I just saw in my owner's manual that plow prep'd trucks came with front air shocks. I am working on putting a plow on my truck and was concerned about the added wait, I have about an inch of space between the bump stop and the front end right now. What are good brands to look at? is this a good route to follow? are there independant air bag set ups for the front of these trucks? I was very happy withe the air bags in my 2 wheel drive, but they fit inside the coil springs... thanks for any input.
