Overview
The DualLiner DULFOS1765-N is a five-piece truck bed liner system for the 2017–2020 and 2022 Ford F-250 and F-350 Super Duty. It uses hard, custom-fitted panels for the bulkhead, sides and tailgate, set against a 3/8″ thick ZeroSkid Rubber Floor, which gives the walls dent protection and a mat meant to hold cargo in place.
Super Duty owners often carry equipment, building materials or trailer gear in the bed, and this liner keeps that surface protected. The panels and floor come as one system, covering the bed from the cab to the tailgate. The rubber floor has many soft cleats underneath that let water and air move below the mat, which helps protect the finish and paint.
Key features
- Five-piece system with custom-fit, hard dent-protection panels for the bulkhead, sides and tailgate.
- 3/8″ thick ZeroSkid Rubber Floor that interlocks with the sidewall panels.
- Rubber cleats on the floor underside, which allow drainage and airflow.
- Floor intended to keep cargo from sliding during use.
- Protects the bed walls and surface from dents and scratches.
- Includes a lifetime warranty.
Working with heavy loads
Super Duty trucks often carry heavier cargo than lighter pickups, including building materials, pallets and trailer gear. Those loads test a bedliner in different ways: panels take impact from dropped items, and the floor has to keep material from sliding into the bed corners. Good loading habits protect both the liner and the paint underneath it.
Place heavy items toward the cab where possible, and slide them rather than dropping them. Use the tie-down points for anything that could move in a stop. After heavy use, check the panels for bowing or edges pulled away from the walls, since loose panels allow grit to reach the bed surface.
- Slide heavy items in rather than dropping them
- Anchor loose cargo at tie-down points
- Check panels for bowing after heavy loads
- Keep the floor clear of grit and fasteners

Installation notes
DualLiner describes installation as a simple 30-minute job. Because the panels are custom-fitted to the bed and the floor interlocks with the sidewalls, the pieces are designed to be fitted together as one system rather than used separately.
What’s included
The five-piece system includes the bulkhead, sidewall and tailgate panels along with the ZeroSkid Rubber Floor. Verify all parts and any mounting hardware against the package before beginning the fitting.
