This secondary shock hoop will give you a huge upgrade in performance and handling from your long travel ifs kit. Most 4wd models crave this kit to help deal with the extra weight of the front differential. When you install dual 2.5 shocks it increases tune ability and increases the dampening charcateristics. The hoops run a secondary 8" travel 2.5 or 2.0 non coil or bypass shock. These hoops are built from 4130 cro moly and include all the hardware to install the hoop. The bolt patterns on the top of the shock mount vary from vehicle to vehicle so you must specify vehicle type at the time of order. There is welding and grinding required to install these hoop on the vehicle.
