These sway bar brackets are meant to be used for applications with a rear super duty axle. They can be used with a wide variety of sway bars but I have found that a Ford Ranger sway bar like Adco 368 works well for either 37.5" wide rear frames or 34" wide rear frames.

3.75" center to center of the two bolt holes
1.0" from surface of axle to base of flat surface
4.5" overall length This should work with a variety of rear

This is for one pair of raw steel brackets, no hardware
