HGT Precision
HGT Precision's principle of no compromise on Quality, Consistency or Reliability has enabled our brand to build rapidly on a global basis. To ensure these non-negotiables are delivered, we invest in the best materials, manufacturing with premium quality European equipment with a talented and motivated team.
The Swiss are famous for consistency and high quality, which is why we chose Switzerland as our manufacturing base. Craftsmanship, exacting standards and a commitment to excellence are visible in every one of our hand-built billet CNC masterpieces. The factory is ISO 9001 accredited which means HGT Precision sequential gearboxes are made the same way, to the same precise standards – every single time.
GEARS
HGT Precision's 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. 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 and generates less heat than competitors. This gearbox has been successfully tested behind engines with 1500hp/1100kw and 1600nm/1200ftlb in race conditions.
