All Crossover Truck Tool Box Options

UWS truck tool boxes are assembled with pride in the USA and available in a variety of sizes and configurations to match the demands of your work and your Ram 2500 or 3500. Each crossover-style box is built tough, featuring our signature RigidCore™ lid for added strength, durable aluminum construction, and MicroSeal™ technology to help block out dust, debris, and bad weather. Most models built for Ram 2500 & 3500 trucks come equipped with several of the features highlighted below.

What Sets Our Ram 2500 & 3500 Tool Boxes Apart From the Rest

1. RigidCore Lid

RigidCore™ is a patented lid design found only on UWS tool boxes. Instead of a hollow structure, each lid is packed with a specialized expanding foam that hardens between dual aluminum panels. This method creates a solid, ultra-rigid build that dramatically boosts strength compared to traditional lids.

2. Extra-thick Aluminum Construction

UWS tool boxes and storage chests are constructed with thicker aluminum than what’s commonly used in the industry. While many competitors settle for material in the 0.045" to 0.050" range, we use 0.058" diamond-plate aluminum that's built to handle demanding conditions with superior toughness and long-lasting durability.
