If you want finer control over gearing, the Arrowmax AM-180016 delivers a broad selection of aluminium pinions for RC cars. The kit includes 28 pinions from 21T to 48T, all 64DP, each machined for consistent tooth profile and reliable fit. A compact caddy keeps each gear organised so you can swap ratios quickly at the bench or track.
Arrowmax has a strong reputation among racers and weekend tuners alike. These aluminium pinions reduce rotating mass compared to steel, helping the drivetrain respond quicker while still offering good durability under normal racing conditions.
This set is ideal for drivers who dial in gear ratios frequently to suit track layout or surface grip. From tight technical circuits to higher speed layouts, having tooth counts from 21T to 48T makes it easier to balance acceleration and top speed.
