Abstract
A compression adjustment mechanism for a shock absorber includes a screw cam which is screwed into a bore in the endcap of the shock absorber and which abuts the spring seat for the compression or blow off valve spring. Tightening or loosening the screw cam, relative to the endcap, causes the preload of the compression valve spring to increase or decrease, thereby increasing or decreasing, respectively, the compression forces in the shock absorber. The compression adjustment mechanism can act on the spring seat from any direction, thereby eliminating the need to selectively orient the working cylinder and compression head assembly to the outer cylinder and endcap assembly during assembly of the shock absorber.
