Video Transcript for Detailed Breakdown of the Replacement Weight Distribution Bolt-Together Round Bar Head

Today were going to be taking a look at the Pro Series replacement weight distribution head assembly. This replacement head fits Pro Series weight distribution systems PS49903, PS49902, and PS49901. Its made from a very durable steel construction with protective finishing, thats going to keep it safe from rust and corrosion. Under the ball platform, located right here, youre going to notice that it does come with a new set bolt. The area where the spring bars go up into, its going to have that spring clip design, makes installing and releasing quick and easy. I also want to point out that located right here on each side is going to be the included and pre-installed grease zerks. That makes maintenance seem quick and easy.

It does come with a 2 5/16-inch steel chrome-plated hitch ball. Its also going to include a sway control ball and necessary mountain hardware. The sway control ball can be used on either side of the head assembly. Its a really nice, durable construction, and then youll notice all the hardware that it comes with. I just want to go over all the components real quick. Its going to come with two new bolts.

This is for attaching the head assembly to the adjustable shank. The adjustable shank is not included, but it does come with the bolts, the nuts and the washers to get that installed and attached to the weight distribution shank. Its also going to come with a hitch pin and clip. This is to secure the weight distribution shank inside the receiver tip of your hitch. Its going to come with two other clips. These are for the frame brackets or lift brackets.

Those clips are used to secure the lift brackets in the up or engaged positions. Then, its going to come with a new spacer rivet. That allows you to get the proper tilt that you need. Theres a slot right here for that spacer rivet. Then, its going to come with seven washers, so you simply add or remove washers to get the tilt that you need for your application. Thats going to do it for todays look at the Pro Series replacement weight distribution head assembly..

The product met expectations. I was dissapointed to learn that the Round Bar Head we purchased was not designed to work with the Shank (RP54970) we also purchased. (although with some modification we can make it work and avoid return/re-ship shipping costs.) Something was missing from the information we researched in trying to decide what combination of products to buy.

CUSTOMER SERVICE WAS VERY HELPFUL.

I contacted the manufacturer and the replacement weight distribution head you need is part # RP58112 for your reese round bars with 1,000 lb tw. According the manufacturer they changed the tongue weight on the 10,000 lb round bars to 800 lbs tongue weight 10 years ago but they still use the same head.

Great service, great shipping

I am very pleased with this replacement head for my hitch. It came with a complete hardware package and it was easy to install.

This is a good head. I use a little grease on pivot points and I keep it out of the weather when not in use. It looks like new.



by:

Great price, fits and looks like my original. Just what I needed!



by:

Used this hitch a few times this summer and it works perfectly. Glad I got it. Suzanne at eTrailer is an excellent service rep and I really appreciate her help in getting me the right parts. I'll be back when I need these products.

This is a solid, well made RV trailer hitch. I have only one challenge with it and that is I cant pull back the flat springs that hold the pin for the leveling bars with my fingers. I have to use a flat head screw driver to release them. I keep an old screw driver in the camper just for that.



by:

Well it's been a year since I purchased this product and it was worth every penny. I was looking for a comparable setup for my new RV as to what I was using on my truck. I wanted to reuse the weight distribution bars between the two hitches. The hitch on the truck was a much older version of a simular style hitch. The guys etrailer were great in analyzing my needs and recomending a new hitch for my RV that would fit my bill. And it did perfectly. Great guys to work with a great product.

The product:
The Pro Series Replacement
Weight Distribution Bolt-Together Round Bar Head (Item # PS58442) I purchased from etrailer.com is perfect! I was not aware that it came with the trailer and anti-sway bar hitch balls, which saved me a lot of time by not having to swap over my old ones. This unit also comes with grease fittings for the tension bars, which my old unit did not. My old one wore out most likely because there were no grease fittings. The unit comes with all new bolts and spacer, so you don't need anything at all from the old hitch head to install this one. The installation time was under 15 minutes.

The Company (etrailer.com):
My experience with etrailer.com was "unusual"...that is, unusually GREAT! In a world of automated answering systems and companies that virtually eliminate human communication with customers, etrailer.com is a breath of fresh air! My inquiry about this replacement part was by email, with pictures of my old part for clarification. I did not have a manufacturer name or other markings on my old hitch head. I received a prompt reply from this company with additional questions. When they got all the information, they found a unit that would fit and let me know via email. I ordered the part, which was a special order. The folks at etrailer.com sent me an initial email to let me know to expect a delay, but they didn't stop there. I received additional communications from them as to the progress of my order, and then an email indicating it was shipped. The shipment for this heavy part was FREE because it was over $100.

