Losi LOS3741 Pinion Gear 18T Mod 1.5

This 18-tooth pinion gear is engineered for the Losi 5IVE-TE platform and is machined from strong alloy steel to handle the high torque output of the vehicle's electric power system. It features a Mod 1.5 tooth pitch and is bored to fit an 8mm "D" profile motor shaft, ensuring a secure, slip-free fit during hard launches and sustained running. The precision-cut teeth maintain consistent mesh with the spur gear, which cuts down on drivetrain noise and premature wear that comes from a worn or incorrectly matched pinion. This part is a direct factory-spec replacement, so it installs without any changes to the motor mount or gearbox. Stepping up to an 18-tooth pinion from a smaller size raises the overall gear ratio for higher top speed, making this a useful option for owners tuning their 5IVE-TE's performance for open terrain. The alloy steel construction is built to resist tooth stripping under the repeated high-torque loads generated by large-scale electric power systems. Keeping this pinion on hand alongside other tooth counts allows for quick gearing adjustments to match track conditions, battery setup, or driving style.
