Upgrade your truck's towing and hauling performance with the FR1504D Rear Load Support Kit, engineered to deliver a massive 8,600 lb load assistance capacity for demanding work conditions, heavy cargo, trailers, campers, and equipment hauling. This high-strength rear load solution provides exceptional stability by reducing rear sag, sway, and body roll, helping your truck maintain a level, controlled stance even under extreme weight. The advanced progressive rubber spring design adapts to pressure automatically—light loads ride soft and comfortable, while heavier loads activate firmer support for maximum stability and improved control. This reduces excessive bouncing, rear-end squat, and unwanted side-to-side movement, allowing safer handling, improved braking response, and more predictable steering while towing or hauling. Built for zero maintenance, the FR1504D requires no air lines, compressors, or routine adjustments. The durable rubber construction resists cracking, heat, road salt, and weather exposure, ensuring long-term reliability. Its rugged mounting components provide consistent performance year after year, no matter how challenging the workload. Installation is fast, simple, and DIY-friendly, using standard tools and factory mounting points—no drilling or complicated setup required. The kit integrates seamlessly with your truck while enhancing performance without affecting unloaded ride comfort. Whether you use your truck for construction, landscaping, towing recreational trailers, hauling equipment, or daily heavy-duty work, the FR1504D Rear Load Support Kit gives you improved stability, reduced sag, smoother towing, safer handling, and a more confident, level ride under every load.
