Tow With Confidence Right From The Driver Side

If you're looking for a smarter, smoother way to tow, the B&W WDHK4501 Weight Distribution Hitch is built to deliver exactly that. This system doesn't just level your load, it actively improves handling with continuous sway control that kicks in the moment you're on the road. The composite spring bars are incredibly strong yet lightweight, making setup quicker and easier without sacrificing performance. And because every adjustment happens on the driver’s side, there’s no crawling around the trailer to get things right. Loading the bars is as simple as pumping the built-in handle until the front axle regains traction, giving you confident control every time you hit the highway. The pressure gauge takes the guesswork out of setup, so whether you're towing the family camper or a heavy utility trailer, your settings stay consistent. It's a well-thought-out system that makes towing safer and setup less of a chore, so you can spend less time fiddling and more time rolling.

Engineered Strength Meets Smarter Weight Control

Behind the scenes, this hitch brings some serious engineering to the table. It features tapered composite spring bars built with Hendrickson’s LITEFLEX technology, giving you 5 times the flexibility of steel without losing strength or durability. Rated for tongue weights from 600 to 1600 pounds, it’s designed to handle a wide range of trailer sizes while reducing strain on your vehicle. The preset head angle is tuned to fit most towing setups right out of the box, cutting down on installation time. A single pivot point keeps the design simple and eliminates the clunky noises and wear that come with traditional multi-point hitches. The shank fits any standard 2 inch receiver, and it’s compatible with underslung couplers, making it versatile for different trailer styles. The twist-release needle valve lets you unload the bars smoothly, wrapping up your tow session without stress. Whether you're heading out for work or play, this hitch is built to perform in real-world conditions.
