Perfect fit for a Ford 8.8 swap in your XJ. Will fit any size axle tube with slight modification. Just weld to your axle in the position to best suit your suspension and driveline. 3 laser cut holes in the plate allow you to position your axle forward, back or center in .75" increments for best axle location depending on your specific set up. Extremely strong .25" steel plate, laser cut and precision brake formed for excellent fit. Exact match to 3.18" axle tube diameter, but can be modified with minor grinding to fit any axle.
