Bending, cutting, measuring, welding, and many, many hours went into the rear suspension's lower links. All this careful construction is for good reason: They're highly stressed, and need to be both strong and tough. What's the difference? Strength refers to the ability to resist bending under loads. Toughness refers to the ability to resist bending or breaking under impacts, such as those received from rogue rocks that live in sand washes. Another of this truck's money-saving components is the Ford 9-inch rearend from a salvage yard. After it was brought back to the shop, the salvaged housing was filled with 5.67 gears, a spool, 31-spline 'shafts, and was capped off with Wilwood Superlite brake calipers. As with the Beer Can, the four-link nets 28 inches of rear wheel travel.
