This bracket is for Axle mounting, it is cut for a 3.0" Tube and at a 10 degree angle but we all know how to change that. You can also add or remove a few degrees offset with a couple minutes and that same tool. Made with the very common 2.625" (2 5/8) inner width. These are .25 HR P&O Steel Plate with an integral Bridge bent into the Bracket so you have no weld related stress risers to worry about. Drilled for .5625" (9/16) bolts but easily drilled to another size. Sold as pairs.
