Abstract
A shock absorber assembly includes a coil spring that reacts between first and second spring seats. The first spring seat is fixed to a shock cylinder and the second spring seat is fixed to a rod that is slidably received within the shock cylinder. An isolator is positioned between an end coil of the spring and at least one of the first and second spring seats. The isolator comprises an annular ring that defines a cavity that is at least partially filled with fluid. The isolator evenly distributes non-centered spring end forces through the fluid to reduce the effects of side load forces.
