What are DreamBeams? We experimented with different ways to build a strong accurate lowering beam you can just bolt on. We found the best result for your installation and performance needs was the DreamBeam design. Our exclusive tubular construction is the most accurate lowering beam anywhere. We use thick walled DOM tubing, nested, welded in the fixture giving you full alignment adjustment. The fabricated "I-beam" type parts suffer from "weld creep" as they are welded, which simply means they warp a little. That makes it hard to get consistent finished parts! You only need to remove the factory beams and replace with DreamBeams and you have a 3" drop with the factory coils, full suspension travel and all the goodness that comes with that!
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!
These King Pin beams drop the front of your F-100 3″. These beams fit all F-100′s from 1980 to 1981 with unequal length beams and using a king pin with a diameter of .8593"
