King shocks are huge with the Jeep folks. I don't think they market as much to the Raptor folks. If it is like many other things these products are very similar. Whatever you spend your money on will most likely be the BEST in your mind. Hence some of the silly comments on this thread. The argument that this race group uses (X) suspension system so it is best is exactly why (X) sponsors that race group and is a foolish supposition as it is purely a marketing ploy used by many many companies. I expect if you purchased Fox or King you would be most pleased either way.
