This is the basic kit essential for a 2.75" Diameter rear axle swap (D44) or spring over, 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 (for 2.5" springs) with 3 pin mounting options, a pair of our Spring Perches (2.5" wide with a 2.75" axle tube cutout) with the same pin option to match, 4 - 10" x 5/8" x 2.75" U-Bolts with 1/4" laser cut washers and nuts, and a pair of Shock Brackets. This will get your D44 Axle under the rig (if you found one of the more rare 3" tube D44's get the 3" kit). BTW, this is NOT a Chinese made product that just can't hang with the big kids, this IS the Big Kid.
