Four axes of professional grade motion. The DOF Reality P4 adds a heave actuator to the P3's pitch, roll, and yaw, bringing vertical motion into the experience. Kerb strikes arrive as physical impacts through the seat. Runway seams register on touchdown. Suspension compression under heavy braking pushes you down into the cockpit. The axis that connects you to the surface you are driving or flying over.
Professional grade throughout: 75 cm/s speed, 28 Nm torque, and 200kg capacity. SFU smooth gearing standard on all axes. Whether you are running endurance stints in iRacing, flying ILS approaches in MSFS, or training helicopter hovering in DCS, the P4 handles all of it without swapping configurations or choosing between a racing and flight version.
Not included: Seat, steering wheel, pedals, monitors, and PC are sourced separately.

Already own a rig?
Add motion without replacing your cockpit
If you already own an 8020 aluminium cockpit, you do not need to replace it to get motion. SIMRIG actuator systems bolt directly to your existing frame and add 3DOF motion underneath your current setup.
Also available: ProSimu P3MP and P5MP mount underneath most cockpit frames with ultra-quiet operation.
Quiet operation matters?
Explore ultra-quiet alternatives for home use
If noise is a concern in your setup environment, our ProSimu range uses direct-drive actuators that never contact the floor during motion. No vibration through floorboards, no mechanical noise travelling through walls. Designed for home use where quiet operation matters.
Recommended: Motion Seat · T1000 3M · T1000 5M
Feel the road surface, not just the direction
Three axes tell you which way the car is moving. The fourth tells you what the car is moving over. Kerb strikes at Monza arrive as sharp vertical jolts through the seat. Rumble strips at Spa send a rhythmic pulse up through the cockpit. Suspension compression under late braking pushes you down into the seat before the corner even begins. Heave is the axis that connects your body to the track surface underneath the tyres.
The P4 runs that fourth actuator at the same 75 cm/s professional speed as the other three. Kerb energy arrives as a fast sharp impact, not a slow lift. Runway seams on touchdown register as a distinct bump, not a vague wobble. At 200kg capacity, the heave actuator delivers consistent vertical forces regardless of how much weight sits on the platform.
Turbulence that moves you, not just shakes your screen
In flight sim, heave is altitude. Thermal updrafts lift you. Turbulence drops you. Touching down on a rough strip sends impacts through the seat that match what your eyes see through the cockpit window. The disconnect between visual turbulence and a stationary seat is one of the biggest immersion gaps in flight simulation. The P4 closes it.
Helicopter simulation benefits most from heave. Hovering in DCS involves constant micro-corrections in collective that translate to small vertical movements. The P4 reproduces those vertical shifts in real time, giving you physical feedback on altitude changes that would otherwise only register on the altimeter. Combined with pitch, roll, and yaw, the four axes cover every force a helicopter generates during normal flight.
