Re: 3" lift.
Your best option would be the OME MD/HD lift. With the HD you can net right at 3" of lift and fit 32-33" tires with the pinch weld and rear fender mod. You can get it from Kolak for around 7-800 dollars. The lift consists of new springs, struts, and shocks. You won't need anything else. The lift is very good quality. I love the ride compared to stock. You can check out my garage for pics. Good luck with the lift!
