GEARS

This gearbox is ideally suited for drift cars with a wide torque band. The gears are straight cut strong and diamond ground to DIN5/DIN6 standards for maximum efficiency and even load distribution across the gear teeth. Constant-mesh dog engagement for shifts as quick as 40 milliseconds. Probably the worlds quietest straight cut geared, sequentially shifted, dog engaged gearbox, with almost none of the whine traditionally associated with this industry race standard. This sequential transmission is totally streetable and generates less heat than competitors. Gears have been successfully tested behind engines with 1500hp/1100kw and 1200ftlb/1600nm in race conditions.
