For any X rock sliders are a must to get down to the obstacle without damage. We all touched our sliders even roger with the 3+2 lift. Not to mention the fact that we were all running 32 inch tires. A stock suspension would have a tougher time but I don't think it would be impossible. Agressive tires are a definite must have though. During this obstacle I learned what those aggressive lugs on the sides of our tires are for.
