The cross members are built from ¼” steel plate and have integrated differential mounts that work with the new provided differential mounts to properly reposition the front differential for optimal CV and front driveshaft angles. The whole package is protected by a new belly pan skid plate that runs from the front to rear crossmember and allows integration with the factory front skid/splash guard. The factory front struts are retained with the kit utilizing top strut spacer and preload spacer to gain the proper lift height.To lift the rear, BDS supplies multiple lift block options with 3” and 4” sizes available as well as longer u-bolts, 5500-series shocks, and all the necessary brake line/wire relocation brackets. This system allows for up to 35×12.50 tires to be installed on 18×9 or 20×9 with 4.5” backspacing.In addition to the 6” system, BDS is proud to also offer a complete 4” system as well.
