Create a stable ride for your tow vehicle and trailer with a weight-distribution hitch. Adding spring bars to your towing system applies leverage, which transfers the load that is pushing down on the rear of your vehicle to all the axles on both your tow vehicle and your trailer, resulting in an even distribution of weight throughout. The result is a smooth, level ride, as well as the ability to tow the maximum capacity of your hitch.
The tongue weight rating is the most important factor in determining which size weight-distribution system you should use. If the bars of the system you choose are rated too high for your setup, they will create a rigid ride, which can result in a bouncing trailer. If, on the other hand, the bars are not rated high enough, the system will be unable to properly distribute the weight, rendering it virtually useless.
To determine the proper weight rating for a weight-distribution system, you must first determine your trailer's tongue weight. Then add to that the weight of the cargo behind the rear axle of your tow vehicle. These two measurements make up the tongue weight rating for a weight-distribution system.
Integrated Dependent Sway Control
The Steadi-Flex weight distribution system works to stop trailer sway before it begins. This is achieved in 2 ways. First, the system head is designed to firmly hold the spring bars in place to provide tight resistance and help ensure that your trailer tracks behind your vehicle. Second, the spring bar brackets that mount on your trailer's frame produce friction with the bars whenever any side-to-side motion occurs. This keeps the bars from moving, also helping to hold your trailer in a straight line.
System Head with Steel-on-Steel Friction
The head of the Steadi-Flex system firmly holds the spring bars in place at the hitch point. This tight hold helps to keep the bars from moving, which in turn helps to ensure that the trailer is held firmly in place behind your vehicle. If any sway or side-to-side movement does occur, the spring bars will move only slightly inside of the system's head. This steel-on-steel contact produces frictional resistance to limit further side-to-side motion of the bars, limiting the motion of your trailer in the process. The Steadi-Flex head is wider than most weight distribution heads. This design allows for greater surface area for the spring bars to move against. This makes it easier to produce the friction that resists sway.
Sway Control Brackets with Automotive-Grade Friction Material
The spring bars attach to the trailer frame with fixed, sturdy steel brackets. They sit on top of the brackets instead of being suspended by chains like the bars that are on traditional weight distribution systems. Chain suspensions typically allow a good deal of side-to-side play in the system. Because the Steadi-Flex has brackets in place of chains, that unwanted movement of the spring bars is eliminated. This helps to keep your trailer in line behind your vehicle. In addition, these brackets create friction to limit any side-to-side movement that may occur. When each spring bar on the Steadi-Flex system moves within the bracket, it rubs along the surface of the bracket, creating friction. This resistance limits the movement of the spring bar, thus preventing further side-to-side movement of the trailer.
Most systems with sway control brackets use bare steel brackets to create friction with the steel bars. Steel-on-steel friction typically causes a much louder ride, and it can result in wear and tear on the brackets themselves. The Steadi-Flex brackets, on the other hand, are lined with automotive-grade friction material. This material is more abrasive than bare steel, which allows more friction to build up faster and easier. The long-lasting friction material also reduces the banging noise created by the bars hitting the inside of the steel brackets. This provides a quieter ride while towing.
Fast, Easy Installation
The Steadi-Flex system is easy to install and set up. On the trailer side, simply clamp the spring bar brackets around your trailer's frame. Then prepare your vehicle by sliding the included shank into your 2" x 2" hitch receiver, and bolt on the head. The system head can be easily adjusted to achieve the proper angle and optimum leverage for your specific setup. No drilling is required to install this weight distribution system.
Head Tilt Adjustment
The Steadi-Flex system uses the traditional washer-style adjustment method to achieve the perfect tilt. Controlling the head tilt helps you to fine-tune the leverage and maximize the amount of tension in the whole system. To adjust the tilt, simply slide washers onto the adjustment pin and insert the pin into the head assembly. To increase the angle, add a washer. To reduce the angle, remove a washer.
Tapered Spring Bars
The spring bars of the Steadi-Flex system slide into the weight distribution head for quick, easy installation. With a tapered design and hot rolled steel construction, these bars offer superior flex to evenly distribute the weight between your tow vehicle and your trailer.
The bars easily pin into place inside the system head - no need to torque or re-torque any trunnion bolts to adjust the tension. With fewer parts to manage, installing and maintaining the Steadi-Flex is simple.
Adjustable, Clamp-On Brackets
The spring bar brackets simply clamp around your trailer's frame - no drilling required. These brackets are designed to be positioned 27" to 32" back from your coupler and they can fit a wide range of frame sizes and can even be used on a trailer with a bottom-mounted coupler.
While other brackets use relatively thin L-pins to secure the spring bars in place on the brackets, the Steadi-Flex system uses steel pieces that are almost as wide as the brackets themselves to secure the bars. These retention brackets easily pin into place once wrapped around the spring bars. As a result, you can have greater piece of mind knowing that the spring bars are secure and less likely to rattle around inside of the brackets.

