CURT 16140 A20 5th Wheel Hitch 20000 lb GTW

The CURT A20 5th wheel hitch delivers smooth, quiet fifth-wheel towing with 20,000 lb gross trailer weight (GTW) capacity and 5,000 lb vertical load rating. Built around CURT's patented A-Series torsion technology, the A20 is engineered for both performance and ease of use — from first installation to everyday coupling.

At the heart of the hitch is a patented cast steel yoke paired with poly-torsion inserts that absorb road shock and suppress towing noise. The fully articulating torsion head allows the trailer to pivot and swivel freely while maintaining a stable, secure connection. High-strength, interlocking cast jaws fully wrap the kingpin to minimize chucking noise and maximize towing security.
