Demco 5th wheel frame brackets are engineered to fit all major makes and models of trucks. Demco offers three different mounting styles for our 5th wheel hitches; Premier-Series, SL-Series, and UMS-Series. Many of them have “no drill” options for a simpler, time-saving installation. The Premier-Series is Demco's industry standard bed rail and use four bolts to mount the rails in the truck bed and connect to the brackets underneath. The 8552003 Hijacker Premier-Series Frame Mounting Bracket Kit from Demco is compatible with 2004 to 2014 Ford F150 Trucks (5.5', 6.5' and 8' boxes). Refer to Demco's recommendations to ensure a model specific fit before purchasing.
