Video Transcript for Reese Weight Distribution RP54980 Review

Today we'll be reviewing part number RP54980. This is the Reese Replacement Head and Shank for Reese Weight Distribution Systems with Trunnion Bars. It's going to feature a forged raised ball platform that's going to eliminate the need for a raised hitch ball. It's also going to feature an adjustable shank. It's going to have six different mount holes on it. Center-on-center, those are going to be separated by an inch and a quarter. The adjustable shank can be used in either the drop or rise position. The mounting hardware and the serrated washers are included so you're going to get the two large bolts.

You're going to get two serrated washers, one on each side. You're going to get the lock washers and also the nuts that go on the bolts. The serrated washers are great to have because they're going to allow the head to pivot without adding any additional spacers or washers to the unit. This portion here is going to slide into the 2-inch x 2-inch trailer hitch receiver. You're going to push it in until you get your pin holes to line up with one another and then you'll need to install a hitch pin and clip or a hitch pin and lock. Those are going to be sold separately.

You can find those on our website so you can check that out for more options if you don't already have one. It's going to give us a tongue weight capacity of 1500 pounds with a weight distribution trailer weight of 15,000 pounds. We take a measurement from the distance of the center of the ball hole to the center of the hitch pin hole. Since there are two pin holes, I'm going to measure directly in between those pin holes. That's where we're going to get a 14-inch measurement from. With it installed in the rise position, you're going to have a rise of 6-1/2 inches and in the drop position, which is how it's set up, is going to offer a drop of an inch and a quarter. The shank bar length is going to be measuring from the end of the shank to the back of the upright portion of the shank and that's going to give us a measurement of 12-1/4 of an inch. This is made from a solid steel construction.

It has a really nice black powder-coated finish on it so it is going to stand up really well against rust and corrosion. That's going to do it for our review of part number RP54980. This is the Reese Replacement Head and Shank for Reese Weight Distribution Systems with Trunnion Bars. .

Works as described. Much better than antique version I had. The shaft inserts 2 1/2 inches further into the receiver hitch. The access to tighten nut for the ball is straight in - very good. The ball height adjustment places the ball at correct height. Arrived the day promised. Happy customer.


This year I moved my wife and I accross the continental United States to start a business. In order to do this, I had to borrow my father-in-laws awesome trailer, and with it, everything else I needed to move all our worldly possesions from Colorado to North Carolina.

After arriving in Raleigh, we had the unfortunate reminder that life isn't fair when our trailer hitch was stolen off the truck. So while we moved everything into the new place, I had to scramble around trying to find the part we needed to return the trailer. I had ZERO clue about what had been stolen, and the terminology was a massive hurdle.

I came here, on the good advice by the manufacturer themselves, and they answered my question so quickly. I had a back-and-forth with the wonderful customer service people (multiple, amazing customer service people. Dealt with 3, and all 3 of them were helpful, friendly, informative, and patient with my lack of trailer knowledge.).

So I was missing what turned out to be a Trunnion and Shank, and not only did they help me find this peice of equipment, but they even had the cheapest price! (I know, I looked everywhere)

They got the equipment to me quickly, with free shipping, and it only took a week to get to me! Now I'll never have to tell my father-in-law and maybe wait till christmas to make a fool of myself. Thanks etrailer!


Got exactly what I ordered and in a timely manner.
I have ordered other trailer parts from etrailer and have found them to be very reliable.


As always etrailer has come to my rescue for needed parts and supplies for my travel trailer and pickup truck. I crack the old shank on my 21 years Reese WD system and they were the most affordable and super fast with shipping. Now I could get back on the road and head home out west. You guys are awesome.


It was just what I needed to replace the old worn head and shank. It appears to be built to handle the load of our racing Kart trailer.



It works fine


This hitch replaces an older Reese draw bar and hitch of the same type which I retired due to its age. The draw bar was 25 years old, the head was 10 years old. I'm using it in conjunction with a Reese double cam sway control to tow a 36 ft., 9000 lbs. travel trailer. I'm towing with a GMC 3500 Duramax dually and the set-up is so stable you don't even feel that you are towing. I towed in a 40 mph cross wind and was amazed by the stability. Before the GMC 3500 I used the same hitch with a Suburban 2500, which exhibited some sway in strong wind conditions with the 36 ft. trailer, but towed very stable with a 32 ft. travel trailer.


Was very pleased with how quickly order was delivered. Had obvious approximately 1/8" gap between Weight Distributing Head and hitch bar where bolts go through. Instructions said "Use the shim provided when needed to fill any gap between Weight Distributing Head ..." No shim included. Called etrailer and was told shim kit is optional and on back-order. Seems like shim should be included if needed, or at least a note in product description. RP54980 Replacement Head and Shank. Be advised, may have to make shim.


