Thumbnail Filmstrip of F100 3 Inch Lowering Beams (1965-1979) Images
These King Pin I-beams drop the front of your F100 3 inches. They fit all F100′s from 1965 to 1979 and it doesn't matter if you have drum or disc brakes. If you have drum brakes and you want to upgrade to discs (very popular) all you have to do is use the disc brake spindle and king pins with these beams and away you go. They come with tie-rod extenders to keep your tie rods properly centered in the radius arms just like stock height and a custom wrench to ease the installation!
Caution: If you try to lower I beam trucks with springs you get trouble, if you heat or cut your springs, even if you use a "lowering" spring, you cause alignment issues you just can't correct out!
