Video Transcript for Review of Reese - Weight Distribution - RP22225

Today we're gonna take a look at the replacement trunnion spring bar for the Reese weight distribution system. This has an 800 pound maximum tongue weight capacity. Now this is a replacement spring bar, it's designed to work on the Reese weight distribution system. This is a trunnion bar, it is hot rolled and tapered for nice superior strength and flexibility. The trunnion end, which is right here, is what will connect into the head assembly. And then the curved end on this side will connect to lift chains that will connect it to the lift brackets.Also, this spring bar could be used with the dual-cam sway control by Reese.

The curved end here is designed for use with that system. It does attach to the sway control arms. It will sit right on the sway control arm. Now we do sell that dual-cam sway control system separately on our website, it's part number RP26002.Now again, the tongue weight rating on this is 400 pounds to 800 pounds. And it is for a quantity of one spring bar.But that should do it for the review on the replacement trunnion spring bar for the Reese weight distribution system.

With this 800 pound maximum tongue weight capacity.

Replacement Trunnion Spring Bar for Reese Weight Distribution System - 800 lbs TW - RP22225

Average Customer Rating:  4.9 out of 5 stars   (49 Customer Reviews)

Replacement, cam-style, trunnion spring bar works with Reese weight-distribution systems with maximum tongue weight ratings of 800 lbs.


It’s always such a pleasure to work with etrailer. They have such great technical staff that helps me better understand what is the right item for my situation. They also have such a tremendous variety of RV related products. For me, Etrailer is simply the best I’ve ever worked with. So knowledgeable, courteous and professional.,


After using a tongue weight gauge I decided to drop from 1200# to 800# bars. I got them in 3 day. Thanks for the great customer service. I tell everyone about etrailer.


Extremely prompt and courteous service. Highly recommend.


I bought a new 27' travel trailer. Naturally, I needed a way to couple it to my vehicle safely. I have about ten years experience towing with a weight distributing hitch, so I was reasonably confident I knew what I needed when ordering a new one. I estimated that the toungue weight on my mew trailer would be in the 900lb range. I purchased a Reese dual cam package rated for 1100lb tw from Etrailer. I installed it according to the specifications and measurements outlined with the instructions. I found myself making adjustment after adjustment to get the trailer to "settle down" at speed. After trying everything from moving all weight possible to the toungue to changing the angle of the spring bars several times, I decided to weigh the tongue at a local truck scale. I was 503 lbs...... unloaded.... My spring bars were obviously waaaay to stiff to be effective. I ordered 800lb spring bars from Etrailer, installed them, and road tested them. The vehicle ensemble drove and handled like a dream. It felt extremely stable at interstate speeds. So take a lesson from your homework before you order your stuff.


exact replacement for previous bars factory shipping delay great communication from etrailer about the delay great service and price will surely use again for my trailer needs



still working great after a year will use etrailer again in the future


This is a great weight bar. Very simple to install and seems well built. I have been around other styles and choose the trunnion style for its ease of installation. Also, etrailer customer service can not be beat! They will not stop until your situation is resolved. This was the case on another product a friend purchased and I was hooked on etrailer since then!


I changed from 600lb bars to 800lb bars I still don't like the Reese Dual Cam hitch I thought maybe a heavier bar might make a difference they did stop the porpoiseng but still get some sway . that's why I only gave 3 stars nothing wrong with etrailer service and support .


Etrailer had the cheapest price I have ever seen for 800lb spring bars and free shipping. I placed the order at 5:30pm CST on a Saturday and the bars were at my house on Wednesday!!! Completely satisfied and will definetly look to etrailer for future trailering needs.


I have the “Old Style” Reese dual cam setup on my 2 horse trailer with large tack room bumper pull. I lost one trunnion style spring bar and the bolt on cam that’s attached to the underside end of the bar (see picture). Reese discontinued making parts for that system in the early 2000’s, my system was purchased in 1969. Looked everywhere with no success. I called Etrailer and for a new dual cam system and talked to Nicholas C, he advised me that the RP22225 spring bars would replace the old spring bars and cam. I had my doubts until he sent me a customers picture with the RP22225 bars on the same system I have, “A picture is worth a Thousand words”. Nicholas C And the Etrailer save me over $300 in unnecessary parts and a days labor setting up a new weight distribution system.


The new weight distribution hitch exceeded my expectations
Pricing was excellent,
Customer service was second to none!


I don't have much to say about the product, it is a good product well worth the money. I will say one thing about etrailer if you're looking for RV parts or anything related I highly recommend them they are very knowledgeable staff and fast shipping and the price was great.


Fast, easy, and efficient!


The service agent who helped me was very helpful. I lost a stabilizer bar on a trip from Missouri to Florida. The correct bar was delivered right to my RV site. I would recommend e-trailer for all trailer needs. Barry


I needed lighter spring bars for my lighter weight trailer. Etrailer had the perfect replacement for a great price.


Got exactly what I needed to replace an item you might think no one would want to steal right out of your own back yard. It appears in the product pictures as if the head end has an offset but it does not. The top and bottom pins are straight in line with the bar so that it can be used on either side.


