Abstract: An adjustable length spring divider on a coil over shock absorber for a vehicle such as a car, truck or motorcycle. The effective length of the spring divider can be changed with the flip of a switch. The switch activates a piston on the spring divider alternating the piston between a collapse position and an extended position. When in the extended position, the spring divider is effectively longer therefore reducing the force and distance required to compress the springs to a point where the piston contacts the secondary stop on the shock body and reduces the number of springs being used by the shock absorber. The reduction in the number of active springs causes a switch from a lower, primary, spring rate to a higher, secondary, spring rate, where the spring rate can be defined as the amount of weight required to compress the shock absorber one inch.
