I used 2" lowering springs front & rear...wish I had gone more.
Lowering spindles give you 2-1/2" AND disc brakes, 5- OR 6-lug, depending on hubs you choose. As others say, this is the best because you keep geometry and travel. You can use lower springs, too, for the bumper-dragging look.
Rear, you're limited to springs, or completely changing everything. If you lower 4" or more, it is advised that you C-notch the frame for more travel. I like a little rake to the truck, so when loaded it doesn't "lean back".
Air bags are a common spring replacement, giving you adjustable ride height.
How much do you want to spend?
