Ford 8.8 Rear Axle Simple Swap — 28 Spline
Basic swap kit with plates, perches, U-bolts, and shock brackets
This kit supplies the essentials to mount a 28-spline Ford 8.8 rear axle under a leaf-spring rig. 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.
Fitment 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.
Key Features
- Part Number: R1137
- For 28-spline Ford 8.8 rear axle swaps
- Plates: 3/8" A50 steel with three spring-pin positions
- Perches: 2.75" axle tube, 2.5" spring width
- U-bolts: 10" length × 5/8" dia × 2-3/4" width, with 1/4" washers and nuts
- Shock brackets: 1.5" ID
Kit Includes
- (2) Leaf spring plates for 2.5" springs
- (2) Perches for 2.75" axle tube and 2.5" wide springs
- (2) Shock brackets, 1.5" ID
- (4) U-bolts, 10" × 5/8" × 2-3/4", with 1/4" washers and nuts
Note
Confirm axle width, tube diameter (2.75"), spring width (2.5"), and center-pin location before welding. Use the three pin holes to fine-tune wheelbase, set pinion angle during mock-up, and torque U-bolts evenly in a cross pattern. Re-check torque after initial miles or trail use and verify shock clearance through full travel.
