Traxxas Pinion Gear 48-pitch 16-tooth pinion is a compact, direct-fit option for changing gear ratios and dialing in performance. It fits 3 mm motor shafts and includes a set screw for a solid, repeatable mount.
Why choose this pinion? The Traxxas Pinion Gear is a simple, effective way to tune your model for different conditions—swap to this 16T to favor quicker acceleration or use it as part of a gearing change to suit high-speed runs. Installation is straightforward, making it a good option for newcomers and experienced tuners alike.
Gearing Down Was Smart
Switching to a lower gear on my Rustler was the smartest move for bashing around my big gravel driveway and yard. Now I need a wheelie bar on concrete, plus the battery lasts a lot longer. The motor does heat up if I run too long in the grass, but for most runs, it's cool enough to touch. I got a new 90T spur gear but stuck with the original 86T. FYI: When you're adjusting the pinion back to the spur gear, tighten the adjustment screw so it moves with just a bit of force. Let it sit against the spur gear, then back it off just a smidge. If you don't, the gear noise gets louder and I'm guessing it wears out the spur gear faster.
