Professional Grade Hauling for Your Capped Truck
Elevate your truck’s cargo capacity to a professional level with the Kargo Master 4C6AMR Pro III HD Aluminum Truck Cap Rack. Engineered specifically for work trucks equipped with commercial caps, this rack system provides an incredibly strong, stable, and lightweight platform for hauling oversized equipment without compromising your vehicle’s covered storage. Built by Kargo Master, a leader in commercial-grade utility racks, the Pro III is the ultimate solution for contractors, tradespeople, and adventurers who demand uncompromising performance, durability, and corrosion resistance for their most challenging jobs and expeditions.
Unmatched Strength and All-Weather Durability
The foundation of the Pro III rack is its construction from T-6 aircraft-grade aluminum, which offers an exceptional strength-to-weight ratio. This means you can confidently transport up to 1,000 lbs of distributed weight—from stacks of lumber and long pipes to multiple extension ladders—without adding excessive weight to your vehicle. The aluminum is finished with a durable anodized coating, rendering it 100% rustproof and ready to withstand years of exposure to rain, snow, and road salt. The aerodynamic crossbars are not only strong but are also designed to minimize wind noise and drag, helping to maintain fuel efficiency and a quiet ride at highway speeds. Fully welded gussets and high-grade stainless steel hardware ensure every connection point is robust and secure for the long haul.
Versatile and User-Friendly Design
Designed for maximum utility, the Kargo Master 4C6AMR is more than just a set of bars; it’s a complete cargo management system. The crossbars feature integrated T-slots, allowing for the quick and secure mounting of a wide range of accessories, including ladder stops, tie-down loops, and conduit carriers. This versatility makes it the perfect Truck Rack Kit for electricians, plumbers, carpenters, and any professional who needs to adapt their setup for different jobs. The rack mounts directly to the reinforced structure of most commercial truck caps on 6.5-foot beds, creating a solid, integrated system that maximizes your truck’s hauling potential while keeping your bed contents secure and protected from the elements.
