Ford F-350 Tonneau Covers

Ford F-350 tonneau cover lineup

The Ford F-350 Super Duty is the heavy-hauler in the F-Series and tonneau covers for it focus on hard-panel security, high load ratings, and long-bed coverage. Truck Bed Barn stocks covers across every major style for the 6.75' and 8' Super Duty beds.

Most-shopped covers for the F-350 include the BAKFlip MX4 (400 lb), the Extang Solid Fold ALX (600 lb rating), the RetraxPRO XR with T-Slot rails, and the Extang Solid Fold Toolbox 2.0 for crossover toolboxes.

F-350 Super Duty shares bed and rail geometry with the F-250, so most covers fit both interchangeably. Generation breaks at 1999–2007, 2008–2016, and 2017–2026. Covers are sized per generation and bed length — verify before ordering.

Run your F-350 through the fitment tool or message us before you order. Fitment is verified before every cover ships.

Ford F-350 tonneau cover FAQ

What is the best tonneau cover for an F-350?
The Extang Solid Fold ALX is the top pick for highest load rating (600 lb evenly distributed). The BAKFlip MX4 is the best-selling hard fold at 400 lb capacity. For retractable bed access, the RetraxPRO XR or Roll-N-Lock A-Series.
Do F-250 and F-350 tonneau covers fit interchangeably?
Yes, in most cases. F-250 and F-350 Super Duty share bed-rail geometry within the same generation, so a cover sized for the 6.75' F-250 bed fits the 6.75' F-350 bed of the same generation. The 8' long bed on dually F-350 configurations also matches the F-250 8' long bed.
Does an F-350 dually need a different cover?
No. The dually rear axle does not affect the bed dimensions or rail geometry — dually F-350 trucks use the same 8' long bed as single-rear-wheel F-350s in the same generation. Covers are sized by bed length, not axle configuration.
What about F-350 toolbox-fit covers?
The Extang Solid Fold Toolbox 2.0 (hard) and Trifecta Toolbox 2.0 (soft) are sized to fit behind most 18–20 inch crossover toolboxes via a patented L-Channel that seals the gap.
How do you install an F-350 tonneau cover?
No-drill clamp-on mounting. Most installs finish in under an hour with basic hand tools. Electric retractables also require wiring to the battery.
Will a tonneau cover fit my exact F-350?
Covers are sized per year, generation, and bed length. The wrong size will not seal. Use the fitment tool or message us before you order.