If other companies would continue to communicate with their customers on a more personal level, the world would be a better place. Thanks etrailer.com!



by:

Arrived quickly and worked as advertised! All hardware included. I have a 2017 suburban so we needed a drop hitch because it has air bags in the back, this was perfect. The only thing missing in my opinion is a little direction on how to set things up, being a relatively new trailer owner I had to do a little googling and find out exactly what a “spacer rivet” was and how to adjust the ball to find the correct ride. Other than that this product is great



by:

This product was as advertised. It was completly assembled and works great! The etrailer experiance was awesome! All the local RV shops and trailer shops wanted double the price for this hitch head or would only sell me a whole assembly for $399.00 I had my hitch stolen 2 days before a vacation and etrailer took the extra care to get my hitch shipped to me and on time! Thanks etrailer!



by:

This is the only part I needed for a used trailer I bought as I had all the other components. It fit perfectly and is very well made. I am very grateful that E-trailer had this part and as always had the best price out there. Shipping was just as all the folks at E-trailer said...prompt and on time. I will be buying again from all the good folks at E-trailer! Thanks again!!!



by:

I was happy you had the hitch part available that l needed and didn't have to buy receiver with equalizer and sway control. My hitch was stolen but didn't take the equalizer bars and sway control.



by:

Exactly as ordered and needed. Just have to double check the bolts for tightness, can't be too safe when hauling a trailer.

I needed an extra head piece for my motorhome and didn't want to buy a whole hitch assembly for just the head piece so this worked out great! Fast service great prices and free shipping, what more could you ask for! Dave



by:

Fast shipping and love being able to track the package with ease. Packaging of the item could be better. Found my hitch protruding through the side. No damage but it could be prevented. Will definitely be a return customer.



by:

Thanks for staying on top of the tracking number of my order. It arrived on time and in perfact shape. Erica thank you. You did an outstanding job serving your customer. I will ask for you when I purchase one of your products in the future.



by:

Received product sooner than expected. Box was torn on bottom and hardware bag wasn't sealed. Hardware parts were mostly out of bag. Missing one washer. I haven't assembled or used hitch yet. We already have two different sway bars that we hope will fit. If not, will take a next step.



by:

Great customer service, I had an issue and it was resolved to my satisfaction. It was not the fault of etrailer, but of one of their manufactures. I like the way they stood behind the product.



by:

Fit my setup perfectly and it came all assembled. Attached it to my second hitch shank and I was ready to go.

Thnxs etrailer!!!



by:

Ordered this replacement head, everything was just as pictured, all I have to do is put it on my truck. I got the 1 component I needed and all the hardware necessary and at a great price. Delivery was just as promised.

I will order from them again.

My husband said it is perfect. Fast shipping and wonderful communication. Thanks so much.

  • Recommended Friction Sway Control System For Dual Friction Setup
    For the dual friction you are looking for, I recommend adding the Reese Friction Sway Control Kit - Economy - by Draw-Tite, Reese and Hidden Hitch # 83660 to your hitch ball. This adjustable friction sway bar can be added using the Reese Sway-Control Bracket for 2" Ball Mounts - Class III and IV # RP26003 or the 1-1/4 inch ball mount bracket # RP26005. It is recommended to pull the cotter pin to disengage this bar when backing up. You can also expand this system by adding another bar...

  • Replacement Head for Weight Distribution System
    There are many replacement heads available. I've attached a couple links to assist you with the options we currently have available. One is for square bars, one for round bars, and one for trunnion bars. If you can't narrow it down based on look, send me a picture with as many markings as you can and I'll see what I can do to help. There aren't bushings on most weight distribution systems, so I need more clarity to help.

  • Replacement Head for Reese and Pro Series Round Bar Weight Distribution Systems
    The Reese round bar weight distribution systems and Pro Series round bar systems are fundamentally different and the parts are not interchangeable. For a Reese round bar system use head # RP58112. For a Pro Series round bar system use head # PS58442.

