The CURT A20 5th wheel hitch offers smoother, quieter towing for your home-away-from-home, combining the patented technology of our A-series, an easier mounting system and the power of a 20K 5th wheel hitch. Like our A16 hitch, this 20K 5th wheel hitch uses a patented cast yoke to allow for unimpeded head movement, while providing exceptional stability for the trailer. The yoke has a set of poly-torsion inserts to suppress shock loads and reduce excessive noise, and the head features high-strength, interlocking jaws to give the trailer stability and the freedom to pivot and swivel as needed. To protect the A20 5th wheel hitch against rust, wear and whatever other threats might impede your cross-country tour, it comes with a carbide black powder coat finish and a limited lifetime warranty. We also test the A20 for safety in accordance with SAE J2638 to ensure reliability for the road ahead. NOTE: This A20 head unit is designed to be a replacement head only. It requires 5th wheel legs or a 5th wheel roller to be installed. These components are not included in this package.
