Unity automotive delivers top of the line quality suspension parts made to insure a trouble-free installation and long-lasting reliability. The Elite Suspension Powered by Unity Solenoid Valves are designed to work with the electrical components of the air suspension system to fill the bellows to the appropriate height. Our solenoid valve unit functions as good as, and usually better, than the OE factory valve that came standard on the vehicle. Once you have installed your solenoid valve your rear air spring will once again work in unison and provide an ultra-smooth ride. The kit comes with 2 replacement air suspension solenoids.
