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 SL-Series uses a manual slider rail that runs front to back in the truck bed and attached the bed rails with six bolts to connect to the brackets underneath. The 8553014 Hijacker SL-Series Frame Mounting Bracket Kit from Demco is compatible with 2014 to 2018 Chevrolet Silverado and GMC Sierra 1500 Trucks (5.5', 6.5' and 8' beds) (Regular, double and crew cabs). Refer to Demco's recommendations to ensure a model specific fit before purchasing.
