I have a 2" or 2 1/2" leveling kit....cant remember which and i have rancho shocks that are normal factory sized. Could i put shocks that are 2" longer in? Would there be any problems or advantages to doing so? The reason i ask is its almost time to replace the shocks and i thought that since its raised two inches that i should go ahead and put shocks that are 2" bigger in it and it would be better.
