Actually most of the major shock makers' house brand twin tube hydro and nitro shocks are the same things with different part number stamped on the side and different paint colors. There was a fellow on Off-Road.com's Jeep forum a few years back that let that one out of the bag. Ever notice that Superlift, Rancho, ProComp, Skyjacker, etc etc all have 10 stage twin tube shocks for just about the same price (Rancho excluded)?
Oh, if you want a Rancho 5000 just go buy a Monroe Truck shock. Even better yet get the NAPA Reflex shock which is cheaper and nitro charged not hydraulic.
ANYWAYS...
Just to clarify while Mud Kings are made by a company that is owned by the same French company that owns BFG they are not the same thing. Completely seperate tread designs, carcasses, sidewalls, etc. Frankly though I'd buy a set of Mud Kings long before a set of BFG's. Don't rock crawl and don't feel like paying extra for the famous 3 letters. All those Baja championships seem to make the cost go up.

I've had great service from Multimile, General, Cooper's offbrands, Cavalier (Mud Kings), etc without having to shell out tons of dough for big name tires. Heck, even my Interco TrXus MT's where cheaper than the equivalent BFG or Goodyears.
