YEAMG-48021-026 Pinion Gear Super Hard Combo set (48P 21T-26T 6pcs )

Designed for 1/10 scale electric RC vehicles using 540 motors, this six piece pinion gear set provides multiple gearing options for fine tuning drivetrain performance. The gears are precision made from 7075 aluminum with a titanium hard coated surface for smooth and durable operation. The set includes 48 pitch pinions ranging from 21T through 26T, allowing racers to make small gearing changes for acceleration and top speed. Each gear uses a 3.17mm motor shaft bore and includes its own set screw. A compact carrying case is included for convenient storage and organization.

• Six Gearing Options: Includes 21T, 22T, 23T, 24T, 25T, and 26T pinions. This range allows racers to fine tune gearing without purchasing each size separately.

• 48 Pitch Design: All six gears use a 48 pitch tooth profile for compatibility with matching 48P spur gears. Proper pitch matching is important for smooth and reliable gear mesh.

• 7075 Aluminum Construction: The pinions are made from high quality 7075 aluminum for a lightweight yet durable drivetrain component. The material is well suited for competitive 1/10 scale applications.

• Titanium Hard Coating: A titanium coated surface provides a smooth finish designed to improve drivetrain efficiency and durability. This helps the gears maintain consistent performance during repeated use.

• 3.17mm Motor Bore: Each pinion features a 3.17mm bore designed to fit compatible 540 motor shafts. Verify your motor shaft diameter before installation.

• Individual Set Screws: Six set screws are included, with one for each pinion gear. This allows each gear to be installed and secured independently on the motor shaft.

• Includes Carrying Case: A compact case is included to keep all six pinions organized and protected. It also makes transporting different gearing options to the track convenient.
