45# Steel 15T Pinion Gear 0.8 Mod For Arrma 1/10 & 1/8 Scale RC Cars - Senton Granite Big Rock Upgrades

About This Product

If you're into RC cars and want to upgrade your Arrma vehicle's performance, this 45# steel pinion gear is exactly what you need. The 15-tooth count with 0.8 module and 32 pitch is specifically designed for Arrma's 1/10 scale models like the Senton, Granite, Big Rock, and Vorteks 3S BLX, plus the 1/8 scale Typhon and Vendetta. What's really impressive is the 45# steel construction - it's about 30% harder than standard gears, which means it can handle the power of brushless systems without stripping or wearing down quickly. The CNC machining ensures perfect fit and smooth operation right out of the package. I've installed this on my Granite, and the difference is noticeable - smoother power transfer and no more worrying about the gear stripping during hard runs. The 3.175mm bore fits standard motor shafts perfectly, and installation is straightforward if you're familiar with basic RC maintenance. Whether you're looking to fine-tune your gearing for better speed or torque, or just need a durable replacement for a worn-out stock gear, this pinion delivers professional-grade performance without the premium price tag. It's become my go-to upgrade for Arrma vehicles because the quality is consistently excellent and it actually holds up to aggressive bashing sessions. The precise manufacturing means you get smooth meshing with your spur gear right away, without any annoying whining or binding issues.
