Frequently bought together
Why it works
Two styles, more tire clearance
Choose a straight cut or a 45-degree angle; both S&B Mud Flap Deletes add tire clearance for larger tires, reduce contact with the lower inner fender and clean up the look. Watch the cut and no-cut install videos.
Over 50% shorter than stock
The factory mud flaps are about 6 inches long. S&B's are 2 3/4 inches, giving tires more room in turns, during suspension travel and off-road.
6 fender caps included
The kit's 6 pieces replace both flaps around the rear tire and the flap behind the front tire.
Installation
Bolt-on with hand tools. Grab the manufacturer’s step-by-step instructions, or watch the install first. Stuck partway? Call real humans at (920) 249-7744.
