2007 Suburban 4x4 Performance Suspension
 

I have a bone stock 07 Suburban that I simply cannot stand driving. The thing sways all over the road, has a ton of body roll, cant handle curves, bumps or potholes at speeds higher than 75 and just feels sloppy and loose in general. All of the steering and suspension components are in good condition currently, and the alignment is spot on. Does anyone know of a GOOD suspension/handling kit for these things? Does not need to be bolt in, I can handle most fabrication needs. I just want the truck to ride like its on rails. I wouldn't object to lowering it either. I have a lot of plans for the engine and trans. But I don't want to start on that until I have a plan hammered out for the steering and suspension. TIA

is it lifted or anything?

No. It is currently completely stock.
