Get Better Control Without The Guesswork

If towing has ever felt like a chore, the B&W WDHK4503 Weight Distribution Hitch changes the game. Designed with everyday users in mind, this system makes setup simple and driving far more stable. It’s all handled from the driver’s side, so you’re not crawling under the trailer or walking laps around your setup. You’ll load the bars by pumping the built-in handle, and once the front axle starts to level out, you're good to go. A pressure gauge gives you confidence every time, showing exactly how much force is being applied so there’s no need to guess. When you're ready to unhook, just twist the needle valve and release the tension with ease. Whether you're towing your travel trailer through the mountains or hauling a cargo trailer on the interstate, the built-in sway control kicks in right away, helping you stay in control even when the wind or road conditions don't cooperate.

Built For Underslung Trailers That Need Real Strength

This hitch is built specifically for trailers with underslung couplers and fits standard 2.5 inch receivers, making it ideal for heavy-duty tow vehicles. The core of its strength lies in the tapered composite spring bars, which use Hendrickson’s LITEFLEX technology to provide the same holding power as steel, with five times the flexibility. That extra give absorbs road shock while still distributing weight evenly across the tow vehicle’s axles. It’s rated to handle tongue weights from 600 to 1600 pounds, covering a wide range of trailer setups. The single pivot point design simplifies the mechanism and eliminates the usual creaks and pops found in traditional systems. With the preset head angle, there’s no need to fine-tune or fuss with extra adjustments during install. It’s a strong, streamlined solution for drivers who demand precision and performance without added complexity.
