2011 RAM 3500 6'5" Hard Folding Truck Bed Cover
Premium Low Profile Aluminum Truck Bed Cover
Premium Aluminum Truck Bed Cover Built for the Second Year of the Fourth Generation RAM 3500
The 2011 RAM 3500 continued the fourth-generation heavy-duty platform with second-year refinements — updated technology packages, improved powertrain calibration of the 6.7L Cummins diesel, and expanded trim availability. The 6'5" Standard Bed carried forward the same proven fourth-generation rail geometry from the 2010 launch, now backed by one full year of real world validation across demanding commercial, agricultural, and one-ton heavy-duty applications.
The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2011 RAM 3500 6'5" Standard Bed on the fourth-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.
