the thing about these ifs fronts is that there is no real cheap way to gain lift. you'll spend at least 1k when you're done for more than 4 inches. you can crank your front t-bar bolts for 2 inches of lift up front. just remember to keep the same number of turns on each side, and get an alignment after. as for the rear, don't do blocks. I did and it made my truck ride like ****. i'd use shackles or an add a leaf. that'll put you right at 2 inches all around easily for under $100. look into new shocks also if you find yours are maxxed out. I went with the gabreal max control shocks and I found that even though they are an o.e.m. shock they were good for 2 inches.
