CURT Helux Coil-Spring Gooseneck Pin Box, 2,350 lbs. Pin Weight, 20,000 lbs. Capacity

The CURT Coil-Spring Gooseneck Pin Box with 2,350-lb. pin weight is engineered for RV owners who demand more from their towing setup – more ride comfort, more truck bed space, and more long-term durability. By utilizing a gooseneck connection, this pin box gives you full use of your truck bed without sacrificing performance or stability. At the heart of the system is CURT's proprietary coil and shock technology, designed to dramatically reduce the bumps, jolts, and vibrations that come with towing. Compared to traditional pin boxes, the Helux Pin Box cuts down on force to your RV frame and body by up to 30% compared to other gooseneck pin boxes. With the Helux, you'll feel the difference right away. The automotive-grade coil spring absorbs road shock to deliver a smoother, quieter ride for both pets and passengers.

Unlike airbag-style pin boxes, the Helux is virtually maintenance-free. No compressors. No adjustments. No break-in period. Just install it and tow. Built to handle serious loads, this pin box offers a 20,000-lb. gross trailer weight rating with a max pin weight of 2,350 lbs. The auto-latching coupler connects quickly to any standard 2-5/16" gooseneck ball, making hookups fast, easy, and secure. It's also built to last. The CURT coil-spring gooseneck pin box features high-strength steel construction, a durable black powder coat finish, and has been rigorously tested to SAE J2638 standards for safety and reliability. Plus, it's compatible with Rhino Box bolt patterns and approved for use on Lippert RV frames, so it won't void your manufacturer warranty.

SMOOTHER, MORE COMFORTABLE RIDE – The CURT Helux Coil-Spring Gooseneck Pin Box utilizes innovative coil and shock technology to minimize jarring and chucking while towing. This means fewer harsh jolts on rough roads, reducing fatigue for drivers and providing a steadier, more enjoyable ride for passengers and pets.

REDUCED FRAME STRESS – Engineered to protect your RV, the Helux Coil-Spring Gooseneck Pin Box reduces force on the frame and body by 30% compared to similar designs. This helps extend the lifespan of your RV while keeping your trailer and gear more secure, preventing unnecessary wear and tear on your investment.
