Ok, so far I only found the Maxtrac shackles, hopefully they will give 2" of lift. The rear is sitting like 3-4" lower right now.
Lift kit and level installed...now the rear is about 3-4" lower than the front

 

Wait, you don't have a 4" or 6" block in the back ?

 

Do like tech said and get bigger blocks for the rear. That's a lot of rear rake you have going on

 

No, that's the problem. My truck had no factory stock block. The kit came with 2" blocks, but I knew that was no where near enough(because I knew I was gonna keep the level on in the front). However, I didn't know if it was safe to put a 4-6" block in. So I'm either gonna buy the skyjacker leaf pack to give me 4", or I'm just gonna swap out the 2" block for a 4" block, and use the lift shackles from Maxtac to compensate the rest
