HGT PRECISION 6 SPEED SPECIFICATIONS

GEARS

Straight Cut and Diamond Ground to DIN5/6 standard 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. You’ll be amazed how quiet this gearbox is (as in totally streetable) and just how cool it runs.
