9. Rock Krawler's rear upper coil bucket bolts in place of the stock bumpstop. Once it's bolted in place, it needs to be welded to the unibody. Sometimes stitching the welds (instead of one, continuous weld bead) is a good idea on a unibody.
We ordered our Rock Krawler kit without shocks, and used a set of Bilstein 5150 shocks to help with the absorption. The Rock Krawler kit calls for a shock that is 11 inches (compressed) and 21 inches (extended) for the 4.5-inch setup. The 5150 is much like the Bilstein 5100, but with a small piggyback reservoir to float the piston that divides the oil and nitrogen in the shock.
