This is the basic kit essential for your 9" Rear 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 3" Spring Perches with the same pin option to match, & 4 - 10" x 5/8" x 3 1/8" U-Bolts with 1/4" Hardened washers and Ubolt Tallnuts, and a pair of Shock Brackets. This will get your new Axle 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.
