Today we'll be reviewing part number RP66075. This is the Reese Weight Distribution. It's going to be a Strait-Line Weight Distribution System with Sway Control, that's going to be a Trunnion Bar design. This right here are going to be the sway control, the dual-cam sway control system. The entire system is designed to evenly distribute weight over the axles of the tow vehicle and the trailer for stability and control. It's going to create a more level ride for both the tow vehicle and the trailer. It's going to feature the automatically self-adjusting, self-centering sway control, it's going to work in a variety of situations. When it comes to straight-line movement, the cams are actually going to lock in the position to hold trailer steady despite the crosswinds. When you're cornering, the cams will automatically unlock and slide to allow full-radius turns and then when you have those moments where you can't avoid a sudden swerve, the cams actually seek a straight line angle to help stabilize the trailer. The heavy-duty system is ideal for commercial and industrial use.
It is designed for heavy-duty towing with 2-1/2" x 2-1/2" trailer hitch receivers. The sway control system is going to bolt onto an A-frame trailer tongue and it's going to attach to the lift brackets using the chains. So real quick, you can see how this portion would swing up, it's going to attach to your trailer frame. It's going to have a set screw at the back and then it's going to have two screws right up here on the other side of the bracket, so on the outside portion of the frame of your trailer. All the hardware that you need to get the sway control system installed is included in the bag and so it has everything that you're going to need to get it installed to the trailer. It's also going to feature the lift brackets so one end of the chain is going to be on the lift bracket, the other end is going to be attached to the dual-cam sway control system and again, it's going to be the same on both sides. The sway control again, is going to bolt on to the A-frame trailer tongue. It's going to attach to the lift brackets using the frame.
Great thing about this system is this is not going to use any U-bolts or platforms, so that way you don't have to worry about it interfering with frame-mounted items such as gas tanks, toolboxes or generators. The trunnion bars are a hot rolled designed and are tapered for superior strength and flexibility. So the bars will flex appropriately over uneven terrain for a controlled, even ride and then the sway control cams are going to provide attachment points for the spring bars, so you can see how it sits over the dual-cam sway control system because it has that tapered in. The head assembly is going to feature a forged, raised ball platform that's going to eliminate the need for a raised hitch ball. The adjustable spring-bar tension is very easy to take advantage of. All you have to do is just change out the links in the chain so you can adjust it as needed; that way you can make those tuned adjustments simply by increasing or decreasing the links that you have set right here. I had it set like that and if I need to increase the tension or make some adjustments, I can simply just take the chain and I can switch the link that I have hooked on to the lift bracket. Another great feature about this system is you can easily get the tilt that you need with the serrated-washer design here at the head assembly, so you don't to worry about piling on washer after washer.
It's going to feature two washers right here. They have teeth in them that dig in to the teeth on the head assembly. Its going to allow you to get that angle and tilt that you need very easily. Real quick while we're back here, it's also going to come with a shim; you can use this when you need to fill any gap between the head and the hitch bar. It would slide right in here, you'd run the bolts through the holes and you'd get that to line up right in the .. there's a lot of detailed information on that in the instructions that comes with the weight distribution system. The system is going to include the sway control cams, the head assembly, the lift brackets, the spring bars, the lift chains.
It's also going to feature a snap up handle that way you can get the chains up in the place. It just goes over that portion right there. It's going to allow you to lift it up into place that way you can attach the pins that I already have installed. Then when you need to disengage the chains, you can use that leverage handle to bring the chains back down and easily disconnect them from the life brackets. The adjustable shank and the trailer hitch ball are going to be sold separately. This is going to use a hitch ball with threaded shank and it's going to need to be 1-1/4" in diameter. This is going to offer a towing weight of 1,000 lbs to 1,700 lbs; with a gross towing weight of 17,000 lbs. Again, it is designed to fit a 2-1/2" x 2-1/2" trailer hitch receivers thats rated for use with the weight distribution system. When choosing the shank, we offer a couple of great suggestions underneath the related products, on the right-hand side of this product's product page. You can check those out, that way you can get the appropriate shank that you need to get the weight distribution head attached to it if you don't already have one. When positioning the left brackets, you're going to want to position them about 30" back from the hitch ball, so you'll do that measure on each side of your trailer frame. The brackets are going to go over the frame and then you're going to tighten down the set bold back here and get it nice and secure up against the frame of your trailer. Keep in mind that it's going to require approximately 5 1/2" of space along the trailer frame to get the lift bracket positioned and it will not fit trailer frames wider than 2 1/2". Once again, all the hardware that you need to get this installed it's going to come with it so you don't need to purchase anything separately to get it mounted. The only thing it doesnt come with is it does not come with the hitch ball or the adjustable shank. Everything is made from a nice steel construction, very heavy duty. It's going to last a long time. It's got a really nice powder coated finish on so it's going to stand up really well against rust and corrosion, for riding you many years of use out of the system. That's going to do it for our review of part number RP66075. This is the Reese Strait-Line Weight Distribution System with the Sway Control. .

