The Crossfire conversion kit consists of the springs and everything needed to mount them. The kit uses 2.5" ID springs in the front and 2.25" ID springs in the rear. Nothing more is included in the BASIC kit that I know of. The shocks cost extra and vary according to if it's a race shock, street shock etc. Koni makes a large variety. The links cost x amount extra for each link. They're are 4 links per side in the rear or 8 in all. I got them all, because race car. The adjustable sway bar links are also extra. 2 in all. I know what I paid but not if what I paid is the final price or not.
