Shock Valving Shims

4 of 36
Shock valving shims come in different diameters, and varying thicknesses. The widest shims are usually assembled directly against the piston, and smaller shims get stacked progressively on top. Shock valving shims also come in different thicknesses. The thicker the shim, the more energy it takes to deflect it. Most changes in shock valving are done by changing the number, arrangement, and thickness of the shims.
