Marty,
I would call the tech dept. at Pro Shock. They were very helpful with me when the rear shocks I had purchased through CRII were too long. Find the ride height you want, measure the distance between your shock mounts that you will be using. I think mine was 14" top mount to bottom mount. With 6" of travel you want 3" up and 3" down so when your just sitting the shock plunger is centered in the shock body. They have adjustable rebound S M F. Spring rate is 250. That is from memory so if Im wrong someone please correct me. But the tech should be able to tell you knowing what car you have. Good luck!
