If someone told you that you had to strip your sled down and take it back to stock with the exception of 3 "add-ons" which you were allow to leave on the sled which 3 add-ons would you keep? i.e. bdx cool air kit or a 10.4 secondary or a Fox float suspension kit.. Remember you can only keep 3 the rest are gone. Oh, and you can't put anything on that wasn't already there.
