The HUDY 107153 collection supplies 18 precisely machined aluminum pinions, from 18T through 35T, providing a full spread of gear ratios for hobbyists tuning speed and acceleration.
Made from aircraft-grade duraluminum, each pinion balances low mass with strength. Produced on a specially modified precision gear machine, the pinions have tight tolerances that improve concentricity and reduce drivetrain friction.
Edges are chamfered and the pinions are run-in to promote smooth engagement. The uniform hardcoating protects the teeth and helps the gears retain their shape for consistent performance over time.
The set includes the HUDY Graphite Pinion Caddy to keep all 18 pinions organised and protected when transporting to the track or working on the bench.
