Weight Distribution Hitch with Sway Control and Integrated Lubrication

In this review of the CURT round bar weight distribution hitch, the bottom line is simple: tow vehicles and trailer owners who need a reliable, no-nonsense way to level their rig and reduce sway will appreciate this unit. It is best for owners of travel trailers, popups, and similar loads who want a heavy-duty hitch that spreads tongue weight across the vehicle-trailer combination and includes built-in sway control. The integrated lubrication system and robust forged spring bars give a quieter, smoother tow and reduce routine maintenance tasks.

Key Features

• Level towing: The hitch redistributes tongue weight to level the tow vehicle and trailer for improved steering and braking control.
• Integrated sway control: The included sway control bar reduces trailer oscillation so the rig tracks straighter at highway speeds.
• Continuous lubrication: The head has two grease zerk fittings for built-in lubrication, which keeps movement smooth and quiet over long trips.
• Reliable strength: Constructed with a formed steel head and 31-3/16 in forged spring bars to handle heavy trailer loads without deforming.
• Standard fit: Comes with a 2 in adjustable shank and a pre-torqued 2-5/16 in ball to fit industry-standard receivers and trailers.
• Corrosion resistance: Carbide black powder coat finish offers longer life against the elements for regular outdoor use.

Who It's For

This hitch is aimed at owners of medium to large trailers who routinely haul loads in the 10,000 to 14,000 lb range and need to maintain vehicle level and ride quality. Tow vehicle owners who prefer a durable, straightforward setup with a preinstalled 2-5/16 in ball and an adjustable 2 in shank will find this a practical choice.

It is not ideal for those towing only very light trailers or users who require an electronic sway-correction system; similarly, owners with nonstandard hitch receivers smaller than 2 in should look for a matching size rather than adapt this model.

Pros & Cons

Pros

• Built-in lubrication via grease zerks reduces friction and noise during towing.
• Heavy-duty construction and long forged spring bars provide dependable load leveling for heavier trailers.
• Integrated sway control noticeably reduces backend sway according to owners who used it on campers.
• Adjustable 2 in shank and pre-torqued 2-5/16 in ball simplify installation and compatibility.

Cons

• Weight and size make it overkill for light trailers and users seeking a minimalist setup.
• Installation requires handling heavy components; some users may need help aligning bars and head during setup.
