B&W WDHK4501 Continuum Weight Distribution Hitch Kit Underslung Coupler 16K GTW

The B&W WDHK4501 Continuum Weight Distribution Hitch Kit is an innovative towing solution designed for underslung trailer couplers with 2-inch receivers. This complete kit features advanced hydraulic technology and composite spring bars that revolutionize the weight distribution experience for heavy-duty towing applications.

Engineered with Hendrickson LITEFLEX technology, this system handles gross trailer weights up to 16,000 lbs with tongue weights ranging from 600 to 1,600 lbs.
