Definitely call the manufacturer because sometimes a vehicle needs different size shocks for front and rear. When I put a lift on my CJ I ordered my 5000's for a 2 inch lift...Well for my CJ 5 I need a 3 inch lift shock in the rear for a 2 inch lift. Quadratec was very kind and quick about sending me the correct ones. Got the right ones in less than a week later!

Gun it and run it!
