2009 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 Final Year of the Third Generation RAM 2500


The 2009 RAM 2500 was the final model year of the third-generation heavy-duty platform — the last expression of a RAM heavy-duty architecture that had powered commercial and agricultural operations across North America for years. Operators who chose the 8' Long Bed on their 2009 RAM 2500 chose maximum hauling length on a proven three-quarter-ton platform, and maintaining that truck with quality accessories is an investment in long term performance.

The Thunder Armor Hard Folding Tonneau Cover is precision engineered specifically for the 2009 RAM 2500 8' Long Bed on the third-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 long material transport, heavy hauling, farm and ranch operations, commercial work, or everyday maximum payload applications, Thunder Armor delivers dependable truck bed protection designed to match the capability of the 2009 RAM 2500 8' Long Bed.

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