⚠️ Vehicle Fitment Required

Demco frame brackets and base rails are truck-specific — the same part number fits only the year, make, model, and bed length Demco's application guide assigns it to. Before ordering, confirm the part number against Demco's fifth wheel application guide for your truck, or send us your truck's year, make, model, bed length, and hitch series (Premier, SL, UMS, Hijacker, Autoslide) and we'll verify. Drilling may be required. Ships freight on heavier kits.
