TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
if you are really interested in taking the shackle hangers off the frame and putting a lift on, then i would suggest looking into longer springs in the front/rear. you can upgrade to 52" springs in the front, (http://diy4x.com/cart/index.php?route=product/product&path=24&product_id=120) and 56" springs in the rear using the diy flip and switch. (http://diy4x.com/cart/index.php?route=product/product&path=24&product_id=112) i am not sure how much lift this gains you, and you might have to get some zero rates to recenter the axle afterwards.
