"We can appreciate the luxury of making easy ride height adjustments at all four corners of our JK. As delivered from Chrysler, this particular JK sat low on the passenger side when the fuel tank was full and it is also fair to assume that our coil springs will eventually settle in one area more than another. These real world conditions are where the ACOS Pro really shines. Adjustments up to 2-1/4 inches can be made without removing suspension parts from the vehicle. A floor jack and socket wrench are all it takes to regain an even ride height."
