The Thunderstone Manufacturing Standard

Since 1884, under the Timpte name

Rooted in the same manufacturing standard that has supported commercial transportation and industrial markets since 1884, Thunder Armor was created by Thunderstone Manufacturing, a division of Timpte, Inc., to bring that same commitment to quality, craftsmanship, and long-term performance into the truck accessory market.

Built for Real Life

Rugged utility, clean design

At Thunderstone Manufacturing, we believe truck accessories should do more than simply look good. They should work hard, last long, and stand up to real-world use. Every Thunder Armor truck bed cover is developed with a focus on durability, fit, functionality, and the everyday needs of truck owners across work, recreation, towing, and outdoor lifestyles. Every latch, seal, and panel is built to hold up to the jobsite, the track, the farm, and the weekend outdoors.

Thunder Armor is more than a product line. It represents a growing brand built around protection, performance, and ownership pride. Whether on the jobsite, at the track, on the farm, or heading outdoors for the weekend, Thunder Armor products are designed to help customers protect what matters and get more out of their trucks every day.

Nebraska-Made, American-Made

As a Nebraska-based manufacturer, we take pride in American manufacturing and the people behind our products. Our aluminum is extruded in the United States, and our team is committed to delivering products that reflect strong Midwestern values, practical innovation, and a dedication to doing things the right way. As Thunderstone Manufacturing continues to expand the Thunder Armor lineup, our focus remains the same: build high-quality products, support our customers, and create solutions that are Built for Real Life.
