lowering

i want to level my truck "2 in front and "4 in back. has any one done this and do i need new shocks, or will lowering shackles work? i think it will look really good. any sugestions?

sounds like what you want is just a standard 2/4" drop. There are alot of manufacturers out there that make a kit to get the look you want. I personally went with DJM.

You could go 2" drop coils in the front and a 4" rear shackles/hanger kit in the back. I went with the replacement A-arms in the front for a better ride.

and yes you'll need new shocks

You will only need new shocks if you get coils or spindles, you can use the stock shocks in conjuntion with the control arms.:slap: :icon16: You will need lower shocks for the rear though.

I personally would go with the McGaughy's 2/4 kit. Their spindles are the best thing out right now. The guys on gmfullsize have done nothing but rave about the ride and quality of the kit. And having driven my friends truck with spindles(i have djm control arms) i prefer the spindles.
