CURT 2024044577 Helux Coil-Spring Gooseneck Pin Box 20,000 lb. Capacity 3,900 lb. Max Pin Weight

The CURT Helux Coil-Spring Gooseneck Pin Box (Part #2024044577) is a heavy-duty fifth-wheel towing solution engineered to deliver a smoother, more comfortable ride while maximizing truck bed usability. By converting a traditional 5th wheel setup to a gooseneck connection, this pin box frees up the full bed of your truck without sacrificing towing performance or stability.

At the core of the system is CURT's proprietary coil spring and shock absorber technology, designed to absorb road vibrations, reduce chucking, and minimize jarring forces transferred to your RV. Compared to similar pin box designs, the Helux reduces force on the RV frame and body by up to 30%, helping protect your trailer's structural integrity over time.
