You get 3\/8\" thick A50 steel U-bolt plates with three spring-pin locations, matched 8.8 perches, four 5\/8\" U-bolts with hardware, and a pair of shock brackets. The components are sized to work together so you can set pinion angle, center-pin position, and shock mounts without piecing parts from multiple sources.\u003c\/p\u003e\n\u003cp\u003eFitment is for 2.5\" leaf springs with perches profiled for a 2.75\" axle tube and U-bolts measuring 10\" × 5\/8\" × 2-3\/4\". Many 28-spline 8.8 axles at this width came in Ford Ranger applications; verify your axle width, tube diameter, and spring spacing before welding. If your pack height or plate stack is taller, consider longer U-bolts to maintain full thread engagement and re-torque after shakedown.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: R1137\u003c\/li\u003e\n\u003cli\u003eFor 28-spline Ford 8.8 rear axle swaps\u003c\/li\u003e\n\u003cli\u003ePlates: 3\/8\" A50 steel with three spring-pin positions\u003c\/li\u003e\n\u003cli\u003ePerches: 2.75\" axle tube, 2.5\" spring width\u003c\/li\u003e\n\u003cli\u003eU-bolts: 10\" length × 5\/8\" dia × 2-3\/4\" width, with 1\/4\" washers and nuts\u003c\/li\u003e\n\u003cli\u003eShock brackets: 1.5\" ID\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eKit Includes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e(2) Leaf spring plates for 2.5\" springs\u003c\/li\u003e\n\u003cli\u003e(2) Perches for 2.75\" axle tube and 2.5\" wide springs\u003c\/li\u003e\n\u003cli\u003e(2) Shock brackets, 1.5\" ID\u003c\/li\u003e\n\u003cli\u003e(4) U-bolts, 10\" × 5\/8\" × 2-3\/4\", with 1\/4\" washers and nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eNote\u003c\/h4\u003e\n\u003cp\u003eConfirm axle width, tube diameter (2.75\"), spring width (2.5\"), and center-pin location before welding.