Friction in brackets and in head works to prevent and correct trailer sway. Chainless brackets with automotive-style friction pads hold spring bars firmly in place to help keep trailer in line with your tow vehicle. Adjustable shank included.This thing was awesome. No sway from high bridges,and semi trucks. Went over some very high tall bridges no sway there either. Track true on my Tacoma and Rockwood Roo 19. Once we got it dailed in. Distributed weight perfect front was spot one.
Works great (Jeep Wrangler pulling 3500LB load), as with all friction based WD hitches there is some squeaking when turning corners but that is as expected. Deliver and price was good. Would by again.
I've towed a few thousand miles with this hitch on my Astro Van (properly equipped) pulling a 15ft open deck car trailer(~4000lb loaded with 450lb TW). I have been very happy with this purchase. The anti-sway system on the WDH works very well even with my smallish tow vehicle. No issues when towing in crummy weather with strong winds and driving rain, the hitch handled wonderfully. The sway control is fairly quiet when making sharp turns or backing up.
Great product!
Working well for my Boat Trailer with surge brakes. I'm happy I went with this 600/6000 LBS version instead of maxing out the 400/4000 LBS version on my 380/3700 LBS rig. I'm now towing legal again since down-sizing my tow vehicle to a 2015 Ford Flex, AWD, V6 EcoBoost, Even with the factory tow package the Flex is only rated for 200/2000 without WDS, but 450/4500 with WDS. I did a couple trips to my local lake before WDS (30 mile round trip via 45 MPH roads) and the Flex felt safe for that distance/speed, but it had a lot more trailer jolt and was not quite as stable as my old GMC Envoy XL. The WDS has improved the towing stability and ride well beyond my expectations, and is now even better then towing was with buddy's full-size Pickup. I did have to use a Pole-Tongue Adapter (RP58393), and customize the adapter mounting to my trailer, but I can already tell this added hassle and expense will be well worth it for the long-haul trips I do a few times a year.
We bought the 6k GTW- 600 TW which is slightly more than we needed but it was a fairly easy installation. The truck pulls the camper so much smoother and safer my husband even let me drive on the highway!
Very happy with hitch system. Has made a difference in towing our camper. Easy to install, and easy to use for each trip.
Works great. I am able to tow a 3,500 lb travel trailer with a Jeep Wrangler Rubicon. Jeep sits level. No sway from wind or emergency lane changes. Works fine on mild off road trails. Hook up only takes about 8 minutes longer once the process is well known.
Was easy enough to install. If I ran into any snags, it was because of me, not the product. E- Trailer provides excellent products and amazing service. Best value for the money.
I really like the Reese Stedi-Flex system. I use it with a 2.0" ball on a Tundra when towing a small 3500lb travel trailer. I don't need it for load leveling, but it keeps the trailer in control on the highway. I have a heavier duty Reese system for towing my 8,000lb sail boat trailer (where I do need leveling) and it also works very well for anti sway
Still can't figure out how to level the trailer! To undue the spring bars I need to raise the trailer and truck very high! Deciding whether I should just tow on the ball and not use this setup. Not very happy

