2-3 week lead time — all units are handbuilt to order.

Ever wondered what separates a good sim shifter from a truly great one? It's not just about how it feels — it's about how it's built. The original H1SQ brought authentic tactile feedback to sim racers. The H2SQ takes the next logical step, replicating the core mechanical principles of legendary race car gearboxes.

• Adjustable resistance, hand-tuned for perfect gate travel
• Precise shaft guidance minimizes mis-shifts under pressure
• Direct USB-C connection with 9th/10th sensor logic for zero input lag

Engineering

• True dual-rail design inspired by real race gearbox architecture
• Aircraft-grade aluminium and tensile steel construction
• Independent shafts with mechanical mode collar for dual operation
• Hall Effect sensors with lifetime warranty coverage
• Compatible mounting for all major sim rig platforms

True Dual-Rail Shifting, Perfected

Master every discipline with unparalleled authenticity. In H-pattern, two shafts move in unison for a slick, positive throw, while sequential mode locks the secondary shaft for a crisp, dedicated action. This is real gearbox architecture, brought to your sim rig.

A New Standard in Mechanical Certainty

Feel the difference precision makes. Our new Hex Drive and hand-tuned mechanism eliminate play, delivering a solid, confident engagement every time. Inspired by the legendary feel of Porsche and BMW gearboxes, the H2SQ provides tactile data you can trust.

Engineered for Elite Competition

At 4kg, this is a serious piece of motorsport hardware. Its full-metal construction is built for the rigors of professional training academies and is backed by a lifetime warranty for commercial use. Built for commercial training centres and trusted by Motorsport UK for driver development.
