Thats right, Outriggers! For a long time I have been trying to make the best possible way to outboard Leaf Springs or get that llittle bit more space on a frame to mount my links inboard, these are it! They are designed to rest under the frame and 2" outboard for a total of 4" width that adds a ton of strength also. The ends are boxed to give extreme rigidity and they also provide ramped ends so you don't snag on the rock your trying to go over. These are 1/4" thick and sold in pairs. This model has a 7" X 4.5" mounting area. This pic shows the 4.5" model, the 7" model is simply longer. You can see the smaller bends on the lower flaps that add strength and support to the platform on the sides of the frame while removing any hangup potential. Welding required!
