Up front, the kit features diesel-specific Pro-Ride coil springs, heavy-duty tubular radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation hardware, brake line brackets, and precision-tuned shocks. A transfer case indexing ring and new transmission crossmember are included to allow continued use of the factory front driveshaft at this lift height. In the rear, the kit uses a high-strength steel lift block, a heavy-duty air bag spacer, longer U-bolts, and a matched set of shocks.
