If your car or truck needs a little lift in the front end consider the Mr. Gasket Rubber Coil Spring Spacer. Made from high density rubber, it increases spring height without compromising spring travel. This allows you to raise the front end of your vehicle for clearance, etcetera, and not unduly compromise ride quality. The 1 inch thick spacer provides approximately 1 inch lift. It has a U-shaped groove and a flat top that allows it to be installed at the top of the front coil spring. Dimensions of the spacer are 4 inch i.d. (inner diameter) and 6 inch o.d., (outer diameter) and it can be cut down or expanded for slightly small or larger springs.
