Losi Pinion Gear 18T Mod 0.5

Dial in your gearing with this genuine Losi Pinion Gear, cut with an 18-tooth count on a 0.5 Mod pitch and sized for a 2mm motor shaft. Pinion gears are one of the most important tuning parts on any geared RC vehicle, directly controlling the overall gear ratio between the motor and spur gear, which in turn shapes acceleration, top speed, and how hard the drivetrain and motor are worked on a given track or trail layout. Stepping up tooth count from a smaller pinion raises top speed at the cost of acceleration and can increase heat, so having the correct tooth count on hand lets drivers tune for a specific surface, battery, or motor combination. Manufactured by Losi to precise tolerances, this pinion mates cleanly with compatible 0.5 Mod spur gears and 2mm motor shafts, seating securely with a proper mesh that reduces gear noise, wear, and the risk of stripping under load. Because it is genuine Losi hardware, fitment and material quality match what the vehicle was engineered around, giving racers and bashers confidence that their gearing changes will be consistent and repeatable from one setup session to the next.
