The Arrowmax AM-180018 bundle includes eleven aluminium pinion gears spanning 32T to 42T, giving a clear set of steps for adjusting drivetrain ratios. This spread allows racers and club drivers to dial in gearing for traction and speed across different surfaces.
These pinions are CNC finished from aluminium to keep mass low while maintaining strength. With a 48DP tooth form they are compatible with a wide range of RC spurs and gearboxes, offering straightforward installation for many models.
The supplied caddy holds the full set securely and protects the teeth from knocks and debris. It is designed to help keep spares organised so you can swap pinions quickly between practice runs or races.
