RC gearheads, listen up - this Protek steel pinion gear is exactly what you need for your high-performance builds. We're talking a 20-tooth 32P gear made from durable steel that can handle the power and RPMs of serious RC applications. The Mod 0.8 pitch is standard for many builds, and the 5mm bore fits most common motor shafts. But here's the really handy part - it comes with a 3.17mm reducer sleeve included, so you've got flexibility if your motor shaft is smaller than 5mm. The steel construction means this thing can take the heat and stress of aggressive driving without stripping or wearing down like cheaper brass gears might. Perfect for upgrading your basher, crawler, or any RC vehicle where you need reliable power transfer from your motor to your drivetrain. The precision cutting means smooth meshing with your spur gear, which translates to better efficiency and less power loss. Whether you're replacing a worn-out gear or tuning your gear ratio for better speed or torque, this Protek pinion delivers professional-grade performance without the professional-grade price. Keep a couple spares in your toolbox - you'll be glad you did when you're at the track or bash spot and need a quick gear change.
