What if my shocks were shot? Like 23 years old, never changed. Wouldn’t they have sunk a little? It’s not obvious, unless you compare. When I put the left front on (new Rancho), the right front (still stock) was lower. Same went for the back.
Shocks dampen movement. They do not create ride height. If you can compress a shock by hand, it is incapable of having any meaningful affect on the ride height on a vehicle with over 3000lbs of sprung weight.
