Sigma Integrale DK2+ is a professional-grade motion system designed and manufactured in California, providing 2 inches (50mm) of travel across pitch, roll, and heave axis. Free from preprogrammed artificial or exaggerated effects, it replicates chassis movement, road surface texture, elevation changes, weight transfer, and loss of traction with precise, telemetry-based feedback, rapid response, and minimal latency. Each actuator uses a billet aluminum housing with a 2-inch (50mm) nickel-plated solid steel piston, rated for 800 lbs (363 kg) of total payload and 7.9 in/s of actuator speed at 1.5 N-m of motor torque. Actuators measure 14.75 inches tall by 3.375 inches wide and weigh 16 lbs each, mounting to standard aluminum extrusion chassis tubing, with extended brackets available for wider-slot profiles like Sabelt and Trakracer. The system runs on Sigma Integrale's in-house motion controller, built on a 32-bit real-time ARM processor and a custom 75-volt DC electrical system for compact, high-torque motors and thinner cabling. The system requires no lubrication and is built for years of maintenance-free operation, backed by a 3-year electrical and 1-year mechanical warranty. Built primarily for professional drivers, sim racing centers, and automotive manufacturers, it combines exceptional fidelity with proven reliability.
