D-BOX G3 4250i-3 Four Actuator Motion and Haptic System

For Users Who Want it All

The D-BOX G3 4250i-3 Haptic System is the choice for sim racers who want realistic motion, deep travel, and authentic physical feedback. With its 3-inch range and powerful full-body engagement, G3 brings you closer to the car than ever before — letting you feel suspension load, curb strikes, surface texture, and every weight shift with real-world clarity.

The Foundation of Your Sim

The D-BOX G3 4250i-3 is a four-actuator motion and haptic platform designed to sit directly between your cockpit and the floor. Each actuator replaces a standard rig foot, lifting the entire simulator — seat, wheel, pedals, and driver — into a unified motion structure. Rather than adding effects to a single contact point, G3 moves the whole driving position, so every force is felt across your body as it would be in a real car.

Realistic Feedback

Each actuator handles both large-scale movement and high-frequency vibration internally. There’s no need for external shakers, amps, or extra mounting hardware. Vertical travel delivers suspension movement, braking dive, and elevation changes, while rapid micro-movements convey surface detail, curb texture, tyre slip, and load transitions. Everything comes from the same hardware, which keeps the feedback coherent and easy to read at speed.

Software Setup That Matches Real Driving

On PC, the system is configured through D-BOX HaptiSync Center. From there, you select supported titles, adjust intensity levels, and choose how much motion and vibration you want from each driving cue. Profiles can be tuned per car and per sim, letting you run subtle feedback for training or sharper response for competitive sessions. The system responds to telemetry, not scripted effects, so what you feel is driven by the car’s behaviour on track.

Built for Long Sessions

The G3 line is engineered for sustained use, maintaining the same response over long practice runs and endurance races. Each actuator supports up to 250 lb, giving the platform the headroom needed for heavier rigs, direct drive wheels, and load cell pedals. Power delivery and thermal limits are managed to keep performance steady rather than tapering off mid-session.

Tuned to You, Not Locked In

Through HaptiSync Center on PC, the G3 system adapts to your preferences. Intensity, profiles, and behavior can be adjusted per car and per title, letting you dial in exactly how much information you want coming through the rig. Subtle when you’re learning, aggressive when you’re pushing — the system follows your intent.
