B&W Continuum™ WDHK4505 Weight Distribution Hitch | Underslung | Extended Shank

Upgrade your towing performance with the B&W Continuum™ Weight Distribution Hitch (WDHK4505) — a premium extended-shank system designed for trailers equipped with underslung couplers. Available now at newrangeonline.com, this advanced hitch package includes the durable WDHH4504 Head Assembly, the WDHL4511 Load Bar Unit, and a factory-installed 2-5/16” hitch ball, all mounted on an extended 2-inch shank for additional clearance and improved fitment versatility.

The Continuum™ system is engineered to replace traditional spring-bar hitches with a smoother, quieter, and more intuitive solution. Its load bar technology provides automatic, progressive weight distribution, significantly improving handling, sway control, braking stability, and overall towing comfort. No more clunky bars or noisy tensioning—just seamless performance mile after mile.

Optimized for underslung trailer couplers, the WDHK4505 ensures proper geometry and maximum efficiency, especially on trailers with low-mounted couplers. The extended shank gives your tow setup the extra room needed for tailgates, accessories, and unique vehicle configurations.