Wed be happy to help you get that figured out. Take a look at the set-up video Ive linked for you. If you still have questions after that, please let us know.
This has been a lifesaver for our Jeep Cherokee (non-Grand) towing a 4k# trailer. Prior to this, towing felt sketchy above 50 and downright unsafe above 70. With this, things feel secure at any speed.
Just remember to take the bars off if you're doing any sort of off-roading.
I really only have 2 gripes, hence the 4-star review:
1. The pins connecting the trunnions tend to spin a bit while driving, which can result in the cotter pin getting mangled. I had to buy a bolt cutter to remove one once and now carry them and spare cotter pins as a result. I'm very careful to always align the pins with the bars but it doesn't stay that way. It seems they could improve the design.
2. The pins tend to wear with sharp edges, making inserting and removing them very difficulty. I've already had to file the edges down once and expect to have to do it every season or so.
Both of these are very manageable, though, and are a small price to pay for the increased safety and comfort while towing.
Recommendation by etrailer was perfect.
Easy to install
Trailer pulls with no sway, wandering
Or porpoising.
Take the recommendation and go with it.
They know what they are doing.

Great
Was used to tow a 3500lb. travel trailer with YJ Jeep with a 5.3ls engine conversion. Set bars to a very light setting. Trailer tows very nicely. Great product. The braking system for anti-sway is one of best on the market. Replaceable brake pads are the way to go, just like in tow vehicle.
WOW! I have a Lance 1995 24 foot trailer that was balanced but swayed above 55 mph. I researched the solution on this site and based on everything suggested I purchased the Reese Steadi-Flex. I formerly had a Husky round bar unit that did not address the issue. The order had a minor delay so I was contacted by etrailer. They gave me options but assured me what I bought was the best. So I waited. Glad I did. I cannot believe the difference. There is absolutely no sway whatsoever with this unit. After a long drive on Hwy 99 I found the speed had crept up to 70! Oops. Still in perfect control. Had I done this before I would have wound up in a ditch!
This thing is literally a life saver and I am no longer worried when I have to tow with it. Super cudos for staff at etrailer. You have my business from here on out. Also I want to comment on the complaint about the bars being heavy. Not so. I am sixty eight and recently damaged both thumbs so my lifting is limited. (btw, old guys SHOULD NOT use a jackhammer!) The old round bar Husky was heavy, these straight steel bars are not. Much easier to set this unit up. I will never drive with my trailer again without the Steadi-Flex. Thanks etrailer!
Hitch works great. Sometimes use it without sway bars (for short trips), but noticeably less sway and bobbing with sway bars attached. Used with Ram 1500 and Lance 1995 trailer.
After a few trips, one of the friction pads cracked and separated. Etrailer was very helpful getting it replaced quickly. No problems in the subsequent trips.
I just bought a new trailer that is 7 feet longer than my last and heavier and I now have a truck instead of an SUV so I needed to get a new weight distribution hinge with sway control. etrailer had all the best brands at the best price and delivery was fast. Unfortunately that's all I can comment on so far. I'm not picking up the new trailer till mid April, so I can't comment on how well it works or show pictures. I'll update later.
I searched many different companys on line. I kept going back to Etrailer for many many questions regarding various other hitches and weight issues. They were extremely helpful with all my questions and very patient. Plus once I placed the order I received my order two days early.
They are the best in customer service and price. I would differently use them again.

Very happy with my purchase, etrailer is a fabulous company to deal with , great installation videos for this item as with all the products I’ve purchased from them over the past few years.
Very happy with product. Was fairly easy to install after watching video. I use mostly for long distance interstate driving. It makes the truck and trailer feel like one unit.
Excellent customer service and helpful installation video online. I was disappointed in the quality of the product (not etrailer's fault) due to poorly tapped holes and paint in the holes that made assembly slightly more difficult than should have been required. Just be aware of this so you don't cross thread any bolts and strip out the threads!
quick ship had it in three days expecting hitch to work as intended.
Great product, easy install. Fast shipping, thanks
Delivered very fast. Great price and great customer service. Will definitely be buying again

Used this product for about 1800 miles. I couldnt be happier. The sway control is great. Ive been in CBBT, Hampton Rd Tunnel, tall brides,and just roads. It has performed great. My one complaint is I tried to buy pads from Etrialer for this hitch and could not. I think I actually got a spare set from reese.
