KA4910 / KA4910 - Application Notes When it comes to sprucing up a vehicle design, STILLEN wrote the book, and their newest Bumper Cover/Spoiler for the Ford F-150 is just what the popular truck needs. Designed to "pop" directly over the factory bumper, the Cover is easy to install and perfect for redesigning leased vehicles. It also offers customers the ability to install accessory driving lights, which further add to the design and functionality of the F-150. Constructed of resilient urethane, the Cover is paint-able and comes with a Limited-Lifetime Warranty against cracking or breaking under normal use. After 17 years of in-house urethane production, the F-150 Bumper Cover/Spoiler represents another benchmark in quality, featuring the fit and finish normally reserved for Original Equipment products.