We were at a complete loss when someone stole our Reese hitch while we were in Yuma, AZ. Reese parts department gave me the part number and Etrailer had it in stock. I spoke with Lori late in the afternoon and explained our situation. Lori, the parts department, and shipping went above and beyond to get it out that day. Long story short, we had it on in a couple days. This is not the first time I've worked with Etrailer, just the first I shared my experience. They always come through for you.


Etrailer had a very fair price and free shipping at the time to boot. Everything was packed very well and email confirmations were sent every step of the way.


I recently ordered a new truck and needed new hitch components.
I asked around with local auto parts distributors but did not get any help.
Draw Tight directed me to their on line distributor. Christine was very helpful. Guided through parts I would need. I placed order and parts were delivered in three days. Excellent service and reasonably priced.


I attempted to keep it local and went to buy it from a trailer hitch specialist up the road. They referred me to etrailer. Winning pricing, winning delivery time. Thank you!


Both items I've ordered in the last couple of weeks arrived very quickly. There were both in the 50lb plus weight range and was packaged correctly. The items were heavy steel hitch hardware so, not much to go wrong there. is awesome.


I needed this hitch for my camper since we were leaving in 6 days to go on a two week vacation. I got the right hitch and got it even faster than promised! Excellent service.


Exactly what I ordered and I got it very fast. High quality and heavy duty.



Ive had the hitch for a year now and I pull a 3-1/2 ton camper It works great. No problems at all great price and value for such a heavy duty hitch. I only wish I would have bought the smaller ball for the friction brake at the same time. I couldnt find one local and had to order it as well.


Great service, parts arrived when expec ted


Works exactly as expected. Good quality. Fast order fulfillment from etrailer.


Good product. Priced right. But more than that, much thanks to Brittany for keeping on contact and making sure I was informed: My order was significantly delayed due to a back order, she let me know every detail with my order. Thanks a ton, Brittany


Great product. Works as expected. Great quality.


Ordering was easy and all my parts arrived faster than expected.


the part works and the nuts were installed to spec's prior to shipping
thank you, I will order from you all again next time


Quick shipping, great price and excellent product


Great service




Very nicely built. A lot of adjustment available to the product.

  • How to Confirm Compatibility of New Head Assembly with Bars from Older Weight Distribution System
    Weight distribution systems can often be fitted with different spring bars to allow an existing system to be used with a new trailer that has a different tongue weight. However, sometimes the design of the latest systems can differ from older units and make the new parts not compatible with the old. It really comes down to the specific system you have, its age, and whether or not the maker has decided to alter the design since the time your unit was produced. The Reese Replacement Head...

  • 800 Pound Spring Bars for a Fastway E2 Weight Distribution System
    If your tongue weight is 667 pounds then I recommend the 800 pound spring bars, # FA94-02-0899 for a single bar on an E2 round bar system or # FA92-02-0899 for a single 800 pound bar for trunnion bar systems. If you were to use 600 pound bars the system would be overloaded and it will not be effective. I have included some helpful links on weight distribution for you.

  • Shank and WD System Head Availability as Replacement Parts
    Sounds like you are in need of a weight distribution shank and head assembly. Without knowing what brand you have it would be hard for me to make the proper recommendations. Most shanks are universal though. They typically will have 3/4 inch diameter holes that are spaced 1-1/4 inches apart measured on center. I attached a page that has all of the shanks we offer as well as an FAQ article that details how to pick out the correct rise/drop ball mount for a setup. I also attached a link...

  • Recommended Weight Distribution System for a Trailer w/ a 1,040 lbs Tongue Weight
    Thanks for the picture! It looks like a Reese head for a weight distribution system but I have no idea what it is without a part number which means I can not give you an accurate answer or even an educated guess as to its capacity. You may want to check the spring bars if you still have them for serial numbers or markings stamped into them. The best I can do is recommend a replacement weight distribution system since you already know what your trailer's tongue weight is. For a trailer...

  • Weight Distribution Recommendation to Replace a Fastway E2 System
    We do not carry Fastway products currently so we don't have a head and shank that would work with your E2 trunnion bars and brackets. You would have to find a Fastway dealer to track down the correct parts to match what you have. A Curt head wouldn't work. By the time you replace those parts you might be better off just buying an entire new system. The best way to pick out a weight distribution system is to base it off of the loaded tongue weight of the setup when it is loaded and ready...

  • What Size Trunnion Bars To Fit On Reese High Performance Trunnion Head with 63970 Shank, # RP54980,
    Yes the Reese High Performance Trunnion Head with Shank, # RP54980, comes with the, # RP58167, trunnion head. You are going to need to measure the bar thickness you have. The earlier bars were 1-1/8 inches and the later bars are 1-3/8 inches. You mention the 22210D that is stamped on your trunnions. That is the casting number which does not pertain to the part numbers, so I would not worry about the casting numbers. The Reese Replacement Trunnion and Pin, # 58098, uses a spring bar thickness...

