DOF Reality H4 HERO – 4-Axis Universal Motion Simulator Platform (Racing & Flight)

The H4 Universal is the only at-home motion platform offering true 4-axis movement including Heave, letting you feel vertical G-forces, road bumps, turbulence, jumps and changes in acceleration with genuine precision — whether you're on the racetrack or in the cockpit.

This model can be used for flight and helicopter simulation as well as racing, with no compromise in any of them. The key advantage over the racing-only version is an additional gearbox on each motor, delivering extra smoothness for the slow, precise movements that flight simulation demands. If you want one platform that genuinely handles everything, this is it.

Where 3-axis platforms give you pitch, roll and yaw, the H4 adds a dedicated vertical axis — so the road surface or the turbulence itself becomes something you feel through your body, not just something you see on screen.

Since 2014, DOF Reality has been recognised as a pioneer in affordable motion simulators. Just like in a real vehicle, all controllers — wheel, pedals, joystick, yoke and monitor — move together with the seat, allowing g-forces to be simulated effectively through muscle pressure points. The highly customisable Sim Racing Studio software delivers precise in-game feedback based on telemetry, reproducing road bumps, surface texture, vibrations, turbulence, gear changes, collisions and more.

Frequently Asked Questions

Can I use this for both racing and flight?
Yes — that's exactly what this model is built for. The additional gearbox on each motor gives smoother slow-motion control, which suits flight and helicopter simulation, while the rear traction loss system keeps racing dynamics fully intact.

What does the Heave axis add?
Heave is vertical movement. It lets you physically feel road bumps, curb strikes, jumps and landings when racing, and turbulence, climbs and descents when flying — sensations a 3-axis platform simply can't reproduce.

Does it work with PlayStation and Xbox?
Yes. Select console titles — such as Gran Turismo 7 & Sport, Project CARS 1 & 2, Assetto Corsa, F1, Forza Motorsport 7 and Forza Horizon 4 & 5 — send motion data over the network. For these, the Console Link / MagicBox option enables motion directly from the console without a PC.

What seat should I use?
Seat choice comes down to personal preference — almost any bottom-mount car or gaming seat will work. A bucket racing seat is recommended to keep you secure during G-forces, and a lighter seat improves platform performance. The DOF Reality Simulator Seat is available as an option and includes sliders and all hardware.

Does it come assembled?
The platform ships disassembled in two boxes for safe transport. Assembly is a straightforward process and all required tools are included.

Please note: the platform is sold as a plug-and-play motion system. Seat, VR headset, and controllers (wheel, pedals, yoke, etc.) are purchased separately — the platform supports all of them. Add your preferred upgrades from the options above.
