@ram1500rsm is correct. When the weight of the truck is on the springs it’s still not maxed out on the strut. So the ride height is just shifted up. The way it works is unless you’ve maxed the strut out than you still are under stock compression. You just lose down travel. Most kits don’t recommend more than 2.5-3” lift or you start to kill your ride due to down travel and such. I’ve tested the lift and you can achieve 4.5-5” of lift on stock struts before you max it out on down travel. Hence the reason for only wanting 2.5” of lift max.if you started pushing 4-5” of lift out of the strut than you would be putting more pressure on the strut than the weight of the truck can push down on and would then cause the ride to be harsh and you would have no down travel. That’s why I’m only running 2.5” of lift on my struts. It’s a pretty simple concept. The weight of the truck and the preload setting only effect ride height because it sets a new lower point on your spring perch effectively changing your ride height by that much. If you compress the spring past the point where the weight of your truck can push down on it than that’s when you would have to add more weight to push down.
