Stay away from the frame mounted rocker panel guards. If you come down hard on a rock they'll bend right up into your body panels. Get the ones that mount to the body. Check out the Poison Spyder Ricochet Rockers (with step) or the ones without a step. They may be a little expensive but they're STRONG. IMO Quadratec is one of the more expensive suppliers. Use someones catalog or the internet, find what you want, then use the internet to find your best price.
