NEW DOF Reality H4 System with SFU Gearboxes + Upgraded Reducer Motors

This full-motion platform provides four axes of movement Pitch, Roll and Yaw.

The H4 from DOF Reality is designed to deliver real physical sensations that home simulators were not able to provide before. It is the only at-home motion simulator offering true 4-axis movement, including Heave, allowing users to feel vertical G-forces, road bumps, turbulence, jumps, and changes in acceleration with high precision.

Built on DOF Reality’s experience in developing affordable motion simulators since 2014, H4 brings professional-grade motion realism into a compact and quiet platform designed for home use. The floor footprint is comparable to the DOF Reality H3 platform and measures 3 × 5.2 ft with a height of 2 ft (100 × 150 cm, 60 cm height), making it suitable for limited spaces without compromising motion performance.

The simulator is constructed from high-strength European steel for stability and long-term durability. All primary controls, including the seat, wheel, pedals, and flight controls, move together as a single unit, enabling accurate force feedback through body pressure points rather than visual effects alone. H4 integrates seamlessly with racing wheels, flight controls, and all major VR headsets.

Whether you are a sim racer, flight simulation enthusiast, or someone who wants to experience real motion at home, H4 delivers a level of physical realism that most home simulators cannot provide. This is motion you feel with your body, not something you simply observe on a screen

All Player1 Sim Gear DOF Reality sims include the new SFU (Standard Flange Unit) ball-screw gearbox upgrades which reduce motor loads and eliminate play in the gearbox providing smoother, more responsive motion.

The DOF Reality 'Pro' and 'R' models include the new Upgraded Reducer Motors which provide smoother performance for fine movements with no clogging at low speeds, perfect for Flight simulation use-cases.