    Hey Greg, thanks for providing all that info it really makes everything much easier! So I did a little digging around, and it does look like yes the Replacement Chain Hangers for Reese Pro Round Bar Weight Distribution System # RP24KR will work great. The head used # PS58442 is the same head for both systems. How did you like the old system? I've heard good things but I haven't personally used one yet.

  • Recommendation for Adding 2nd Friction Sway Control Bar to Trailer
    To add a second friction sway control, you will need the second Reese Friction Sway Control Kit # 83660 and you'll need to weld a tab onto your trailer hitch ball platform like # C45822. The friction bar will simply be inverted on the left side, but that will not impact the function and is designed for use on either side. I've attached an article to assist and 2 bars are recommended on trailers over 26 feet long or if you simply want more sway control. The other option is to use a weight...

  • What If A Trailer's Tongue Weight Exceeds Capacity of Weight Distribution System
    If the actual tongue weight of your trailer exceeds the 600 pound capacity of your weight distribution system then it essentially will be as if you don't have a system hooked up at all. The spring bars won't have the strength to properly distribute weight and also won't be much help in fighting sway on the highway. It's also important to note that any added cargo weight you have behind the rear axle of your tow vehicle counts towards your total tongue weight as well so it's likely that...

  • Replacement Head for Pro Series 10K Weight Distribution System
    It looks like you've got an obsolete Pro Series 10k Weight Distribution System. The Replacement Weight Distribution Bolt-Together Round Bar Head part # PS58442 is the correct replacement. However, it appears you're also missing a weight distribution shank, like # 63911, and possibly some other smaller components. For that reason, I recommend simply purchasing a complete system, like the Curt # 17302 which will include everything you need (except a hitch ball) at a super economical price. If...

  • What Would Happen if Higher Rated Weight Distribution System Was Used than Needed
    If you use a weight distribution system that's rated too high for the tongue weight of the setup you'll end up with a really rough ride quality. Best option is a weight distribution setup that has a tongue weight range that allows your loaded tongue weight to fall right into the middle of. Since you referenced a Pro Series weight distribution component the correct rated Pro Series system would be the part # PS49583 which has a tongue weight range of 700-1,000 lbs. You should note that...

  • Determining if Weight Distribution System is Being Overloaded
    I'm a bit confused by the description of your set up. You mention that the Eaz-Lift set up is rated at 14000 towing/1400 tongue weight, but then go on to say the bars are rated at 600 lbs. If your spring bars are rated at a maximum of 600 lbs, it means that the tongue weight of the trailer plus the weight of anything stowed behind the rear axle of the tow vehicle cannot exceed the rating of the spring bars. It's vitally important that you're aware of the total tongue weight of your set-up....

  • Will Reese Round Spring Bars Fit a Pro Series Weight Distribution Head
    Only the RB2 head, # 58333, is the same between certain Reese systems and Pro Series systems so head # PS58442 will not work with the Reese round spring bars. If you can tell me the part number of the Reese system you have I can look up which head fits it.

  • Replacement Pro Series Weight Distribution Head for Round Bar System

  • Weight Distribution Hitch Recommendation for my 420-590 Tongue Weight Camper.
    We can get this figured out. Thanks for all of the information provided. It goes a long way in being able to determine exactly what you need. One thing to keep in mind is that the weight of the system is actually not added into the equation. It has a self balancing design and when set up has no weight added to the equation. That means you are going to be between 420-590 in tongue weight regardless of the configuration you choose for that trip. With that in mind the Fastway e2 Weight Distribution...

Due to the price of the individual parts you need (head, ball and shank) it is most likely going to be a better option to replace the entire system. We only have the one replacement Husky head # HT31516 and when you combine it's price with a new shank like # RP3215 you are at the price of some systems.

So, for your Haulmaster WDS, you're going to need to stick with Haulmaster when it comes to replacement parts, or you can upgrade your entire system.

  • Recommended Weight Distribution Sway Control for 2013 Lincoln Navigator and 33 Foot Travel Trailer
    If you already have a sway bar installed, you have some help, but not enough. The friction sway bars are for trailers under 26 feet long, so you would need to add a second one for a trailer of your length. This will require a bracket like # 3442 to be welded on to secure the 2nd friction bar to a ball mount or a weight distribution head with two options like # PS58442 to mount a second bar like # 83660. For the best sway control option, I recommend upgrading your system to a weight distribution...
