Losi LOS3743 Pinion Gear 20T Mod 1.5

This 20-tooth pinion gear is built for the Losi 5IVE-TE platform and is machined from strong alloy steel to hold up under the high torque loads generated by the vehicle's electric power system. It uses a Mod 1.5 tooth pitch and is bored for an 8mm "D" profile motor shaft, giving it a secure, slip-free fit during hard acceleration and sustained high-speed running. The precision-cut teeth keep mesh with the spur gear consistent, which reduces drivetrain noise and the premature wear that results from a worn or mismatched pinion. This part is a direct factory-spec replacement, so it installs without any modification to the motor mount or gearbox. Moving up to a 20-tooth pinion raises the overall gear ratio for higher top speed, a useful option for owners running the 5IVE-TE on open terrain where straight-line speed matters most. The alloy steel construction is built to resist tooth stripping under the repeated high-torque launches typical of large-scale electric drivetrains. Keeping this pinion on hand along with other tooth counts lets owners quickly adjust gearing to suit terrain, battery setup, and driving style.
