Video Transcript for Reese Weight Distribution RP66009 Review

Today were going to review part #: RP66009. This is the Reese replacement trunnion spring bar for the Reese weight distribution systems. This is a replacement spring bar that works with the Reese weight distribution systems. This is a trunnion bar. At this end you can see the trunnion that the spring bar is inserted into. The trunnion bar is hot rolled and tapered for superior strength and flexibility.

You can see it tapers that way. The curved end right down here, as you can see, this is designed for use with the dual cam sway control which we sell separately. Thats part #: RP26002. This part does include the one spring bar. The tongue weight capacity on this spring bar is 600lbs to 1,200lbs.

It is made in the USA. That should do it for part #: RP66009, the Reese replacement trunnion spring bar for the Reese weight distribution systems.

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. 760441

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! 652650

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. 454333

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.

I've owned 3 travel trailers and would not want to tow without the reese strait-line weight distribution system with sway control. 149923

  • Solution for Reese SC Weight Distribution Trunnion Bar Needing Replacement
    Thank you for all of the pictures. I do have a solution for you but when I reached out to my contact at Reese he said that you have the older SC weight distribution (WD) system and there aren't any replacement bars that will fit your application. The Pro Series trunnion bars have a different attachment configuration which keeps them from being interchangeable with the Reese systems. For your setup you either need to replace the entire WD system or you can use the Replacement Trunnion...

  • Replacement Reese Trunnion Spring Bar for System with 1,200 lb Tongue Weight Rating
    Thanks for the picture and info of your spring bar. Based on that I can confirm that the correct replacement is the part # RP66009 that you referenced.

  • 1,200 lb Tongue Weight Reese Strait-Line Weight Distribution System Recommendation
    By the time you piece together your new spring bars # RP66009 and a dual cam sway control kit # RP26002 you would be better off just replacing the entire system with a Strait-Line System part # RP66074. You will need to use the shank you currently have. This will allow you to sell your current setup to offset the difference instead of leaving you with extra parts that wouldn't do you any good.

  • Dimensions of the Replacement Trunnion Spring Bar for Reese Weight Distribution System RP66009
    I will try to provide the dimensions you need. If another dimension is needed let me know and I will be glad to get it for you. Overall length = 33 inches Length to the spring bar detent = 29 inches Width and height of spring bar = 1-3/8 inches Width of Trunnion at Spring Bar = 3 inches Height of Trunnion at Spring Bar = 2-3/4 inches Trunnion ends = 1 inch diameter Overall Trunnion Height = 4-1/2 inches

  • Selecting Replacement Trunnion Weight Distribution Spring Bars for Reese WD System
    The best-performing weight distribution/sway control systems are those that prevent sway from occurring in the first place, rather than trying to stop it once it starts. Reese Dual-Cam systems are among the better options in such a set-up. It is absolutely possible to swap out your existing trunnion spring bars to new ones with a more appropriate weight capacity for your trailer's tongue weight. The way to do this is to measure your trailer's tongue weight with a scale like the Sherline...

  • Replacement Spring Bars for Mid-90s Reese Weight Distribution System
    I may have a solution for you, however the Reese Weight Distribution System that you have is no longer in production and the design has changed a bit since then. It is possible that the Reese Replacement Trunnion Spring Bar # RP66009 will fit but it will depend on how your current setup works. If the head on your hitch uses spring bars that are held in with clips that are dropped in the head, then these bars will not fit. The issue is that the designs have changed on both the trunnion spring...

  • Are Replacement Spring Bars Available for Old Draw-Tite Weight Distribution Head 7120
    The weight distribution head you have was made obsolete on 2/10/2011. I spoke with my contact at Reese/Draw-Tite and the current springs bars will not fit the head that you have. In order to use new bars you would have to replace the whole system and get new additional bars for different weight trailers. The bars you have are probably rated for a range of 600 to 1200 pounds. Bars are rated for 200 to 600 pounds, 400 to 800 pounds, 600 to 1200 pounds, and 800 to 1500 pounds. It would...

  • Reese Trunnion Bar Compatibility with Weight Distribution Head
    As long as you have a Reese trunnion style weight distribution head like # RP58167, you can change out the spring bars for your needs. For a 1200 lb total tongue weight system you can use the Replacement Trunnion Spring Bar for Reese Weight Distribution System - 1,200 lbs TW # RP66009. I've linked the page to your other options based on total tongue weight. You will notice the Trunnion and Pin come with the bars on these replacement spring bars.

  • Replacement Spring Bar and Head Recommendation for 1,200 lb Draw Tite Weight Distribution
    I wish we had replacement parts that would work, but the bars you have aren't compatible with the current bar designs made so it's going to come down to you replacing the head and the bars. So for bars you would need the part # RP66009 which has the 1,200 lb capacity you need and then for a head you would want the part # RP58167.

  • Will New Reese Spring Bars Fit a Draw-Tite Weight Distribution Head
    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. But depending on the age of your existing system it may be possible. What I recommend is to get the new spring bars since you will need them either way, # RP66009 for one bar, and if they do not fit the head then you would need to replace...

  • Replacement Weight Distribution Head and Shank for Spring Bar with 22210E Marked on It
    I phoned my Reese Representative, who tells me the 22210E part number you provided comes back on an 800 lb spring bar used with the Reese SC Weight Distribution System, which has been discontinued. If this is indeed the system you have, the replacement head and shank are still available as part # RP54980. The shank provided has a 6-1/2 inch rise or 1-1/4 inch drop when used with trunnion type bars (like the Reese SC used). If you need a different rise/drop, I've linked you to the rest...

