Stop trailer sway before it begins with this dual-cam sway control. Cams lock in place on either side of trailer to supply consistent pressure, helping to prevent and correct sway. Works with weight-distribution systems with cam-style spring bars.
Note: Dual-cam sway control cannot be use with surge-type trailer brakes and is designed for Class III, Class IV and Class V hitches only.
Reese's dual-cam sway-control system stops trailer sway before it begins. This is a significant improvement over traditional friction-style controls, which help to correct sway only after it has already begun. This specially designed system uses unique sliding devices called "cams" to suspend the spring bars of your weight-distribution system. One end of a cam bolts onto your trailer's frame, and the other end attaches to the lift bracket via the lift chain. This type of sway control is compatible only with cam-style weight-distribution systems. The spring bars of these systems are designed with rounded, hooked ends that sit in the cams. The controlled placement of the spring bars keeps your system secure while still allowing enough movement for free, easy interaction between your trailer and your tow vehicle.
During basic, straight-line towing, the cams lock in place and hold the trailer steady by applying constant, consistent pressure to both sides. This keeps the trailer from swaying in crosswinds. When you go into a turn, the cams unlock and slide to allow a controlled, full-radius maneuver. If you swerve suddenly, the cams will give to accommodate the movement while still working to obtain a straight angle, thereby maintaining control of the trailer.

Today we are going to do an install of part number 66067 we have a full size van and an enclosed toy hauler and as you can see here it is kind of sloping down pretty bad. We will go ahead and install weight distribution to help straighten things out. To begin our install we have to uncouple the truck and trailer, get the trailer level and get the measurement off the ball mount. At this point we can go ahead and pull the van out of the way and get a little more working room. We will go ahead and take out the ball mount and then then go ahead and measure for a rise or if needed for the shank for the weight distribution. What we are going to do is measure from the bottom of the coupler to the ground and that is 22 inches. We will do the same thing for the vehicle. We will measure from the top of the hitch on the vehicle to the ground. Roughly it will round off to 18 inches so we will need to raise it 4 inches.
Now we just pick out a shank with a 4 inch rise to it. Next we will go ahead and loosely install the head assembly on our shank and adjust it as close as we can to the couplers 22 inch height. We will go ahead and install our adjusting washers. To adjust the tilt of the head you just turn these washers here to make it go up or down as needed. Once you have the hitch set the height you want, if it is in between always go with the next higher slot up. Because it is better to have it up to take care of any vehicle squat when you put the weight on the trailer hitch. Go ahead and install the ball on here. Turning it sideways will make it easier to tighten down. We will go ahead and tighten up the bolts that hold down the head assembly. Next we need to get a few measurements on the van before we put the weight on there. We will measure from the top of the wheel wells then down to the ground and note those. Ideally we want to have about a 1/2 inch of sag overall and the rear measurement should not sag more than 1/2 inch. Looks like the back wheel is 36 and the front wheel is 35. We will go ahead and attach our chains to our spring bars here. They just attach them with a U bolt. Go through a couple of washers and lock nuts. It does not have to be super tight either just tighten them down a few threads past the nut will be fine
The next part is to go ahead and put the trailer back on the truck and get it back to original ride height. We will go ahead and install our swing bars and locate where our lift lock brackets need to go. What you want to do is go ahead and pull up the chain as straight as possible until it gets vertical. Then line the lift lock bracket just with it. That will give us plenty of clearance for this little ferrying here. Once we have our alignment set we will go ahead and put a few marks on here just so we know where to place it when we put it back. We will take it off and then put our set bolts back in and reinstall it. Once you have it set you want to tighten down your set screw tightened right until it touches then about a half turn it will fall into place. Then go ahead and repeat for the other side. Now at this point you have the trailer and the van coupled up. We will go ahead and raise both of them with the trailer jack. Rise it back up to original trailer height. Then we will install our chains and see how our dimensions come out on the wheel wells. One note is you should have a minimum of 5 links showing. So I think we will be on 7 maybe. We will go ahead and pull it up and repeat for the other side. Now we will take the tension off of the jack and let the bars do all the work and check our measurements. Go ahead and measure here 35-1/2. About a 1/2 inch difference which is just fine. Then 35-1/4 which is pretty close. The rear was okay but the front did not settle like it was suppose too, in fact it went up just a little bit. Also one detail we will look for is that the spring bars if you notice should be parallel to the bottom of the tongue.
In this case they are actually pointing up towards the tongue. Which is not right, they should be pointing straight or down. So to remedy that you will have to tilt the whole head assembly one notch then see what we have there. This requires disassembly then we tighten it back up and try it again. With adjusting it one more notch down and we have gained about an 1/8th of an inch overall in front which is fine. Then on the back we settled it about a 1/2 inch. So a load is being distributed across the vehicle and trailer. That concludes the installation of part number 66067 from Reese. What we have here is our dual cam high performance sway control. Part number 26002 from Reese. We are going to install it on an existing weight distribution system. That system would be the round bar system from Draw Tite. We do have to make a few modifications to it. First off we have to take the spring bars back off and disconnect the chains there on the end. Then the chains get reattached to another bracket and get reinstalled. This is our new bracket we are bolting our chain too. It just goes through a loop and then through here. All we need is a minimum of 2 threads past the nut will be good enough. Then repeat for the other one. Next thing we do is make sure the yolks are centered on the threads here. Basically you want to make sure they have even threads on both sides. You pretty much tighten until they stop. Then go ahead and mark the frame to mount these onto. Next is to install one of our spring arms to do a trial fit. What you want to do is make a center point 18 inches from the center of the ball out to the end of the frame.
As you can see we already did that all we want is the center of this bolt to line up with this mark. Then you want the this part here about 1/2 inch in front of the indent. When you bring up tension this round ball part will rise up into the indention. Once you are certain it will fit decently we will go ahead and line it up and just mark our holes out. We will drill these out with a 1/4 inch first then come back through with a 7/16 bit. We can go ahead and just start threading our bolts in the front end without the bracket first just to get them started. Then we will go ahead and install our main bracket. We are going to go ahead and install our bracket now to the sway control. When you get the bolts tightened down snug then go ahead and tighten them up about a 1/4 turn thats all the torque you need. Now we can go ahead and install our set screw here on the back of it. Before we can install our set bolt we have to install this jam nut first about 3/4 of the way. Then we will lock it in place with the jam nut. Before we hook up our chains we need them back off these nuts now. Get a free range of movement. Then we can go ahead and put up our lift lock brackets. We will go do that for the other side also. Next we need to go take it on a test drive making left and right turns, about 20 degrees. So that you can make sure that sway control cam fits properly into indention on the spring and then we will snug those nuts back down and tighten them good. After you have had your test drive and things are sitting they way they are suppose to go ahead and tighten down these nuts right here. You want to get them torqued down so we can get the lock washer flattened out. That concludes our install of part number 26002 from Reese. The dual cam high performance sway control.

