Curt Helux Coil-Spring Gooseneck Pin Box, 3,900 lbs. Pin Weight, 20,000 lbs. Capacity - 2024044577

Take your RV towing experience to the next level with the CURT Helux Coil-Spring Gooseneck Pin Box — designed for superior ride quality, increased cargo space, and uncompromising durability. This innovative pin box replaces your traditional 5th wheel setup with a gooseneck connection, giving you full access to your truck bed for tools, gear, or whatever else the road demands. At the core of the design is CURT’s proprietary coil and shock technology, engineered to dramatically reduce chucking and jarring. The result? A smoother, more stable ride that helps protect your trailer, your cargo, and your passengers. Compared to similar pin boxes, the Helux gooseneck pin box cuts down on force to the RV frame and body by up to 30%, helping to preserve the structural integrity of your trailer over time. Whether you’re hauling across the state or across the country, comfort matters. That’s why we use an automotive-grade coil spring to deliver a more forgiving ride that's especially noticeable for passengers and pets. And with a virtually maintenance-free design, there’s no air pressure to check, no components to adjust. Just install it and go. No break-in period required. The CURT Helux Coil-Spring Gooseneck Pin Box is built to handle heavy-duty demands, with a 20,000-lb. gross towing weight rating and pin weight capacity ranging from 2,200 to 3,900 lbs. The auto-latching coupler connects quickly and securely to any standard 2-5/16” gooseneck ball for a streamlined hookup process so you can get on the road faster. Finished in a durable black powder coat and tested to meet SAE J2638 safety standards, this pin box is built to last. It’s compatible with the Rhino Box bolt pattern and approved for use on Lippert RV frames, so you can tow with confidence knowing it won’t void your manufacturer warranty.
