I'm not trying to discourage you from putting them on but be aware that the longer shackles will totally mess up your castor, camber and toe. Since castor and camber aren't adjustable you need to add axle shims to rotate the axle housing to bring the axle geometry back. Even after that the truck still handled like crap. I had toe set to factory specs and the least little imperfection in the road caused the truck to act very unpredictable. Never did manage to get it so I felt comfortable driving it so I ended up going back to standard shackles. It can be done but it definitely isn't a straight bolt on and drive affair. Good luck if you go down this road.
