Arrowmax AM-180014 64DP Aluminum Pinion Kit 21T-37T  [AM-180014]

Complete Pinion Range for Precise Tuning

Arrowmax AM-180014 Aluminum Pinion Gear Set delivers a full set of 17 pinion gears from 21T to 37T in 64DP pitch, built for hobbyists who swap ratios regularly. The aluminium construction keeps weight low while providing reliable wear resistance, making it useful for both weekend practice and club races.

Performance Advantages of Aluminium Pinions

These Arrowmax pinions are precision machined to tight tolerances so each gear meshes cleanly with compatible spurs. The lighter rotating mass of aluminium helps reduce drivetrain inertia, which can improve throttle response and overall drivetrain efficiency when dialling in ratios.

Applications and Handy Storage

The 21T-37T spread suits a wide range of setups, from high-speed on-road layouts to more torque-focused off-road use. A compact caddy keeps each pinion organised and protected, so you can carry multiple ratios and swap quickly between runs.
