Poolman, Is this for the back of your toyota? Are you going to use a downy shackle or somthing in the rear? If you are or what ever you are using for rear lift call the company that makes the lift they will have shock strokes on there application guides... OR you can do it the hard way and take your leafs spring pack apart and stroke it with just the main leaf bolted in. You might need to chain the truck to the floor... or you might not get it to bump... Good luck... P.s. Your front shocks are on there way...They shipped friday..