A difference you can feel... After trading our old camper, towing the new one home was a scary experience. I read tons of reviews about different sway control devices and decided on the dual cam. As we pulled on the highway for our first trip, I was a little nervous as I saw the first tractor trailer coming to pass me. To my amazement, no sway!! My truck and trailer did move over a little but it was together and without sway. Nothing can substitute for a properly loaded trailer and adequate tow vehicle but the dual cam is a great supplement. Installation was fairly easy with basic tools (ratchet, wrench, tape measure and drill) and etrailer.com has several videos that complimented the instructions very well. Their customer service is the best in ecommerce; plenty of communication and always available if needed. Thanks for making our vacations a little more relaxing!! 111702

I have been using (2) friction sways when towing my 32ft enclosed car trailer. Now with this new dual cam unit, it eliminates the sway actually before it gets started. I feel like I have more control of my truck now when pulling my trailer. No more sudden movements when a semi truck passes by. Great product and easy step by step instructions. I would defiantly recommend this over the friction type sway controls. Thank You etrailer.com for your awesome customer service from start to end as I received an email confirming the order was placed, then when shipped, then a follow-up after I received it. The shipping was very fast and the product was packaged very well. 93481

I installed the weight distribution set on our 27 foot Arctic Fox trailer. The instructions were well written, the set went on as described and the system works very well. We now have about 10,000 miles on it. We have a 20 foot cargo trailer, I wanted to use the sway control in it. I ordered the extra parts to be able to change trailers relative easy. Vince was very helpful and got me the correct parts. Delivery was prompt and as forecast. Good place to do business, nice people that know the product. 149929

Sway unit arrived promptly. It's 119 degrees on the Mohave Desert these days, so I won't be installing it until the weather cools. It is to replace the old unit I trashed this summer while making a very tight turn in an Aspen, CO parking lot. Sometimes the customer is at fault!!! Had to drive back to CA with no sway control and it wasn't fun with some really bad winds coming down I-15. It'll be back on the hitch before the next trip. 50968

I received the Reese High Performance Sway Control with 1200# trunnion bars for my 2013 Keystone Outback travel trailer. The directions were straight forward and installation wasn't too difficult. The biggest part was adjusting the cam arms, and making sure the measurements were correct for the cam placement on the trailer tongue. This system works beautifully, and I couldn't be happier. The price was reasonable too. 57592
FAIRLY EASY TO INSTALL AND ADJUST. TOOK ABOUT 1 1/2/HOURS. SUGGEST YOU USE COBALT BITS FOR DRILLING. ALSO NEEDED WASHERS BECAUSE RADIUS OF THE BRACKET WAS DIFFERENT THAN THE FRAME. BRACKET SHOULD SIT FLUSH ON THE BOTTOM FRAME. TOOK A TRIP AND FOUND NO SWAYING WHEN TRUCKS PASSED BY! NEED MUCH LESS OF ORIGINAL CHAIN, SO MAKE SURE YOU ADJUST LINKS SO THAT FRONT WHEEL WELL HEIGHT IS THE SAME AS BEFORE. 171070
My husband had no trouble installing and they have worked fine. Our trailer wasn't extremely heavy to begin with so we didn't have a real sway problem, but since we were planning a long trip on I-95 we thought it would be a good idea since we'd encounter a lot more big trucks. We never even noticed the passing of a big rig. Our camper just glided along behind us without so much as a shutter. 99287
I had a friction type on my 30 foot trailer that the rv dealer put on , then found out after doing some research that it is not enough for a trailer that large or of that weight !!!! Great rv dealer 30 years in this and they know enough to be dangerous !!! So took it off put this on and took it out on the hwy , Great !!!! So much better !!! took a little while to set it all up but worth it ! 83773

I have a 2014 Premier Bullet 31 feet long about 7,000lbs. I have Reese weight distribution and had a friction sway control. Have a huge problem with sway. I now purchased a new high performance control. This still did not help. I drove 35mph to keep the rig on the road. I don't know the next step. Etrailer gave me great service though I still have a problem. 138508

Haven't installed the sway control yet but, if they perform as advertised I will be very happy. I paid for 3-5day shipping but they did not arrive for 7 days. Had hoped to install over the holidays but now will have to wait until the weekend. 167733