The best hitch for anti-sway! It kept everything in line! Even when gusts of wind would pitch trailer and send an F250 truck out of control into center divider! THANK GOD FOR THE FORD'S TRACTION CONTROL SYSTEM!! We sold the pull trailer and moved on to a 45' 5th wheel! What a difference. I will never own a pull trailer greater than 24ft ever again.
I purchased and set this up between my 2017 F250 diesel and a 12K, 37’ travel trailer. I use it in conjunction with the Gen-Y torsion hitch. The combination of these together is the most incredible tow solution I have ever had in place. My wife is happier to experience less load transfer back into the truck on bumpy roads and I am ecstatic to have much less to no white knuckle sway issues through the windy flats and as well as passing between semi trucks. This is a bolt on so I recommend having exactly the correct drill size and type available, as I used a step drill that reamed out one of the 4 holes initially. After speaking to the manufacturer, they said I could just bolt straight through the frame with a longer bolt and nut. The brackets are already formed to accommodate that option as well. In short, I will never tow with a different setup. Only down side is it tows so well that I forget sometimes the trailer is back there on long hauls. ;)
This is a super heavy hitch for a large heavy camper. Take your time setting up the sway control bars and it will reward you with probably the best performance that will be had with a heavy, long bumper pull trailer. The hitch is a little noisy during turns, but that doesn’t bother me. My F250 4x4 handles our 32’ Jayco toy hauler with no drama after finding the right chain tension. Very happy with the hitch. Thanks Lori at etrailer.
I've had this product installed for about a year. I race motorcycles and installed this on a 35' toy hauler that use at least once a month. Hooking it up to the truck is simple with the sway bars, and it helped to greatly reduce the sway travelling down the road. Toying something that large without a system like this is a safety issue, and I feel much better toying now with it on.
unbelievable hitch.....works amazing
Performing better than expected. No sway at all with 12,000 lb. trailer.
The package came on time and is complete. Good company.
Outstanding Company.
Our family has been using the Reese Dual-Cam sway control (which comes with the Strait-Line WD setup) for over 20 years. The sway control arms, which bolt to the trailer A-frame, have cam arms which ride in the "saddles" on the ends of the WD bars. If set up right on installation, about the only time you would experience enough sway to give you "white knuckles" is when you are driving in a tornado! (& if that happens, GOOD LUCK and GOD BLESS!) The Hensley hitch is probably better (have never owned one), but the Reese Strait-Line is close to $2,000 cheaper, and none of our family has ever felt like we had a need for a hitch/sway control setup more expensive or better than the Reese, and most of us pull some really long and heavy conventional travel trailers. High crosswinds will move the entire rig sideways, but the trailer stays centered behind the truck. The "bow wave" of 18-wheelers overtaking us at a high rate of speed on multi-lane highways will push the rear of the trailer sideways as the bow wave passes. But no steering correction is needed. The additional couple of hundred pounds of pressure put on the WD bars when the trailer moves sideways and causes the sway control cams to move out of their "saddles" pushes the sway arm cams right back down into their "saddles" on the end of the WD bars, which, if the hitch was adjusted right on installation, means that the trailer is once again centered directly behind the tow vehicle. The Strait-Line can probably be beat, but we're never going to spend an extra $2000 to find out. If you have any control problems with the Strait-Line, it is either not set up correctly, or the wind is such that you shouldn't be towing anything, anyway. Even a Hensley hitch can't keep the entire combination of truck/trailer from being pushed sideways by very strong winds, nor can a 5th wheel hitch, because I've seen 5th wheels lying on their sides more than once, and during my working career I pulled high-profile or gooseneck heavy equipment trailers all the time. There are times when you just really shouldn't be towing large travel trailers, or any high-profile trailer.
