    This kit had everything, shims for precise adjusting to prevent gear whine, all the oil and bolts needed, along with the speed caliper all that isnt included is the labor, these gears have insane acceleration making second and third run through almost as fast as stock first gear. -3.73 gears and the supercharger with exhaust gave me a 12.88 quarter mile :)
