Part Two: Under The Truck
1a. The Street Scraper rear suspension is beefy. The parts are laser-cut from 1/4-inch plate like the front 'bag mounts, and the rear link bars are once again made from 1.5x0.120-wall DOM tubing. Note that the upper bars are triangulated to locate the rear axle from side to side and that they are shorter than the lower bars. This has good and not-so-good points. The good here is that the shorter upper bars allow you to retain your factory fuel tank, and that saves money. You won't need to go through the hassle and expense of installing a fuel cell to have a radically lowered truck. But, like most suspensions designed to lay a truck on the ground, there is a compromise between performance and practicality. The short upper/long lower bar configuration means that as the axle moves up and down the pinion angle will change. It's not the end of the world though, and unless you are into autocrossing, road racing, or drag racing, the only time you'll ever notice is when the truck is laid on the ground and the wheels are perched a bit farther forward in the wheelwell than normal.
