HPI Racing 18T (48DP) RC Pinion Gear - HPI6918

The HPI Racing 6918 18-tooth pinion gear (48DP) is a direct-replacement drivetrain component designed for HPI Racing electric RC cars that run a 48 pitch gear system. Pinion gears are a critical part of the drivetrain, transferring power from the motor to the spur gear, and using the correct tooth count and pitch ensures proper mesh and reliable performance. The HPI6918 is an 18T gear in the 48DP (diametral pitch) standard, making it compatible with HPI vehicles and other RC platforms that use 48 pitch gearing.

Key Features

• 18-tooth pinion gear designed to the 48DP (diametral pitch) standard for correct gear mesh
• Direct replacement for worn or damaged pinion gears on compatible HPI Racing electric RC models
• 48DP pitch is a widely used standard in 1/10 scale electric RC drivetrains, making this gear compatible across multiple HPI platforms
• Correct tooth count and pitch are essential for drivetrain efficiency — swapping to an incorrect pitch will cause premature gear wear or failure

Compatible With

• HPI Racing electric RC models specifying a 48DP pinion gear
• RC vehicles and platforms using the 48 diametral pitch gear standard
• Check your model's manual or existing pinion spec to confirm 48DP and motor shaft diameter compatibility before fitting
