JIGGA - It's the Rancho 4". They call it a 4" but it was actually over 5" not counting the tires, which added another 1".....Which brings me to DRTYFN's comment: Your right, it is somewhat open (it does seal against the hood...in spots

) but factory water clearance height is 20" with the lift I have over 26". If the rig ever sees that much water I will have other bigger problems before water problems. Although I am thinking of ways to close in the filter better in case of major splashing. I do serious mud drag racing, so I really understand the water thing.
