***PLEASE READ***
can we keep the "why lower a 4x4", "I don't get it" or "what a waste of a truck" out of this thread? If you don't like it, think its dumb or whatever, then stay out of here. This is for the people who WANT to. Thank you.

For the SUVs the front is done the same way as a truck, what differs is the rear. Ground Force seems to have a good selection of lowering kits for the SUVs. Kits vary from a 2.5" to a 3.5" rear drop. Most kits should be around $480 or more.

McGaughys drop kit for SUVs. Note that with spindles you will need 17" rims or bigger.

McGaughys has some things for the 4wd/AWD trucks there. Note that with spindles you will need 17" rims or bigger.
If you want to just get the truck as close to a "level" stance is possible by lowering, you can buy the 2wd U-bolts (P/N 15002781) and take out the rear lift blocks and replace the 4wd U-bolts with the 2wd U-bolts. This should drop the rear about 2" and be pretty damn close to level. Pretty cheap and fairly quick to do.

McGaughys is the way to go IMO. The most they offer is a 3/5 drop. The front consists of spindles and lowering keys. For the Spindles you will need 17" rims or bigger. Prices vary from $309-$599 + shipping.
The rear of a 4x4 is no different than a 2wd truck, so if you want to go with something other than McGaughys for the rear, go for it.
The following info is specifically for the trucks, and more so for 1500HD/2500LDs
For those of you who will NOT be towing/hauling: All you'll need to do is trim the bump stops. Even with mild towing/hauling applications this will be ok. The only worry is that you might possibly bottom out from time to time.
For those of you who WILL be towing/hauling every now and then: You're going to want the Air Over Leaf (AOL) kit. The AOL is from Air Ride Technologies. If you go to the link you'll see they're rated at different loads. If you have a 1500HD/2500LD you'll probably want the 4000lbs-kit. But depending on how much you plan to tow/haul will determine which kit you'll need/want. Prices from $250-$325 + shipping.
For the AOL kit you don't need a compressor. Although this may seem janky, if you only need them every now and then this is good. Simply run air lines and have a remote fill plug for each bag. Then whenever you need them just pump them full of air. Otherwise Air Ride Technologies should be sufficient.

So far on the 2007+ trucks/SUVs the only thing I have gotten confirmed is that McGaughy's 2" Drop Spindles will work on 2wd/4wd/AWD. McGaughy's. As far as the rear drop goes, its going to be the same as a 2wd drop.
If anyone comes across any new info pertaining 2007+ 4wd/AWD trucks, whether it be spindles from another company, or coils working, please either post in the thread or PM me so that I can add it to the list.
