Re: replace stock springs when adding lift?
It seems to me if you are going to go thru the work & expense of changing springs I would suggest changing to an 2" OME lift.
Spring & shocks/struts will give you a 3" lift with better ride & far more articulation than stock springs with rr lift.
OME HD Lift about 3"
