Need to replace or upgrade the pinion gear on your Traxxas RC vehicle? This is the official Traxxas 6745 gear - it's a 32P 9T pinion gear designed to fit models like the Stampede 4x4 (but definitely check your manual to be sure). Traxxas has been the top name in ready-to-run nitro and electric RC for years, and they make their replacement parts to the same high standards. This gear is built from quality materials for lasting performance, whether you're fixing up your ride or doing some performance tuning. It's a genuine part, so you know it'll mesh perfectly with your existing setup. Perfect for keeping your truck running smooth or giving it a little extra pep. Great for hobbyists who want to maintain their Traxxas vehicle themselves. Keep a spare on hand for race day or just general maintenance - because let's face it, gears can wear out. Easy to install if you're familiar with basic RC maintenance. Get back to driving fast!
