LOS242018 43T Spur

Losi LOS242018 43T Spur Gear

The LOS242018 43T Spur Gear is a genuine Losi drivetrain gear designed for compatible 1/8-scale electric buggy platforms, including the 8IGHT-E RTR series. It is mounted on the center differential and works with the motor pinion gear to transfer power through the drivetrain.

The 43-tooth design is used to balance acceleration and top speed, depending on the pinion gear setup. A smaller spur gear like this generally increases top speed potential while reducing torque, while a larger spur would do the opposite. Proper gear mesh between the spur and pinion is critical for efficiency, smooth operation, and preventing drivetrain wear.

This spur gear is typically made from durable molded material designed to handle high RPM and torque loads, but like all spur gears, it can wear or strip if gear mesh is incorrect or if debris enters the drivetrain.

Over time, spur gears can develop worn teeth, cracking, or rounding, which can cause slipping, noise, or loss of power transfer. Replacing a damaged spur restores smooth drivetrain operation.
