HGT Sequential 6 Speed
7075-T6 Billet CNC'd Case
Straight Cut and Diamond Ground to DIN5/6 standard for maximum efficiency and even load transfer across the gear teeth. Constant mesh dog engagement for shifts as quick as 30 milli-seconds. Probably the worlds quietest straight cut geared dog box, with almost none of the whine traditionally assoicated with this industry race standard. You’ll be amazed how quiet this gearbox is (as in totally streetable) and just how cool it runs.

Our Gearboxes come standard with the GM Muncie pattern on the front mount, with bell houses to suit most popular race engines.
Whilst some say that “any old bell-house will work” or “I will buy one from my local guy – he’s cheap and cheerful”; this is one of the most critical parts in the whole drivetrain setup. The front and rear facing plates must be 100% parallel, centres must be perfectly aligned, bolt-holes must be drilled in exactly the right position and at exactly the right angle. Many so called “gearbox problems” are actually the result of a poorly built, machined or drilled bell housings. Misalignment of just 10 microns can be sufficient to cause premature bearing failure or abnormal shaft or internal wear. It’s simply not worth trying to “save a little” when there’s a sizable gearbox investment at stake. All HGT Precision bell housings are built to handle race loadings, are aligned perfectly and have the drillings in exactly the right place to make installation simple. As is standard practise in the race industry, you should index the bell to your crank and block to ensure everything is perfectly aligned.
