More info
The Traxxas 13T Pinion Gear is a heavy-duty 32-pitch pinion machined from hardened steel to withstand repeated use. It fits 3 mm motor shafts and includes a set screw for positive, secure mounting. Swapping to this 13-tooth pinion makes it easy to fine-tune acceleration versus top speed for different tracks and driving styles.
This 13T pinion gear is a straightforward, durable upgrade or replacement for Traxxas models that use 32-pitch gearing. The hardened-steel construction extends service life under high-load conditions, and the included set screw simplifies installation so you can get back on the track faster.
