This 20‑tooth 32 pitch pinion gear is a short‑face hardened steel unit machined for precise engagement with 32 DP spur gears in RC drivetrains. Its reduced face width (“short” style) helps fit in space‑limited motor compartments and achieves proper mesh without interference from motor housing or chassis parts. The gear has a 1/8 inch (3.175 mm) bore that fits directly on standard motor shafts, and a set screw seats securely to maintain consistent mesh under load. Hardened steel construction and heat‑treated teeth resist wear and fatigue in high torque conditions compared to softer stock pinions. Accurate tooth spacing promotes smooth power transfer with minimal backlash and drivetrain noise. This type of pinion is useful for tuning final drive ratios to balance acceleration versus top speed on competition or basher builds. Installation involves seating the gear on the motor shaft, adjusting mesh with the spur gear, and tightening the set screw with a hex driver.
