A shock absorber assembly includes a damping adjustment mechanism that can easily be incorporated into a twin cylinder design. The shock absorber includes an outer cylinder and an inner cylinder mounted within the outer cylinder. The inner cylinder is spaced apart from the outer cylinder to define a gap. A piston is mounted within a fluid filled chamber formed within the inner cylinder to dampen vibrations. Holes are drilled into the wall of the inner cylinder to provide fluid ports that can communicate with the gap to form a bi-directional fluid path as the piston moves back and forth within the chamber to dampen vibrations. To provide variable damping, the outer cylinder includes an eccentric inner diameter to outer diameter profile that allows damping adjustment between high and low damping forces. The damping force is adjusted by rotating the outer cylinder relative to the inner cylinder to vary the size of the gap with respect to the ports.
