04.5 Dodge Ram 4x4 and 04 Alpenlite Augusta ride height?

If your Ram is like my '04 2500 was, it has spacers that are about an inch and a quarter thick between the rear axle perch and the bottom of the springs. I removed the U-bolts and placed the spacer on TOP of the springs and reassembled the whole thing.

This lowered the rear of the truck an inch and a quarter at the axle centerline (where your hitch is), and a bit more at the tailgate.

I did exactly the same thing on my new 2013 Ram 2500. It took about an hour per side to do this.
