BDH H2SQ Dual Mode Shifter

BDH H2SQ Dual-Mode Shifter: Mechanical precision inspired by real-life racing

The BDH H2SQ redefines the standard for sim racing shifters with a truly mechanical dual-mode design. Developed through years of real-world competition testing, this sequential H-shaped shifter delivers an unparalleled driving feel, geared toward both professional training and ultimate sim racing immersion. A direct evolution of the acclaimed H1SQ, it now features a dual-axis system, industrial-grade components, and a fully optimized internal structure.

Advantages that make the difference in simulation

• True Dual Shifting : Switch between sequential and H-pattern modes with just a turn of the mechanical collar, no additional software required.
• Robust, metallic design : Made of aircraft-grade aluminum and high-strength steel to withstand intensive use.
• Realistic mechanical feel : inspired by real competition gearboxes (F1, rally, touring cars).
• Built to last : Ideal for simulation centers, pilot academies, and demanding home setups.
• Accessible maintenance : modular and compact design for easy replacements and adjustments.

Key features of the BDH H2SQ

• True mechanical dual axis : Improves accuracy and reduces backlash when shifting.
• Dual Mode (H-pattern and Sequential) : Switch between fitness modes with 100% mechanical feel.
• Selector collar with physical lock : activates/deactivates sensors and routes according to the selected mode.
• Hand-tuned mechanism : Individually calibrated for optimal resistance and travel.
• External USB-C connection : robust and accessible, eliminates common problems with internal PCBs.
• 100% metal construction : professional grade materials for maximum durability.
• Sequential Lockout : prevents errors in lateral shifts during intensive use.
• Compact and modular : easy integration into any cockpit or SIM platform.
• Motorsport UK Approved Authenticity – Used in real driver training programs.
• 9th/10th Channel Smart Sensor : Ensures full software compatibility in both modes.

Real driving sensation: to train like a pilot

The H2SQ isn't just a simulation component; it's a tool developed with direct influence from real-life gearboxes like those in the Mazda MX-5, the Honda Civic Type R, and the Porsche G50. Its mechanical architecture mimics the gear selection systems of racing vehicles, allowing not only for a more immersive experience but also for a precise and reliable muscle memory training tool.
