ABSTRACT:
A suspension unit used in a pull type shock application is disclosed, whereby a main shaft passes completely through a damping fluid so that the shock absorber fluid is not compressed when the shock shaft is displaced. The shaft also acts on a compression spring by an additional piston on the shaft. A cylindrical outer housing provides two distinct air chambers. The pressurization of these air chambers alters the spring rate, preload of the suspension, and vehicle ride height.