Good product didn’t realize the chain and clamp weren’t included. All pictures showed the chain and clamp. Now I have to find those parts and wait for their delivery. A bit disappointed in all parts being separate. I lost my entire old one so I don’t have those parts available.

All of our replacement parts are sold separately just in case someone needs just that specific item and not the rest. The chain kit you need is Item # 3216, but I am not sure what you mean by clamp.


Got exactly what I ordered and it arrived when I wanted it, you can't beat that!
Thank You


works perfectly with my older Reese head unit.


We had broken a spring bar on a large rock while out of town, etrailer
quickly sent a replacement so we could make our trip back home.


Great service and product was excavated what I needed.. thanks


Shipping was prompt, as usual, and order was correct. The wd bars work as they should.


Had a trunnion bar delivered to my campsite while on vacation. Arrived very quickly. Reasonalbe price. Thanks a lot!


Great products, great company to deal with. Will use again in the future.


We lost this part during our 10 hour drive to Myrtle Beach. I ordered and it was delivered in 3 days right to our campsite.


Came on time have ordered from them in the past and have had Great sucess

  • Strait-Line Weight Distribution for a 2015 Ram 1500 and 2012 Windjammer Travel Trailer
    To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that the weight of anything loaded behind the rear axle of the tow vehicle. Tongue weight is typically 10 to 15 percent of the gross trailer weight so on a 7,200 pound trailer that would be 720 to 1,080 pounds so the 1200 pound system (which is actually rated for 600 to 1200 pounds)...

  • Replacement Single Trunnion Spring Bar For Weight Distribution System
    We do have many replacement spring bars like # RP22225 that are available as a single spring bar replacement. I have linked the page to these options for you so you can find the right replacement based on the brand as well as design of your weight distribution system. You will want your single replacement to match the other spring bar in your system for proper function.

  • Weight Distribution Recommendation for 2004 Chevy Silverado 2500 Towing 8,000 Pound Open Car Trailer
    Typically, you would want to choose a weight distribution system based on the loaded and ready to tow tongue weight of your trailer. Since your trailer will be carrying various types of cargo and have a different tongue weight nearly every time it is loaded, you will want to choose a system that has a large range and that can be adjusted to fit the load each time. Based on the empty and loaded weights of the trailer you provided, it is possible that the tongue weight will range from 200...

  • Availability of Replacement Trunnion Bars for Reese Weight Distribution System # RP66022
    Yes, we do offer replacement trunnion bars for weight distribution (WD) systems like the Reese # RP66022 that you referenced. You can click on the link provided to see all replacement trunnion bars for Reese and other brands. You will want to choose bars based on your system's tongue weight (TW) requirements. Each bar handles half of the rated weight capacity for the system, so for example, if your trailer TW is 600-lbs then the correct bar to use for a Reese trunnion system is part # RP22225...

  • Will New Reese Trunnion Bars Fit Into A Vintage 1970's Ball Mount?
    I spoke with Reese and they mentioned that the Replacement Trunnion Spring Bar for Reese Weight Distribution System # RP22225 will not work with your vintage ball mount, unfortunately. They mentioned they are incompatible because of the changes to the trunnion diameter and height. Instead, you may consider upgrading your system. If you're looking for a system that works with the Replacement Trunnion Spring Bar for Reese Weight Distribution System # RP22225, you'll want to use the Reese...

  • Can the Reese Dual Cam RP26002 Work On Straight Spring Bars?
    To get the Reese Dual Cam Sway Control System # RP26002 to fit, your spring bars will need to have a curved end that the chains are attached to. Kind of hard to explain, so I did include a picture of the end of the bar this fits. With that being said though, the # RP26002 will not be able to work with your current spring bars. You may be able to replace your current spring bars with something like the # RP22225, but you will need to confirm the weight capacity needed before doing so.

  • Overall Length of the Replacement Trunnion Spring Bar Part # RP22225
    The overall length of the Replacement Trunnion Spring Bar part # RP22225 from the end of the trunnion to the end of the bar is 33". I have attached a photo with this measurement for you as well. This spring bar is a direct replacement for Reese Weight Distribution Systems such as the Strait-Line Weight Distribution with Sway Control part # RP66073. It has a 400-800 lb tongue weight rating.

  • Will New Reese Spring Bars Fit in Place of Older Draw-Tite Spring Bars
    If your bars are labeled as Draw-Tite then the system is probably fairly old. There have been changes made to the heads over the years and the new bars will not fit in the old head. To change the bars you would also need to change the head with # RP58167. If you can tell me the approximate age of your weight distribution system I can determine if you can use the new bars or would have to also replace the head.

  • How to Identify Weight Rating of Weight Distribution Springs Bars
    Unless there is obvious damage to your weight distribution spring bars - rust, chipped-off material, or a clearly inappropriate bend - they should still be functional. On a trunnion style bar like Reese # RP22225 there is a bend at the trailer end of the bar which engages with the dual cam sway control. On a round bar system there are bends at both ends. The thing is you need to know the tongue weight they are rated for. Spring bars can look very much the same but be rated differently....

