Abstract
A method of making the load height of a suspension coil spring more consistent uses different sized isolators to make a combined spring and isolator height more consistent. The isolator or isolators may be attached to the top or the bottom, or to both the top and bottom of a spring. The load height of a spring is measured. Isolators of varying heights are attached to the springs to achieve more consistency in the overall load height.
