Abstract: An adjustable strut spacer includes two complementary strut spacer disks that engage each other and the vehicle suspension to provide adjustable spacing. Each strut spacer disk is flat on one side and stepped on the other side. The steps of the upper strut spacer engage the steps of the lower strut spacer such that when the strut spacer disks are counter rotated the thickness of the adjustable strut spacer changes.

Abstract: A hybrid spring extender is composed of a spring cup bonded to a urethane or polyurethane spacer. The spring cup is metal and may include one or more mechanical elements to secure the spring cup to the polyurethane spacer. The hybrid spring extender is installed between the spring and the frame element that normally secures the spring to increase lift, or the height of the vehicle frame from the pavement. The use of a metal spring cup protects the polyurethane from deformation, dissipates heat and spreads the load from the spring to the entire polyurethane spacer. The combination of metal spring cup and polyurethane spacer also minimizes noise and rotational forces on the spacer.
