How low can you lower a 4WD GMT900?
I have a 2007 Silverado 4WD that is currently lifted about 7" and I'm looking to go big power with it in the future so I'm debating on lowering it instead....how low can a 4WD NNBS go? I've heard 5/8 is the limit until the CV Axles limit anything lower than that. Does anyone have experience doing this? Mcgaughy's sells a 4/7 kit for them but I want to be lower than that.

It doesnt matter if it's a street truck or a track truck, how low it is will still matter for all the parts of the truck to work correctly.
3-4in the front is about the max you want to go to keep the CV angles good and prevent vibrations and possible breaking an axle shaft. Drop spindles and drop struts/coil relocators should get you there. The rear can be 5-7in, you really just have to get the driveshaft angle good for no vibration problems. Depending on how low you go will determine the look and you might get a reverse rake.
Tire and wheel size will also change the stance, so picking the drop and wheel size goes a long way.

What did you use to get to 5/8?? Spindles and struts?
