Review on Get Ultimate Towing Stability With CURT TruTrack Weight Distribution Hitch & Sway Control - Up To 10K Capacity, 2-Inch Shank & 2-5/16-Inch Ball - In Sleek Black Design by Jim Polacek

I've been using this on my 3500 lbs single axle travel trailer for over a year now, and it works awesome. The sway control is a huge help, especially because the single axle trailer would sway a lot while driving. With this system attached, it is so much better, I could not be happier! I keep it lubed up with a few shots of grease here and there, which is easy to do with the lube zerks, and I just use a finger to physically put a little grease on the metal ball detents. It was easy enough to install (took me about an hour) and is higher off the ground than the other chain models. This makes it very easy to get in and out of the driveway without scrapping the ground. With this system, the low spot for ground clearance is the actual part that hooks up into the back of your truck, so if your truck is low on ground clearance from the back, you might have trouble getting in and out of the driveway. For me, this was an all in one awesome purchase (sway control, weight distribution, bobbing control) and I would buy it all over again.The only thing I will say is this looks to be a bit of a lighter duty system than most others. This is fine for me, as my trailer is only 3500 lbs. Keep this in mind before purchasing. If you have a heavy duty trailer, buy a heavy duty system. If you're anywhere close to the 10,000 lbs weight limit it states, go up and get a heavier duty one. This is a good rule of thumb for just about anything with towing. This would also explain why some of these other idiot reviewers broke their systems. That and don't do a 90 degree turn with this on ur rig. If you need to do some crazy maneuvers, just remove the bars and put them back on after (it only takes a couple minutes).UPDATE: It’s 2022 and still going strong. Last year I even sold my single axle 3500 lbs trailer and now have a 6500 lbs double axle trailer. Everything still works like the day I bought it. New trailer is higher off the ground so I flipped the L-bracket and installed myself again. Curt just makes great products.