  • Replacement Trunnion Ends for Weight Distribution Spring Bars
    Yes, you can replace the trunnion ends of your spring bars. The Replacement Trunnion and Pin for Reese 1200 - 1600 lb Trunnion Style Weight Distribution, item # 58097, is the replacement part. You will need two ends and the roll pin is included with each. If you have the lighter weight distribution system you will need the Replacement Trunnion and Pin for Reese 600 and 800 lb Trunnion Style Weight Distribution, item # 58098, for the ends of your spring bars.

  • Trunnion Bars for Use in Reese Dual Cam and Dual Cam High Performance Weight Distribution Systems
    The trunnion-style spring bars used in Reese Dual Cam weight distribution systems, both the standard dual cam and high-performance dual cam systems, are the same length. Trunnion spring bars are selected not based on length but by weight capacity. Weight distribution systems for a trailer should be selected based on the trailer's fully-loaded as-towed tongue weight. It is important to proper performance that the spring bars used have the correct amount of tension to provide the proper...

  • Replacement 1200 Pound Spring Bar for a Reese Trunnion Style Weight Distribution System
    The Reese Replacement Trunnion Spring Bar, 1200 p0unds, part # RP66009, will work if your old bars were rated at 1,200 pounds. If your old bars were rated below 1,200 pounds and are over 3 years old, part # RP66009 will not work. If you have the older style head with smaller Trunnion ends you will need the Draw-Tite and Reese Replacement Weight Distribution Trunnion Style Head, part # RP58167.

  • Will New 1,200 Pound Reese Spring Bars Fit a 5-Year-Old Reese Weight Distribution System
    The system that you bought from us 5 years ago was # RP66541 and it is still the same now as it was then! This means that you can replace your 800 pound spring bars with the 1,200 pound bars. For a single bar it is # RP66009. You would need 2 of them total.

  • Should Spring Bars on Weight Distribution be Upgraded if Bars are Underrated for Tongue Weight
    Yes. If the spring bars you're currently using on your weight distribution system aren't rated high enough for your trailer's tongue weight then they won't be doing their job properly. If you can load your trailer to reduce the tongue weight without dropping it below 10 percent of the trailer's total weight that may be another solution. You may be able to replace just the spring bars themselves instead of the entire system. Let me know which weight distribution system you have I...

  • Are Weight Distribution Spring Bars Universal or Brand-Specific
    All weight distribution system parts, except for the shank component that fits into your hitch, are proprietary and brand-specific. You could mount a Curt WD head on a Reese shank (or the reverse) but the spring bars and other parts need to be from the same maker as the head assembly into which they will be installed. I linked our main page for trunnion spring bars. Select bars based on the brand of system and the trailer's fully-loaded tongue weight. Ideally the total TW will fall near...

  • How to Set Up the Correct Amount of Chain Links for Installing a Weight Distribution System
    How many links get used when installing a weight distribution system really depends on the tongue weight of the trailer. Basically you set up a WD system so that the tow vehicle sits as level as possible when loaded. Changing the amount of links used (or the angle of the WD head), allow the system to apply more or less spring bar tension on the setup. You want to apply the correct amount so that the tow vehicle sits as level as possible. You won't want to use less than 6 links. For...

  • Replacement Spring Bars for a Reese Weight Distribution System
    As long as your total tongue weight does not exceed 800 lbs, you should not need heavier spring bars. Your total tongue weight will include the loaded and ready to tow tongue weight of your trailer plus the weight of any cargo that you load in your tow vehicle behind the rear axle. If you find that your total tongue weight will exceed 800 lbs, then you will want to step up to the next size spring bar. The only available 1,200 pound replacement Spring bars from Reese are for the Strait-Line...

  • Solution for Nose of Trailer Sagging With Weight Distribution System Still Installed
    If you have trunnion spring bars only rated for 500 lbs that is the issue. You mentioned the trailer weighing 7,400 lbs which means you are looking at a tongue weight much higher than what your trailer is rated for. You need to replace your spring bars with the part # RP66009 which have a tongue weight range of 600-1,200 lbs. You'd need a quantity of two of these bars. Once set up properly these will work well to reduce the sag you are experiencing.

  • 800 Pound Springs Bars Cause a Stiff Ride with Trailer with 630 Pounds Tongue Weight
    The 600 pound spring bars would be rated too low for 630 pounds of tongue weight and the system would be ineffective. The 800 pound bars are the way to go. Try to lower the trailer end of the spring bars by one chain link for less tension and that should help with the stiff ride.

If it is the old style system, the bars will not fit in the head. The head you would need is # RP58167. This is the new style head that is compatible with the 1,200 pound bars.

There are not currently replacement round bars in that capacity available from the manufacturer.

  • Will the Reese Weight Distributing Spring Bars Work with a EAZ Lift Weight Distribution Head
    I have no information on whether the spring bars on your hitch can be replaced with the Draw-Tite Round Style Weight Distribution Spring Bars. The best option for you is to purchase a new weight distribution head and spring bars for your shank and hook-up brackets.

When choosing spring bars you will need to select bars that have proper capacities for your trailers tongue...

  • Replacement Spring Bars to Upgrade Tongue Weight Capacity on Reese Strait-Line WD System
    Since the loaded tongue weight of your trailer will very likely creep up over the 800 pound tongue weight capacity on your existing Reese Weight Distribution System like # RP66083, I do recommend replacing the spring bars to increase its rating. The Replacement Reese Trunnion Spring Bar # RP66009 will work perfectly for your new trailer. This spring bar has a tongue weight capacity of 600 to 1,200 pounds, so will work well even if you fall toward the lighter tongue weight possibilities...
