HPI Racing 20T (48DP) RC Pinion Gear - HPI6920

The HPI Racing HPI6920 20T Pinion Gear is a 48DP pitch pinion gear designed for use in HPI Racing electric RC cars and compatible 1/10 scale electric drivetrains. With 20 teeth and a 48 pitch specification, this pinion gear is a direct-fit option for vehicles running a 48DP gear mesh, making it a go-to spare or gearing alternative for HPI electric models. Swapping pinion gears is one of the most straightforward ways to adjust the gear ratio on an electric RC car, affecting the balance between top speed and torque to suit different tracks or driving styles.

Key Features

• 20-tooth count with 48DP (diametral pitch) specification for use in 48DP gear systems
• Designed for HPI Racing electric RC models compatible with 48DP pinion and spur gear combinations
• Part number HPI6920 for direct identification when ordering as a replacement
• Allows gear ratio tuning — a smaller pinion delivers more torque; a larger pinion raises top speed
• Machined to fit standard motor shafts used in compatible HPI electric drivetrains

Compatible With

• HPI Racing electric RC models using 48DP gear pitch
