The Arrowmax AM-180018 kit contains eleven aluminium pinions covering 32T up to 42T, giving a practical range for ratio changes. This set is useful for anyone wanting simple, repeatable gearing steps for different track and surface conditions.
Manufactured from aluminium, each pinion balances lightness and strength. The 48DP specification ensures these gears mesh cleanly with compatible spurs, suitable for many modern RC drivetrains used in both club racing and recreational driving.
The included caddy secures each pinion in its own slot to prevent contact and damage. It makes it easy to carry the complete set to events and keeps the gears ready to fit when you need to change ratios trackside.
