Adding a spacer to the top of the shock assembly will result in excessive down travel of the front suspension.Just remember that while it is simple and inexpensive, adjusting to the mid-perch of the shock gets about a 1.5" lift on the Raptor, but you will end up with a stiffer ride overall, because you are compressing the spring and increasing the spring rate. By installing the ReadyLIFT 2" leveling kit or the T6 Billet kit you can receive a 2" lift in the front while maintaining factory ride as the extension goes above the strut. You could achieve a better ride, and lift with the leveling kit rather than making the mid-perch alone. Also, you would definitely want to stay away from trying to combine these two modifications as it would bind up your cv's. More info at: www.readylift.com
Excessive down travel adversely effects: upper control arm, spring, Spindle, upper and lower ball joints, inner and outer drive shaft universal joints.
Setting the OEM shocks to mid-perch has No effect on spring rate; it is the change in neutral position for the shocks piston that effects the ride quality; and in my opinion for the better.
