Add the missing piece of true immersion to your simulator with a seat belt tensioner bracket designed to deliver real harness force feedback. A seat belt tensioner transforms sim racing and simulation driving by applying physical load to your body—so braking, acceleration, cornering, bumps, and drivetrain events feel far more lifelike than visuals and audio alone.

Compatibility

• Suitable for all Trak Racer and Non-Trak Racer simulators (excluding TR5 and TRF)
• Compatible with simulator cockpits using seat brackets and/or seat slider rails
• Installs easily under seat brackets/rails for a clean, rigid under-seat mount
• Compatible with Qubic System QS-BT1 Seat Belt Tensioner

Why Add a Seat Belt Tensioner?

A seat belt tensioner for sim racing adds “body load” feedback—one of the most important cues in real driving and flying. Instead of only feeling forces through your hands and feet, a harness tensioner loads your torso like a real car, truck, or aircraft would. This improves immersion, consistency, and control by making weight transfer and momentum easier to sense.

• Braking & deceleration – feel the harness tighten under heavy braking for more confidence and consistency
• Acceleration & throttle load – sense launch and pull under power for more realistic momentum cues
• Cornering G-force – experience sustained load through the harness to better judge grip and balance
• Kerbs, bumps & road texture – add physical texture cues that complement haptics, bass shakers and motion
• Gear shifts & drivetrain events – feel sharp, responsive harness feedback during shifts and load changes

Built for Racing, Flight, Truck & Farm Simulation

Seat belt tensioners aren’t just for motorsport. They are widely used across multiple simulation categories because they simulate momentum and load without requiring a full motion platform. This bracket is ideal for:

• Sim Racing – GT, Formula, rally, endurance racing, drifting, esports, motorsport training
• Flight Simulation – turbulence cues, pitch/load changes, aviation training and cockpit realism
• Truck Simulation – heavy vehicle braking load, road feel cues, long-haul realism and driver training
• Farm Simulation – terrain feedback, machinery momentum cues and operator immersion
• Commercial & Professional Training – simulator centres, coaching, fleet and aviation training environments

QS-BT1 Performance Feel (When Used With This Bracket)

Experience every braking, cornering, and gear-shift force like it’s real. The Qubic System QS-BT1 dual-channel direct-drive seat belt tensioner delivers up to 400 N of responsive force, enhancing your simulator with lifelike G-loads, engine vibration cues, and road texture feedback. Mounted on this precision-engineered bracket, the system stays rock-solid so forces are delivered cleanly and consistently.

Rigid, Clean Under-Seat Mounting

Manufactured for strength and stability, this bracket mounts under your existing seat brackets or slider rails, helping maintain seat adjustment while providing a firm foundation for consistent belt tensioner performance. It’s a clean upgrade path for anyone building a high-end sim racing cockpit or flight simulator rig.
