An adjustable shock absorber is provided that includes a body defining a cavity. A member such as a piston is disposed in the body and at least partially separates the cavity in two first and second fluid chambers. A port extends through the piston and fluidly connects the first and second chambers during damping. A deflection disc, typically several, are arranged adjacent to the piston and one of the chambers to at least partially obstruct the port. A flange member such as a washer is arranged in proximity to the deflection disc with the deflection disc arranged between the washer and the piston. The deflection disc bends about the washer, which acts as a fulcrum, to unobstruct the port. The washer has a first portion with a first radial width defining a first rate of damping and a second portion with a second radial width different than the first radial width defining a second rate of damping different than the first rate of damping. The deflection disc bends about the portion of the radial width that is in alignment with the port. Preferably, the washer is oval shaped. An adjustment member such as a knob selectively rotates the washer relative to the deflection disc between the first and second radial widths.
