gearbox.

Will these change vehicle gearing?

The 37T/13T tooth counts maintain the same ratio as similar stock sets; they are intended as direct replacements rather than changing final drive ratio.
