2020 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 Capable 2020 One-Ton Long Bed
The 2020 Ford F-350 Super Duty continued the proven one-ton heavy-duty platform with meaningful refinements that reinforced the F-350's position as the benchmark one-ton work truck on the road. Expanded powertrain options, enhanced towing and payload technology, and continued development of the available 6.7L Power Stroke diesel gave the 2020 F-350 more capability on an already proven foundation.
What remained unchanged was the proven 8' Long Bed architecture introduced with the current generation Super Duty design.
The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2020 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.
Whether your truck is used for construction hauling, farm and ranch operations, commercial material transport, equipment hauling, or everyday one-ton heavy-duty work, Thunder Armor delivers dependable truck bed protection designed to match the capability of the 2020 F-350 Super Duty.
