NOTE: SRW (Single Rear Wheel) models may require custom U-Bolts to accommodate factory tow package. Will not fit DRW (Dual Rear Wheel) applications without custom U-bolts. Towing Capacity will be reduced with the installation of this kit.
NOTE: This kit is primarily designed to only be driven in 2WD at speed on public roads and that 4WD is only to be used off-road or in adverse slow-speed conditions due to driveline vibrations at high speeds. Double Cardan driveshaft may be required to help eliminate some of the high speed 4WD front driveline vibration when kits are 5-8" high.
