This is the basic kit essential for a Rockwell Axle swap, more items could be added but this is the bare minimum, You will receive 1 pair of our 3/8" thick A50 Steel U-Bolt plates with 3 pin mounting options, a pair of our Rockwell Spring Perches with the same pin option to match, 4 - 10" x 5/8" x 3 5/8" Flat Bottom U-Bolts with 1/4" laser cut washers and nuts, and a pair of Shock Brackets. This will get your Roc's under the rig. BTW, this is NOT a Chinese made product that just can't hang with the big kids, this IS the Big Kid.