  • Which Style Spring Bars are Compatible with Dual Cam Sway Control Systems
    In order to be able to use a dual cam sway control like a Reese Dual Cam High-Performance Sway Control # RP26002 you will need to have spring bars that are bent at the end of them. Check out the picture I attached that shows which bars will work and which will not. For a curved bar that is in the same weight range as your Pro Series Trunnion Style Weight Distribution Kit # 49586 you would want a Replacement Trunnion Spring Bar # RP22225. This will allow you to use a Dual Cam Sway Control...

  • Replacement Head for Reese Trunnion Bar Weight Distribution System
    The Replacement Head for Reese Weight Distribution System # RP58167 is the correct replacement head for all of the Reese systems that use trunnion bars. To further verify that this will fit with your existing bars, I went out to the warehouse and pulled a compatible Replacement Trunnion Spring Bar # RP22225 so I could take a couple measurements. The pin at the end of the bar is 1 inch in diameter and the space from end to end is right at 4-1/4 inches, matching the measurements you took...

  • Where is Tongue Weight Info Usually Listed on Spring Bars of Reese Strait Line WD System
    On top of the spring bars there should be a sticker with the tongue weight rating for the spring bars listed. Hopefully it is still there! You could use a tongue weight scale like the part # e99044 to determine what your tongue weight is and from there determine what the best tongue weight range spring bars to use. Ideally you want your tongue weight to fall right in the middle of the spring bar range. The part # RP22225 has a tongue weight range of 400-800 lb. Since you need new brackets...

  • Troubleshooting Trailer Sway After Installing a Reese Strait-Line Weight Distribution System
    It is interesting that you are experiencing more sway with the 1,200 lb Strait-Line # RP66084. Typically what we see is that weight distribution (WD) systems that are overrated for their towing setup cause the trailer to be more stiff. Nevertheless you do need to swap out the bars for part # RP22225 which would then make your tongue weight range 400 lbs - 800 lbs and would be a better fit for your application. Other things to help combat sway are making sure that your trailer is properly...

  • Picking Out Weight Distribution and Sway Control for R-Pod 178
    Ideally the loaded tongue weight of a trailer falls in the middle of the tongue weight range of the weight distribution system. This figure also includes the weight of any cargo behind the rear axle of the tow vehicle. So if your dry tongue weight (unloaded) is 250 lbs you could pretty easily find yourself over 400 when it's loaded and if you have cargo in the truck. Another option that I think would be ideal would be to go with the lower rated version of this system part # RP66082 which...

  • Replacement Lift Bar for Reese Weight Distribution System
    When you say lift bar, I am unsure if you are asking for a the handle for lift brackets or if you are referring to the spring bars. For the handle for lift brackets, you will want # RP58162. This provides leverage to ease lifting a positioning of the snap-up chain brackets. If you need spring bars, you could use # RP58114 for tongue weights up to 800 pounds. For trunnion bars like # RP22225 there are also different capacities. I've linked the page to all these options to assist,...

The part number includes 1 bar, so you will want 2 in order to upgrade your system. Since you are happy with your current weight distribution system, upgrading will be a matter of preference.

  • Can Reese Strait Line Weight Distribution 66084 be Converted to 66083
    Yes, you would just need to replace the spring bars of the # RP66084 and you would have basically the # RP66083 as that is the only difference. For spring bars you would then just need a quantity of 2 of the part # RP22225.

  • Which Spring Bars Would be Best 600 lb or 800 lb For Dodge Ram 1500 4x4 and Starcraft Hybrid Antiqua
    When determining the correct spring bars for your trailer you will need to take into account the weight of gear loaded behind the rear axle of the truck and the additional tongue weight loaded in the camper. I believe larger is better but in your case the 1,200 pound bars are too stiff if they are causing the ride to be uncomfortable. I would go with the 800 pound spring bars, item # RP22225, since you will have gear behind the rear axle and gear to load into the camper. With 350 pounds...

  • Parts Needed to Increase the Capacity of Reese RP66082 Strait-Line Weight Distribution System
    In order to increase the capacity of the # RP66082 to 800 lbs, you'd replace your existing spring bars with part # RP22225. The # RP22225 replacement trunnion spring bar has an 800 lb capacity. This bar would best be used on trailers with a fully loaded and ready to tow tongue weight ranging from 400-800 lbs. For a ready to tow tongue weight from 600-1200 lbs, use part # RP66009. The bars are sold individually. I've linked you to some helpful FAQ articles about weight distribution.

  • How to Determine Tongue Weight when Choosing a Weight Distribution System
    The trailer should have listed somewhere on it or in its literature the tongue weight that it should be. Typically tongue weight is 10 to 15 percent of the gross trailer weight but not always (this is especially true on boat trailers since the back of a boat weighs more than the front). It sounds like you are adding the vehicle weight or part of the vehicle weight to the trailer weight but this is not correct. You would add the weight of cargo LOADED behind the rear axle of the tow vehicle...
