Of course it doesn't hurt that the rear suspension is damped by 21/2-inch-diameter Bilstein 9100-series quadruple-bypass race shocks with remote reservoirs. Overkill? Heck, yeah! But we needed some serious hardware out back to keep up with the front suspension. JD Fabrication mounted the shocks on this simple bed cage, which bolts to the F-150's frame and still leaves room for the spare tire.
