Currently I have a 5" block with 3/4 ton springs. I still have my stock 2" block in the shed and 1.5" zero rate I'm waiting to put in. If I got this right a shackle flip will net me 4", plus the stock 2'' block, plus the 1.5" zero rate, and a shim to correct the angles, should get me around a 2.5" of added lift to the rear? I'm thinking about maybe getting a 1" block instead of using the stock 2"er :shrug: I probably wont get a cowl hood anytime soon so I figured this would about even out with getting a cowl hood color matched and on the truck. Oh yeah, u-bolt reversal kit will be added too. Just a thought I was thinking about doing. Any input is appreciated greatly! I might not do is right away, but I just want to figure out some options. I got more important things I need to take care of first.
