5. The Pro Series 80 is a beast. At first we thought it would be tough to fit the axle under the Super Duty, but with a little factory crossmember trimming and a couple days mocking the axle under the truck, Beck Herring, the Watson's suspension engineer, got it to fit. It will articulate without interference. The tie rod, draglink, and Panhard bar shown here are mockups; the final components will be made of much stronger tubing material.
