This setup is made for short-tongue trailers that don’t have room for standard-length bars. The trunnion-style spring bars measure 28-3/8" long and are built from solid forged steel for strength and durability. They evenly distribute tongue weight across the axles for a smooth, controlled ride and help keep steering steady and the trailer level, even with heavy loads.
If your setup pushes into the heavier range, this system is ready for it. It’s rated for up to 15,000 lbs gross towing weight and 1,000–1,500 lbs tongue weight, giving you room to tow to your hitch’s maximum capacity. The powder-coated steel resists corrosion, and the included shank and hardware make it a complete, ready-to-install kit.
Getting the right tension is simple. Two set screws let you pivot the head without stacking washers, so you can tilt the hitch ball away from your tow vehicle to add more spring bar tension. It’s quick to fine-tune and locks in place securely once adjusted.
Out of the box, this system handles weight distribution only—but it’s built to easily accept a bar-style friction sway control unit (Curt 17200, sold separately). The sway control adds friction-based resistance to help bring the trailer back in line when wind or passing trucks push it off course. You can decide later if you want to add it, no need to replace the hitch.

Some setups require you to remove parts before reversing, but not this one. You can back up or make tight turns without disconnecting anything, which makes parking or navigating campsites a whole lot simpler.

You mentioned that it was completely worn out and I wanted to ask if you could explain in more detail? Would you be able to send a picture.

I do not have any pictures. I scraped it last fall. The pockets where the arms go in the hitch were completely worn out almost completely through.

When there is excessive wear in the trunnion socket in he head unit, it indicates that there may be an overload on the bars or that its needs more lubrication. You will want to make sure trailer and vehicle are as level as possible. If not level then you will want to re-measure and adjust until it is. The spring bars need to have a heavy, fibrous grease applied to the top section of each spring bar.
Do you have a question about this Weight Distribution Hitch?

That hitch has been great! Our approximate 7,000lb., 27 ft. enclosed race car hauling trailer, is now very stable. With the bars and hitch we were using, which were much to small, it was a real handful, now you hardly know it is back there!Great piece of equipment!
