2019 RAM 3500 6'5" Hard Folding Truck Bed Cover

Premium Low Profile Aluminum Truck Bed Cover

Premium Aluminum Truck Bed Cover Built for the Launch Year of the Fifth Generation RAM 3500


The 2019 RAM 3500 introduced the fifth-generation heavy-duty platform — a landmark redesign that brought a new fully boxed frame with increased high-strength steel content, a completely redesigned interior with available 12-inch Uconnect touchscreen, a revised suspension system, updated bed architecture, and continued availability of the proven 6.7L Cummins High Output diesel. For the RAM 3500 specifically, the 2019 redesign delivered a new generation of one-ton engineering — a platform built for the heaviest commercial, agricultural, and gooseneck towing demands through 2026 and beyond.

For operators who chose the 6'5" Standard Bed in 2019, that decision combined the all-new fifth-generation one-ton platform with maximum standard bed length — built for operators who need maximum payload capacity and full bed length in every operation.

The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2019 RAM 3500 6'5" Standard Bed on the fifth-generation platform. 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 heavy-duty truck use.

Whether your truck is used for heavy construction hauling, farm and ranch operations, commercial fleet work, gooseneck towing, or maximum payload one-ton applications, Thunder Armor delivers dependable truck bed protection designed to match the capability of the 2019 RAM 3500.
