The top tube is 2x0.120-wall with four simple bends to wrap around the front end. We went with the larger-diameter tube since it looked better and is stronger on the fullsize Avalanche. A smaller 4x4 could get away with 13⁄4- or 11⁄2-inch tubing. Determine early what size tube you want to use, as buying a bender with a single die is cheaper than a variety of dies to start with.