  • What is the Gross Trailer Weight of the Replacement Head and Shank, # RP54980
    The gross trailer weight for the Replacement Head and Shank, # RP54980, is going to be 15,000 pounds. When choosing a weight distribution system you will need one that has a tongue weight capacity range than encompasses the trailer tongue weight when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the towing vehicle. I have included a link to our FAQ article on weight distribution and sway control.

  • Is it Possible to Use a Weight Distribution Replacement Head as a Simple Adjustable Ball Mount?
    I contacted the manufacturer and it technically can be used as an adjustable ball mount, relying on the non-weight distribution ratings of your hitch receiver. This may not be the most visually pleasing option, but it will work. It has a rise of 6-1/2 inches or a drop of 1-1/4 inches and the distance from center of hitch pin hole to the center of the hitch ball is 14 inches. The hitch ball does not come with this replacement head, so you'd need to purchase a 2 inch ball like # 40038 or...

  • 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...

  • Does 27 Foot Trailer Need A Friction Sway Control Unit
    I'm assuming you're describing the weight distribution head, which would look like # 58333. This weight distribution head has a hole on each side of where the trailer ball would attach for mounting a # 83660 friction sway unit. If your trailer is having sway problems caused by crosswinds or turbulence caused by oncoming or passing traffic, a friction sway unit can help. For trailers longer than 26 feet, we recommend two units, one on each side. If your weight distribution head only has...

    I checked with my technical contact at Reese and he said that as long as your trunnion bars are the Reese branded bars, like part # 66010, they can be used with the Replacement Head and Shank for Reese Weight Distribution Systems, # RP54980. He also mentioned that that newer bars cannot be used in older heads that have Latch Pins, like part # 58025, for securing the spring bar, see photo.

  • Can I Use a Weight Distribution Hitch on a Large Aluminum Trailer
    When it comes to using a weight distribution hitch on your aluminum trailer, the main concern isn't only the interaction of the two metals but a lot of occasions the aluminum frame isn't strong enough to be used with a steel weight distribution system. You will want to consult with the trailer's manufacturer to determine if your trailer can be used with a weight distribution system. For a trailer with a larger frame size you would need a weight distribution hitch that used chain hangers...

    Sorry to hear about your truck being stolen. It sounds like your Reese trunnion weight distribution system's shank and head assembly were both probably stolen. Your 1970s trunnion bars WILL work with replacement head part # RP54980; I confirmed this with Reese. This includes the head and 2-inch shank; for a 2-inch ball use # A-90 or for a 2-5/16-inch ball use part # 19286.

  • Fit of Replacement Trunnion Spring Bars on Reese Weight Distribution Head 54936
    I checked with my technical contact at Reese on the weight distribution head part number 54936 and this item is no longer active. None of the current trunnion bars will work on that head so you'll need to choose a new system for your new trailer. When you select a new system for your new trailer you will want to measure the trailer's fully-loaded TW using a scale like etrailer # e99044 (or using the methods shown in the linked article). To this you need to add the weight of anything in...

The shank that is included with this head and shank kit is rated for towing capacities up to 15,000 pounds, and this shank is the same shank included with your original trunnion-style weight distribution system.

  • Weight Distribution System to Replace Older Reese 1,000 Pound System w/o Available Replacement Parts
    I do have a solution for you but what you currently have is an older system and unfortunately there are no longer replacement parts for it. The available replacement trunnions will either be too large or too small for the bars that you have now. What you will need to do is replace the head and the bars. When you do that though it is almost the same cost as a whole new system. So what I recommend is a system rated the same as what you have now but will cost a little less than a whole new...

  • If Tongue Weight is at the Spring Bar Max Capacity Does a Weight Distribution System Still Work
    If your tongue rating is right at 1,200 lbs you estimate then I would recommend going to a 1,500 lb spring bar like the Replacement Trunnion Spring Bar # RP58369 since you are probably over your 1,200 lb rating in actuality. A weight distribution system over its capacity will not be effective at all. If you are right at your capacity it's probably a good time to upgrade. I would recommend you determine your tongue weight. Check out the FAQ article I attached that details how to do this.

    If you were to use the head from the Replacement Head and Shank # RP54980, (the head only is listed as part # RP58167) with the Reese Titan Weight Dist Shank # RP54977 then the max rise with it in the down position is 4-1/4" while the max rise with it in the upward position is 8-1/4".

  • Can Equalizer E2 Trunnion Weight Distribution Spring Bars Be Used on Reese Head Unit
    I can appreciate your interest in re-using your Equalizer trunnion bars with a different brand of weight distribution head but I cannot recommend doing this. It is unlikely that they will fit properly. But more important, this combination of components will never have been tested together, so their actual combined capacity will be unknown. Neither Equalizer nor Reese would advise to mix their components with those from any other manufacturer. In the event that such a set-up suffered a catastrophic...
