Arrowmax moulded pinion gears. Using an anti-slip golden-anodised aluminium hub and high strength anti-wear composites, the moulded lightweight design has been thoroughly track-tested to ensure the pinions will withstand the rigors of both on-road and off-road stock racing. Using the gears will improve overall drivetrain efficiency, throttle feel and power.

Uses M2.5×2.5mm grub screw and requires a 1.3mm or 0.050 hex driver.
