Overview
The Hot Racing 20T 0.5 Mod Hardened Steel Pinion Gear is a precision-machined drivetrain upgrade designed to deliver dependable, high-strength power transfer in 0.5 module RC gear systems. The 20-tooth count strikes a versatile balance between acceleration and top-end speed — a smart all-around choice for everyday driving and tuning.
Built from hardened steel with a black protective finish, this pinion outlasts and outperforms soft stock pinions in every way that matters. The 1/8-inch (3.2mm) bore is sized for motors with a 3.2mm output shaft, including the Hot Racing CSG182R08, and pairs cleanly with any 0.5 Mod spur gear.
