Very strong, excellent fit, and cheat!! Can't beat the price. Was going to make my own out of flat plate, but for the price of these it would be dumb not to buy these. And because they're stamped, they are very strong

Was happily surprised how close the tolerances were for caliper mounting and how square it was sitting on the axle tube prior to welding it. Really like this bracket!ma
