Performance, quality, reliability and value are what TT Industries builds its reputation on. This has seen TTI expand from a domestic business to a tough competitor in the international racing gearbox market.

The TTI sequential gearboxes are the lightest in the market for horsepower rating, are priced competitively and designed to perform. By engaging directly with driver’s mechanics and a selected number of specialist distributors, TTI is able to get rapid feedback, allowing staff to support drivers and installers effectively.

TTI imports high-quality steel from Germany to ensure a consistently high grade is used and all machine work is done in-house at the Nelson factory. Car castings are made in Auckland to specific designs and specifications and castings for motorcycle gearboxes are made in Australia. The TTI GTO sequential is the only New Zealand designed and manufactured car gearbox.

Founder, designer and TTI director Bruce Verdon says the company focus is on low costs for the consumer, reliability and strength, ease of installation, and being as light weight and efficient as possible.

“Sequential boxes are much quicker, and changing gears often gives you around a two-second lap advantage on most circuits, utilising straight-cut gears that are designed with large teeth to be as strong as possible, meaning better reliability. If you use the gearbox properly, it is so much quicker. It’s an absolute dream to drive a sequential,” Bruce says.
