Abstract
A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.
