Now available, is a new high tech shock system for your Hummer. This system allows the driver to adjust the front and rear shocks independently for highway, off-road, rocks, sand, washboard, rock crawling, or to combat heavy pay loads and towing. The Adjustable Shock System has a manual knob on each shock that allows the driver to set the damping of the shocks independently from each other. You will be able to adjust your ride from "luxury soft" all the way to a stiff "sports car" ride, or anywhere in between. You select the ride that suits your driving conditions. Great for all driving conditions! Each shock is developed to withstand years of rugged Heavy Duty Hummer use.
