2010 RAM 2500 8' Hard Folding Truck Bed Cover

Premium Low Profile Aluminum Truck Bed Cover

The Longest Working Bed Gets the Strongest Cover — Built for the Launch Year of the Fourth Generation RAM 2500

The 2010 RAM 2500 introduced the fourth-generation heavy-duty platform — a landmark redesign that brought a new fully boxed frame, a revised suspension system with available coil-spring rear setup, the proven 6.7L Cummins High Output diesel, and a completely updated interior. The operator who chose the 8' Long Bed on their 2010 RAM 2500 made a clear statement: maximum hauling length, maximum payload capacity, and a truck built for the most demanding applications the half-ton segment cannot reach.

The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2010 RAM 2500 8' Long 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.

Important: Thunder Armor for the RAM 2500 8' Long Bed does not work with drop-in bed liners. Remove drop-in liners before installation.
