Overview
The DualLiner DULFOS9980 is a five-piece truck bed liner system for the 1999 Ford F-250 and the 1999–2007 Ford F-250 and F-350 Super Duty. Custom-fitted, hard panels cover the bulkhead, sides and tailgate, and a 3/8″ thick ZeroSkid Rubber Floor completes the set, giving the bed dent protection on the walls and a mat that is meant to keep cargo from shifting.
Owners of older Ford heavy-duty pickups who use the bed for work loads, tools or gear are the people this liner is built for. The panels and floor interlock, so the liner is used as one system. The rubber floor has soft cleats on its underside that allow drainage and airflow, which helps protect the finish and paint of the bed.
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.
- Soft rubber cleats on the floor underside for drainage and airflow.
- Floor intended to keep cargo from moving during use.
- Protects the bed walls from dents and scratches.
- Lifetime warranty on the system.
Older trucks and bed wear
Bed liners on older trucks often go over a bed that has seen years of work. Before fitting any liner, look at the bed floor and the lower wall seams for rust, dents or loose paint. A liner that traps moisture against weak metal can speed corrosion, so the bed surface should be sound and dry before installation.
Older Ford pickups also tend to have worn tailgate hinges and bed bolts, which can shift a panel over time. Check fasteners after the first few trips and again at routine service. Keep the rubber floor clear of grit so it does not rub on painted surfaces, and clean the bed after wet or muddy work.
- Treat rust before fitting the panels
- Inspect bed seams and wall joints for loose metal
- Check fasteners after the first few trips
- Clean the bed after wet or muddy hauling
