Fits: 2001 Thru 2014 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM/LML Duramax Diesel 6.6FT Bed

The most advanced tonneau cover ever made. The BakFlip F1 Fiberglass reinforced polymer top provides unparalleled impact resistance while the aluminum underside ensures absolute structural security.
The BakFlip F1 was designed for people that are particularly hard on their tonneau covers or who live in climates that are subject to a lot of hail, ice and snow. Made from materials that are virtually indestructible, the BakFlip F1 is a tonneau cover that is much stronger than the body of your pickup truck. It will never dent through normal daily use, even when you drop something heavy on it or get caught in a severe hail storm. The BakFlip F1 also stays relatively cool to the touch. Unlike its sisters, the BakFlip G2 and BakFlip HD, the fiberglass top surface will not heat up like aluminum. We have kept the substrate of the BakFlip F1 tonneau cover aluminum because aluminum will never expand and contract, so as far as structural stability, The BakFlip F1 truck bed cover performs just like we want. PERFECTLY! The fiberglass reinforced polymer top also has a transparent coat which protects it from fading and is completely UV resistant. The BakFlip F1 will remain looking as good on the truck in 5 years as it does from the day you put it on your truck. BakFlip F1 Tonneau Cover is Lighter and Stronger than Aluminum.
