To be able to do that though and weather all the curbs, road junk and little woodland creatures that gets thrown at it without coming apart is tough. Good Hood's Air Dams delivers on this purpose. What's more, you can quickly and easily install this to your truck via the predrilled mounting holes in factory bumpers. Good Hood Air Dams uses factory supplied fog lights and tow hooks. It comes complete with instructions and mounting kit with ABS construction. Shipping is via UPS.
