Demco Hijacker frame brackets are engineered to fit all major makes and models of trucks. Deco offers three different mounting styles for our Hijacker 5th wheel hitches; Premier Series, SL Series and UMS Series. Many of which have "no drill" options for a simpler, time saving installation. The Premier Series are our industry standard bed rail and use four bolts to mount the rails in the truck bed and connect to the brackets underneath.
