HGT 6 speed gearbox
Our 6 Speed Gearbox is the best choice for Circuit Racing, Road Racing and Time Attack. The gears are straight cut strong and Diamond Ground to DIN5/DIN6 standards for maximum efficiency and even load distribution across the gear teeth. The gears use constant-mesh dog engagement for shifts as quick as 40 milliseconds. Probably the world's quietest straight cut geared, sequentially shifted, dog box transmissions, with almost none of the whine traditionally associated with this industry race standard. This gearbox is totally streetable, generates less heat than competitors and has been successfully tested behind engines with 1500hp/1100kw and 1600nm/1200ftlb in race conditions.
