Prior to the conversion, our donor Jeep had a 4-inch JKS J-Spec short-arm suspension system installed under it. The wheelbase was 94.5 inches. Notice the way the front of the rear fender flare mates to the black Poison Spyder rocker guards. The wheelbase after the conversion was 99.5-inches-a full five inches over stock. The setup is available for several popular aftermarket lift configurations, as well as for stock height applications.