I used this for the first time Pulling a 22 foot travel trailer with a Jeep Gladiator. I hit high winds 20+ gust to 40, heavy rain. I have towed thousands of miles and was ready for anything NO Sway at all felt solid I had people tell me I could buy a cheaper hitch YOU GET WHAT YOU PAY FOR
OK, I waited to write this review until I had an opportunity to really use this product. We just completed a 950 mile camping trip around Colorado. We went up and over mountains, around curves, and traveled in the interstate. All I can say is, WOW! I wish I had purchased this years ago. We pull a 7000# travel trailer with a new F150 EcoBoost. Before installing this we were pushed around in windy canyons, semis and dealt with sway descending the mountains. This product is the real deal. I can safely travel on the interstate at speeds up to 75 MPH thanks to this product.
I added this hitch setup to a 2023 F250 - 2023 Hawk horse trailer with tack room and I could not be happier. It allows the truck to maintain its proper ride height and eliminates all the minor steering corrections needed when driving at highway speeds on less than perfect roads. Proper setup is key and takes time but the outcome is well worth the time and money investment. This is the 2nd straight line set up I have had on my vehicles for horse trailer towing - first was for an Expedetion with a smaller trailer which provided me with a decade of confident trailering.
Installed this on a 2016 Silverado 1500 2wd dbl cab pulling a 2016 northland 30ft travel trailer. I was having the typical sway issues with crosswinds and passing big rigs etc. I am very pleased that this hitch solved the problem. Good quality product. I installed it myself and I had to buy about $100 in larger wrenches and a good quality step drill bit.
Awesome weight hitch! I pull a 28" camper with this hitch and its really nice not having to stop and break down the hitch before backing up the camper. I have about 3k miles on this setup and absolutely love it. Its also easier to store when not in use because the chains stay attached to the cams on the a frame of the trailer and not attached to the bars. So the bars arent as heavy. Thanks again etrailer
I had this hitch installed at a local RV specialist shop as I didn't have access to a large enough flat and level area. The cost was about $225. When I picked up the truck and trailer for a test drive, the trailer tracked true behind the truck and I never felt any sway. The load leveling feature helped keep the truck level and I always felt I was in complete control. The only down side to this product is the noise it makes when taking sharp turns. The metallic popping noise are scary at first but I was expecting them. Overall I am very pleased with the performance of this hitch and would recommend it.
The product was not only a perfect physical fit for my truck and travel trailer, but it it works so well I no longer drive with white knuckles. The etrailer support team worked with me to figure out my real needs versus my preciously rookie "wants" which were somewhat uninformed wants. My Trunion Bar WD Hitch with Optional sway control makes ZERO noise in use or backing up, nor does it impart any felt knuckling.
I use this to pull a 3500lb travel trailer behind my 2007 BMW X3. We just completed a 4000 mile road trip with this hitch, traveling on every difficult windy curvy hilly mountain and coastal road from San Diego to Vancouver and back.
The PROS: Easy to install, attach and detach. It distributed the weight well, and we had no problems with sway.
The CON: It moans and groans on turns like an old man that forgot to take his pain meds. Even when it’s been lubricated.
I've been very happy with the system that we got, we put almost 7,000 miles on it in 2017 and it rode great. I added a secondary friction sway control to compliment the control provided by the leveling bars and cam assembly and over those miles it never felt uneasy. A couple of times we were in some pretty good cross winds and I would notice enough to put two hands on the wheel but the rest of the time it was almost easy to forget we were towing a 28' trailer.
I'd definitely recommend spending a little time at your local Cat Scales to find out your specific truck / trailer and tongue weights, but this hitch and distribution assembly gave us the ability to tune the tongue weight into right where we wanted by the selection of the right link.
The peace of mind the overall control that it provided going down the road is well worth it.
This hitch is much easier to set up, hook up and unhook than the hitch it replaced!
I have been around Reese Hitches for 50+ years. They are hard to beat!
Works great on a older 28 ft. 6000lb. restored Airstream with a F150 4x4 with anti sway electronics. Without we could only go about 55 mph and the trailer would sway. The truck would warn us to slow down. The install was a bit complex we were not too sure of the angle of the hitch but we followed directions and it works. We traveled about 6k miles on two trips. It stopped the sway even at 70mph . Many a giant truck flew by at 80+ it started to sway but the bars prevented it. Backing and tight turns are no problem. Adjusting the chains require some work and disconnecting, reconnecting a pain. would highly recommend to any one .
My last strait-line weight distribution kit w/sway was sold with my travel trailer. These with dynamic sway control have made such a difference in many tricky situations, times when I was traveling in ice in a snow storm, or rain storms, I have always felt in good control with this system. Buying the same system again was a no-brainer. E trailer has helped out a lot with the best tech support and has answered so many questions for me. Great group over there.
