It should have liners or debris guards out of flexible rubber skirt material on both sides. From the factory they extend from the edge of the lower metal inner fender to the top of the frame and overlap it by a bit in places even with a body lift.
If you are missing yours, I have several serviceable sets of which you are welcome to a pair of for the price of shipping. I also have the plastic push in retainers often referred to as christmas tree clips, fir tree fasteners and such if needed.
