Precision Pinion Gears
Fine-tuning your vehicle’s gearing is one of the most effective ways to maximize performance from a brushless RC power system. Castle Creations offers precision pinion gears designed to help drivers dial in the ideal balance of speed, torque, and efficiency.
Our pinions are manufactured from high-quality hardened steel for durability in demanding RC environments. Available in a range of tooth counts and sizes, these gears allow hobbyists to adjust gear ratios for everything from high-speed runs to torque-heavy crawling applications.
Castle pinion gears are commonly used when upgrading to brushless motors, optimizing ESC and motor combinations, or tuning gear ratios in high-performance RC cars and trucks. Whether you’re chasing top speed or improving low-end control, the right pinion gear helps unlock the full potential of your RC power system.
Our Mod 1.0 and Mod .8 (32 pitch) have a 5mm bore and are used on our 1/8th scale motors for 1/8th scale vehicles, the Mod 1.5 gears with an 8mm bore for our 2028 motor and 1/5th scale vehicles. Our newest offerings include MOD1 8mm bore for 1/6th and 1/7th scale cars and 48 Pitch 5mm bore for 1/10th scale cars.
