More info
The Traxxas 90-Tooth Spur Gear is a 48-pitch replacement designed for Torque Control slipper clutches. Install it to change final drive ratios and fine-tune how your model accelerates versus how fast it tops out, so your setup suits bashing, track laps, or technical courses.
Use the Traxxas 90-Tooth Spur Gear when you want a modest step in gearing without changing pinion size. The 90-tooth count and 48-pitch profile match Traxxas gearing standards and provide predictable power delivery through the slipper system.
Why Choose This Spur Gear
- 90-tooth design for a deliberate change in gear ratio that favors acceleration or top speed depending on set-up.
- 48-pitch tooth profile made to match Traxxas drivetrain spacing and Torque Control slipper clutches.
- Simple swap that helps you tailor performance for different running conditions—track, trail, or backyard bashing.
About the Brand
Works perfectly
Picked up this 90t spur gear for my Bandit 'cause Castle Creations recommended it for the sv2/5700kv setup with a 12-15t pinion. I'm using a 22t pinion with it and it's amazing! Getting the gear mesh right is key for long-lasting performance, and I've never stripped a Traxxas spur. If you're gonna use it with a 26t pinion, you'll need to elongate the motor mount holes by about 1/16"-1/8" or it won't fit.
