I have never lifted a vehicle before so looking for info.
Looking to possibly adding a 2" - 3" body lift to the '07 Suburban. The purpose is to get the front up a bit as the '07 'Burbs ride a little low up front. The truck is 4 x 4 but, not for mudding, rock climbing or anything like that.
The purpose of the 4x4 is driving on dirt country roads ands in my pastures (or others) during bird hunting season etc.
I do not feel a suspension lift is necesary as I will not be adding any big boy mudders. At the most I will add 20" wheels and appropriate tires.
Body lifts are the worst mistake anybody has ever made. They raise the body off the frame, giving it leverage in a collision, and I have seen trucks that in a minor accident came apart. On that truck, it may also interfere with the airbag system. On top of that, the front will still sit about 2" lower than the rear.
If you just want to level the truck, there are 2" coil spacer kits to do just that, not the best solution, but way better than a body lift.
Here's what I am talking about: http://cgi.ebay.com/ebaymotors/07-Ch...QQcmdZViewItem
Thanks...That's what I need to know...'cause I don't know nuttin' except that I want to get the nose up a couple of more inches. What do coil spacer kits entail and what will I accomplish and / or harm?

I've got something similar to that in the back of my '78 T-bird. They were a snap to put in and don't affect the suspension travel at all. I only used 1" spacers and it raised the rear end about 2" so don't get too carried away. The amount you lift the frame off the axle will be less than how much the bumper moves up. There's probably a geometry whiz around that will be able to explain that more. 2" spacers will probably raise the front end up around 3" or so.
Actually 2" spacers up front likely will only give you 2" of lift due to the weight of the engine; any reputable manufacturer should be able to tell you exactly how much lift to expect. Another option which may be available to you is to swap out your present coils for 3/4 ton coils as they are heavier duty. I did this on my 73 F-100 and gained 1.75" while actually improving its handling. A body lift will not acheive what you wish tho I'm not against them; my F-100 is about to recieve a 3" lift to accomidate 31" tires.

Weight really has nothing to do with it. You're not changing spring rate, just adding 2" below the existing coil springs. The reason the bumper raises more is because it's further out that the axle itself. It probably won't change as much as the rear of my Thunderbird because it's not as far from the bumper to the axle as my T-bird is. 2" inch spacers might only lift the bumper 2.5" from where it is now. I'm sure there more to it than that. I know it depends on where the fulcrum is and all that. That's why I said someone else can probably explain it better. If you were changing the engine or adding some significant weight to the front, then I would agree that 2" spacers might actually net a 2" lift at the bumper. But just adding the spacers, you will see more than that.
