Video Transcript for Review of Reese Replacement Weight Distribution Trunnion Spring Bar - RP66009

Hi, there. I'm Michael with Today, we're gonna take a quick look at this Reese replacement weight distribution trunnion spring bar. This is going to replace a cam style spring bar that will work with your Reese weight distribution systems with dual cam sway control like the one you see on the screen there with the 12,000 pound gross towing weight and the 1,200 pound tongue weight. This trunnion bar is constructed of a hot rolled and tapered steel, so it is going to provide superior strength and flexibility. It does have that 600 to 1,200 pound tongue weight so it is going to work as a direct replacement for that model of weight distribution system that I just showed, or if you have a similar weight distribution system with that Reese style and you're wanting to replace the spring bar to either go up in weight or down in weight to meet your application's needs, this will be a great option for that as well.

You can see it does have the curved end here that it is designed for that dual cam sway control system. So make sure you're getting the right one for you. You can see it does have the trunnion design up here as well, so it's gonna work really well. And because this is a direct replacement from Reese, you can trust that he is gonna fit right in place of your original. No worries about compatibility or anything like that.

So that completes our look for today. Again, I'm Michael with Thanks for watching.

Replacement, cam-style, trunnion spring bar works with Reese weight-distribution systems with maximum tongue weight ratings of 1,200 lbs.


I always deal with etrailer. The only reason why I possibly might not buy my trailer and towing needs from someone else is if etrailer doesn't carry them!! I've used the Reese Strait-Line equalizer and sway control system for 20 years, and bought the Reese Strait-Line for my son and sister-in-law. I prefer it to other systems such as the "Equalizer" brand system because the Reese "dual-cam" system is the only one which has a center detent position on the "bent bars". If the trailer moves to one side or the other, it must first put several hundred pounds more tension on the "bent bars". This tension forces the trailer to move right back to the straight-behind position without any steering wheel movement at all. I already have these 1200 lb. bars on my Strait-Line hitch and sway control. My sister-in-law is getting a new trailer with heavier tongue weight, and these bars will replace the 800 lb. bars she has now.



The heavier-duty spring bars have worked out well on my sister-in-laws new, heavier travel trailer. No problems at all, truck trailer tow level.


I have owned a Reese weight distribution system now for almost four years that I use on my 28' Pace Car Hauler Trailer. I have been extremely satisfied with the performance of the system and the recommendations and continued on-going service from the folks at

Still Works As Advertised


Season is still a month away, but they do fit fine should do the job!


Miss R took my order.........

1200 pound Reese trunion bars came quickly. I was impressed with the heavy duty box and good packing.

Great price and first class service. My box trailer needs some more items. I will definitely buy them from Etrailer.

Thank you

Larry G.


All is well. I wish that I had upgraded to the 1200 pound bars trailer tows so much better now.


Installation picture


Folks at Etrailer are wonderful. Thanks for all the instructional videos that help us with our hauling needs. I needed to replace my 800/10,000 lb trunnion bars with 1200/12,000 bars when purchasing a heavier trailer. Etrailer got the new ones sent out to me in good time, and FREE SHIPPING on these heavy dudes. I notice the new ones are slightly (maybe 1/2 inch) longer, so will need to review how they hook up to my Reese Dual-Cam anti sway hitch.


Great service and a great product. I purchased my 2nd Reese straight line load distribution/anti-sway system. The first one the dealer installed. This time I installed it myself and it went without a hitch. (pun intended). I did have to exchange the spring bars due a math error on my part and the shank for the system apparently escaped from a box. But not a problem. Etrailer staff had them to me in 2 days and I was on my way on schedule. Great job Bryan!


Excellent service!
Korren was a delight
to deal with - courteous, knowledgeable about the product.
Order shipped promptly and arrived a day early!
I will definitely look to e-trailer whenever I need a part.



Excellent product


Great replacement part. Lost my old one


In a previous review I gave a poor rating because the trunnion bars were missing from the original order. It took customer service two days to determine they needed to send me replace bars. However the representative was professional and once the determination was made the bars shipped right away and were delivered within days. I now have the entire Reese w Weight Distribution System and it is a great buy for the money.


etrailer is a great place to buy from, I've been a customer since 2007. Great price, fast, great customer service, plus plenty of online help. Reese weight distribution systems make trailering much easier and safer. I've owned 3 travel trailers and would not want to tow without the reese strait-line weight distribution system with sway control.


Talked to sales, ordered correct parts, installed the new bars. They work excellent. $180 for new heavier weight distribution bars vs. $788 for dealer recommended hitch. I will do business again. Thanks, Ken


Product was exactly as illustrated on website. The website was very well organized and easy to navigate. Thanks for making it simple. I have already recommended this website to others.



Still works great


Replaced the 800 TW bars on my Draw-tite 7902 with RP66009 1200 TW bars. Worked perfectly. Moved the lift assemblies further back slightly as the bars are just a little longer than the 800 TW bars


Exactly what we needed when we upgraded to a heavier camper. Everyone at E-trailer was helpful in making our decision as usual. Great product and fast shipping!


The service was excellent. The shipping level was upgraded at no charge and the Spring Bars arrived in perfect condition. I received personal emails at every stage of the transaction which makes a real difference if there was a problem to deal with. Because of the early delivery I was able to reset my Weight Distribution setup this weekend and I am ready to go camping again!


Did not use the product yet however it looks like it will do the job service was fantastic recieived it very quick



Works fine


Just what we needed to "clean up" our Reese WDH system w/ Sway cams when we moved it onto our new trailer.


I searched for replacement spring bars to replace my reese 750# bars, etrailer had just what I needed I orded the reese 66009 on friday and received on monday the next week Super fast shipping and the parts fit perfect Thanks etrailer


This was a replacement part and works perfect. Tech was a lot of help in getting the correct part.



Replacement Trunnion Spring Bar for Reese Weight Distribution System - 1,200 works perfect every time use them on a car trailer.


Trunnion bars arrived in 2 days, packaged very well. Fit my existing hitch since I upgraded from 800# to 1200# bars. Great service from etrailer!


Item arrived prompt and well packaged. Thanks!


The trunnion bars were as expected. The part I like the bestimate was etrailer had them to me quick! I needed them before this weekend and they came well in advance.


Replaced my old 600lb spring bars with these 1200lb spring bars. When I ordered them the rep answered all of my questions/concerns while on the phone. They arrived two days after ordering, and I couldn't be happier!
Thank you Etrailer!


Awesome experience with etrailer. Price was well below what my dealer could have gotten it for, and the shipping was very fast. I highly recommend this company.
