The CURT Helux Coil-Spring Gooseneck Pin Box (Part #2024044574) is a heavy-duty towing solution engineered to deliver a smoother, more controlled ride when towing fifth-wheel trailers via a gooseneck connection. Rated for a 20,000 lb. gross trailer weight capacity and a maximum pin weight of 2,700 lbs. (minimum 1,550 lbs.), this pin box is built for RV owners who demand performance, comfort, and durability on every haul.
At the core of the Helux system is CURT's proprietary coil and shock technology, which reduces force on the RV frame and body by up to 30% compared to similar gooseneck pin boxes. An automotive-grade coil spring absorbs road shock — crossing railroad tracks, rough pavement, and highway miles — delivering a quieter, more comfortable experience for drivers, passengers, and pets alike.
Unlike airbag-style pin boxes, the Helux is virtually maintenance-free: no air pressure checks, no compressors, no adjustments, and no break-in period required. The auto-latching coupler connects quickly and securely to any standard 2-5/16" gooseneck ball, streamlining hookups and getting you on the road faster. The gooseneck connection also frees up full use of your truck bed compared to traditional fifth-wheel setups.
