skid plate
your correct it is PVC step one: increase your pre load to setting two at least (you'll thank me), step two get a 2" or 3" lift kit, step three get bigger tires and rims (15R x 30") at least, step four get offset a arms with some lift, or simply pay $1500 for the full aluminum skid plate and crank your pre load to three.
Second run out I put a rock into my pvc floor from using the factory pre load setting of one there was to much travel and it bottomed out on the rock.
