BDH H2SQ SHIFTER

Product details

Dual-rail engineering with a dedicated feel in each mode

The H2SQ uses two shafts working together in H-pattern operation. In sequential mode, the secondary shaft is locked to create a dedicated forward-and-back action. This mechanical arrangement changes the movement of the lever as you select a different mode. BDH's Hex Drive and guided shift mechanism are designed to produce positive engagement with minimal play.

That makes the H2SQ especially appealing if your simulator library includes cars with different transmissions. You can build your cockpit around one shifter position, then choose the mode that suits the car rather than reaching for a different control.

H-pattern shifting for manual cars

The H-pattern mechanism provides eight selectable positions that you can assign in your simulator. Set up the gear layout and reverse input to match the vehicle and your preferred orientation. Pairing the shifter with a clutch pedal makes manual cars more involving: your hands and feet work together through acceleration, braking and gear selection.

For heel-and-toe practice, begin with comfortable pedal spacing and a lever position you can reach while keeping your back supported. Choose a familiar car and practise individual downshifts before combining several changes during a braking sequence.

Sequential operation for consecutive gear changes

When you select sequential mode, the lever operates as a dedicated upshift and downshift control. The H2SQ exposes separate sequential inputs for assignment in the game. This is useful when driving cars that use consecutive gear selection and when you prefer a lever to steering-wheel paddles.

Before changing modes, place the lever in neutral and follow BDH's selector-collar instructions. Check the selected mode and control assignments before heading onto the track, especially if you switch between cars during a session.

Resistance that you can tune to your preference

The thumb-wheel tensioner changes the mechanical shift effort. H-pattern and sequential driving may feel best at different settings, so take time to find a comfortable balance. A lighter setting can suit relaxed driving; a firmer setting can make each selection feel more deliberate. Avoid excessive tension and use the adjustment procedure in the manual.

The most useful setting is one you can operate consistently throughout a race. Compare adjustments over several laps and pay attention to reach, wrist position and fatigue as well as the resistance itself.

Substantial construction for a permanent sim racing cockpit

BDH specifies a 4 kg assembly with a machined aluminium chassis and high-tensile steel components. Self-lubricating bronze guides and engineered spring components support its mechanical operation. The supplied nylon gear knob can be replaced with a suitable M10 × 1.5 knob, subject to BDH's fitting requirements and weight limit.

Mount the shifter securely before judging its feel. Movement in the cockpit support can make a firm gear change feel less precise, so choose a mounting position with adequate support and enough space around the lever.
