[QUOTE="Squatting Dog, post: 230441, member: 1688"] According to Fox the "perch ring" (our term) is actually called by fox as "spring preload ring". By adjusting this "preload ring" up it puts the spring under more compression forcing the lower control arms down. And raising the front end of the truck which in turns puts the cv joint in near binding conditions at rest. Adding jumping, full lock turns with the "preload ring" raised to top notch causes the cv boot to be pinched as nd torn. I hope this make sense - if you are still with me then maybe this will help you understand that moving up a notch up on the spring perch compresses the spring that much more through its travel. This increases the spring rate which lifts the front of the truck. The shock is still the same overall length when fully extended but with more preload the shock at ride height it is more extended and this means the piston is a little further from the first bypass hole, thus making the dampening a bit softer. Not to confuse things but the internal bypass holes are still bypassing at the same rate as when the spring rate was softer. -Greg [/QUOTE]
