The truck has the stock shackles and 3" body lift. But I'm not sure about the springs. It has sky jacker shocks, so im guessing it has a sky jacker lift. Could someone tell what size springs it has I think it has 3" but really dont know. The truck sits right now with the 35's here are some pictures. I want to get bigger shackles for the rear cause it sits 1 inch lower in the rear than the front. Are bigger shackles a good idea and what about the body lift it has on it already? I have pictures of the springs if needed. The rears have some arch to them but the front are really flat.

 

looks like 3" no blocks right? if you want a fast cheap way to fix sag , search zuk coil mod.

if you want a better way you can go with an add-a-leaf or a new set of trail gear springs or marlins or alcans or allpro.

 

Stock fender to top of 15" wheel is in the 13.5"-14" range, so measure yours and see:

Subtract the 3" body lift off and any extra height is your suspension lift height.

Longer shackles can give some lift:

Is it ok to use the shackles to level the truck out? and yes it does not have blocks
