The CURT Helux Coil-Spring Gooseneck Pin Box (Part #2024044576) is a heavy-duty fifth-wheel-to-gooseneck pin box engineered for RV owners who demand superior ride comfort, maximum truck bed access, and long-term towing durability. With a 20,000 lb. gross trailer weight rating and a maximum pin weight of 3,200 lbs. (minimum 1,800 lbs.), this pin box is built to handle the most demanding towing configurations.
At the core of the Helux system is CURT's proprietary coil and shock technology, designed to dramatically reduce the chucking, jarring, and vibrations common with traditional fixed pin boxes. Compared to similar gooseneck pin boxes, the Helux reduces force on the RV frame and body by up to 30%, helping preserve the structural integrity of your trailer over time. An automotive-grade coil spring delivers a smoother, quieter ride for both passengers and pets on every journey.
Unlike airbag-style pin boxes, the Helux requires no compressors, no adjustments, and no break-in period — simply install and tow. Its virtually maintenance-free design means fewer ongoing costs and more time on the road. The auto-latching coupler connects quickly and securely to any standard 2-5/16" gooseneck ball for fast, reliable hookups.
