4-axis racing motion with added vertical realism for a more physical, believable driving experience.
Step into the next generation of racing simulation with the DOF Reality H4 HERO Motion Platform — engineered for drivers who want full-rig immersion with the added realism of a true fourth axis: Heave, or vertical motion.
Since 2014, DOF Reality has been pushing home and commercial motion simulation forward with innovative mechanics and proven reliability. The H4 builds on the HERO platform’s full-rig movement by adding vertical motion feedback that 3-axis systems cannot fully replicate.
Designed with 4 Degrees of Freedom — Pitch, Roll, Yaw / Rear Traction Loss, and Heave — the H4 translates racing telemetry into physical motion you can feel throughout your body. This helps simulate acceleration and braking transitions, weight transfer through corners, rear traction breakaway, curb strikes, road bumps, jumps, compression, and elevation changes.
Like other HERO platforms, the seat, pedals, wheel, and attached peripherals move as one synchronized unit. This full-platform motion approach keeps your inputs and body aligned for a cohesive, natural driving experience.
Using Sim Racing Studio (SRS) or compatible motion software, the system converts supported in-game telemetry into real-time physical feedback. This gives your racing setup a more dynamic sense of grip, weight transfer, road texture, and speed.
Constructed with commercial-grade metal profiles and tuned for smooth responsiveness, the H4 is an ideal choice for serious home users, sim centers, and drivers who want the added dimension of vertical realism without jumping to a full 6DOF system.

The H4 adds vertical heave movement to pitch, roll, and yaw / traction-loss motion, giving racers a deeper physical connection to the car and track surface.

A. Yes. The H4 is a full-platform motion rig, meaning the seat, wheel, pedals, shifter, and attached accessories move together in harmony instead of only moving the seat.
A. The H4 adds a fourth axis: Heave, or vertical motion. This lets you feel vertical forces such as bumps, curbs, compression, jumps, terrain impacts, and elevation changes with greater realism.
A. Yes, but console support depends on the specific game and connection method.
Consoles operate within closed and proprietary platforms. Only select games send motion data from consoles using UDP over the network, such as Gran Turismo 7, Gran Turismo Sport, Project CARS, Project CARS 2, Assetto Corsa, F1, Forza Motorsport 7, and Forza Horizon 4 and 5.
For supported console games, a MagicBox solution may be required. For the latest supported PC and console games, please refer to DOF Reality’s supported games list or contact us before ordering.
A. Your seat setup comes down to personal comfort and driving style. The H4 Motion Platform supports many bottom-mount car or gaming seats, giving you flexibility to choose what feels best.
A bucket-style racing seat is recommended for added stability during high-intensity motion. A 4-point or 6-point harness can be added for extra security, though it is optional. For best performance, choose a lightweight seat so the motion platform can react faster and more precisely.
For convenience and easy adjustment, a standard bottom-mount car seat with sliders or rails is a practical choice. If you choose a bucket seat, you may need side-to-bottom bracket adapters and slider rails.
Seat Mount Dimensions:
A. Some assembly is required upon arrival. To ensure safer and more convenient delivery, the unit is typically shipped in separate boxes. Assembly allows you to configure the platform around your preferred seat, wheel, pedals, and cockpit layout.
A. No. The H4 arrives as a motion platform only. Seat, wheel, pedals, shifter, displays, PC, simulator games, and other accessories must be supplied separately.
A. You receive the complete motion platform system with the core structural and motion components required for setup. The unit is tested before shipment and packaged for safe delivery in manageable sections. After assembly, install the included motion software on your PC, connect the controller via USB, and configure your controls to begin racing.
All necessary hardware, cables, and basic tools are included for setup.
A. It is considered quiet for a motion rig. Actuator noise is generally minimal, with cooling fans and mechanical movement being the main audible elements. Actual sound can vary depending on motion intensity, flooring, room acoustics, and mounted accessories.
A. Allow approximately 3–5 hours for full installation, including hardware mounting, wiring, software setup, and calibration. Actual setup time can vary based on experience and accessories.
A. DOF Reality motion simulators are compatible with major VR headsets, but combining motion simulation with VR requires a few setup considerations. When the platform moves, your head and headset move too. This can cause the headset sensors to interpret platform motion as real-world movement, slightly shifting the in-game view.
If you notice excessive camera movement or “swimming” effects, start by reducing the platform’s motion intensity in your software settings. This often provides a smoother experience.
If additional correction is needed, motion compensation software can be used. Motion compensation typically uses a tracker or controller mounted directly to the platform to remove the platform’s motion from the headset’s view.
A. Motion compensation can work with both outside-in and inside-out tracking systems, depending on your hardware and software setup.
For base-station systems, users often mount a Vive Tracker or compatible tracker directly to the motion platform. For inside-out systems, some users mount a compatible controller to the platform where the headset cameras can see it.
A. Some VR users use hardware-based workarounds, such as mounting a sensor or controller directly to the motion platform or limiting certain headset tracking inputs. Results vary by headset, software version, and simulator setup.
For best results, use a stable tracker mounting location, reduce unnecessary vibration, and test gradually with lower motion intensity before increasing motion strength.
