2018 Ford F-350 8' Long Bed Hard Folding Tonneau Cover

Premium Low Profile Aluminum Truck Bed Cover

Premium Aluminum Truck Bed Cover Built for the One-Ton Long Bed Work Truck

The 2018 Ford F-350 Super Duty 8' Long Bed owner made a deliberate operational decision. One-ton capability combined with maximum bed length means the ability to carry full lengths of lumber, pipe, conduit, or steel without a load flag, and the payload capacity to handle commercial and agricultural loads that would exceed a lighter truck's limits.

The 2018 F-350 8' Long Bed is a purpose-built working tool, and every accessory on it should be chosen with that purpose in mind.

The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2018 Ford F-350 8' Long Bed. Designed and manufactured in the USA by Thunderstone Manufacturing, this premium hard aluminum truck bed cover delivers enhanced cargo security, all weather protection, rugged durability, and a sleek low profile appearance built for real world truck use.

Built from premium grade aluminum and engineered for demanding one-ton commercial, agricultural, and long haul applications, Thunder Armor helps protect the tools, equipment, materials, and cargo that serious long bed operators rely on every day.
