On my truck a little was cut out of the frame to keep the bag from rubbin against it. You might have to cut out the wheel tubs, depending on your wheel size. When I have my 205/40/17s on, when the truck is totally laid out its like half an inch off the ground. Then again I drug off the front xmember.....which inturn enabled me to drag a hole in my oil pan. Dont even get me started on all the stuff I broke from draggin and tryin to hop
