Video Transcript for Pro Series Weight Distribution PS58442 Review

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..

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! 123386

I contacted the manufacturer and the replacement weight distribution head you need is part # RP58112
Replacement Head for Reese Weight Distribution System - Round Bar
$189.26
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.

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! 430142

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. 482480

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. 315456


Comments

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.

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!!! 172460

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. 132081

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. 46310

Ask the Experts about this Pro Series Accessories and Parts

Do you have a question about this Accessories and Part?


  • Recommendation for Adding 2nd Friction Sway Control Bar to Trailer
  • To add a second friction sway control, you will need the second Pro Series 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...

  • Are Weight Distribution Head Assemblies and Shanks from Different Brands Interchangeable
  • Most weight distribution shanks share common hole size and spacing dimensions (3/4-inch diameter spaced apart 1-1/4-inch on center) so you can use the head assembly from one brand, such as Pro Series # PS58442 on Curt shank # 17120. All 2-inch replacement shanks for WD systems are linked for you. Other parts from WD systems are typically not interchangeable.

  • Recommended Friction Sway Control System For Dual Friction Setup
  • For the dual friction you are looking for, I recommend adding the Pro Series 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...

  • Replacement Head for Older Draw-Tite Round Bar Weight Distribution System
  • I spoke with my contact at Horizon Global (parent company of Draw-Tite) regarding your older Draw-Tite Weight Distribution System. He stated that your particular system is comparable to the current Pro-Series (also owned by Horizon Global) Round WD System # PS49903. For a replacement head that will be compatible with your existing system, you can use the Replacement Weight Distribution Bolt-Together Round Bar Head # PS58442. This includes the 2-5/16 inch chrome hitch ball, sway control...

  • Is the Weigh Safe Hitch Ball # WSUN-3 Compatible With Pro Series WD Head # PS58442
  • I went out to the warehouse and compared the Replacement Weight Distribution Bolt-Together Round Bar Head # PS58442 and the Weigh Safe 2-5/16" Hitch Ball w/ Built-In Scale # WSUN-3 that you referenced and it looked like there would be just enough room for the scale to fit on the bottom part of the head. My main concern is whether or not the bars for the Pro Series Weight Distribution (WD) system are going to crush the scale when you are making turns. I attached a picture that a customer...

One is parts is the dual cam arm of the Strait-Line Weight Distribution System w Sway Control - Round Bar # RP66087 and the other is a Draw-Tite Pro Series # PS58442. I recommend the Replacement Head for Reese Weight Distribution System - Round Bar # RP58112, along with the Replacement Round Spring Bar for Reese Weight Distribution System - 800 lbs TW # RP58114 if your bars are not these as the straight line system will suite you...

  • How to Loosen Over-Tightened Fasteners on Pro Series Weight Distribution System # PS49903
  • Thank you for providing a photo of your Pro Series weight distribution hitch # PS49903. The assembly/installation instructions for this kit are linked for you for reference and they indicate the correct torque specs for the included hardware. It is very important that the instructions be followed precisely since the hitch's specs may not be met if it is not installed as intended. Proper torque settings are possible only when you use a torque wrench. A monkey wrench and cheater bar will...

  • Replacement Head for Husky Weight Distribution System
  • While some components of a weight distribution system can typically be interchangeable between manufacturers, such as the adjustable shank, replacing the system's head with one of a different brand is not recommended. This is because the head is tested along with its spring bars, and changing out these parts can affect the system's overall rating and performance. Because of this, I do not recommend using the Replacement Pro Series Weight Distribution Head # PS58442 on your Husky system,...

  • 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...

  • Installation Instructions and Video for the Pro Series Weight Distribution Head part # PS58442
  • There aren't printed instructions, but there is a diagram that I attached that shows how all the pieces install together. For further setup info check out the installation instructions I attached for the Weight Distribution system part # PS49903 and the install video that details how to install and setup this system. The WD head part # PS58442 that you referenced is the head of assembly of the part # PS49903.

  • Longer Shank Recommendation For Using Pro Series Weight Distribution System With Taller Vehicle
  • The # PS49901 that you have is compatible with virtually all of the weight distribution shanks that are available since most are made to industry standards. The Curt Shank part # C17124 is most likely going to be your best option. From the top of the shank down to the center of the lowest hole measures 13-1/2 inches.

  • Is Pro Series Weight Distribution Head Compatible With Fastway E2 System?
  • You would not be able to use the Pro Series Replacement Weight Distribution Head # PS58442 with a Fastway E2 system; you would need to replace the head unit with either: - Replacement Head for Fastway e2 Weight Distribution Systems with Round Bar # FA94-02-1055 (which works with all Fastway round bar systems) - Replacement Head for Fastway e2 Weight Distribution Systems with Trunnion Bar # FA92-02-1255 (which works with 6,000 lb, 8,000 lb, 10,000 lb, or 12,000 lb trunnion bar systems)

  • What Parts Come with the Pro Series Replacement Weight Distribution Head # PS58442
  • The replacement Pro Series weight distribution head # PS58442 does come with the hitch ball, sway control ball, and all necessary mounting hardware.Basically everything you see in the pictures. This head is a replacement for Pro Series weight distribution systems # PS49903, # PS49902, and # PS49901.

  • Recommended Weight Distribution Head Assembly Replacement
  • Thanks for providing a picture and the head assembly is certainly bent as you referenced. The Pro Series bolt-together round bar head # PS58442 you referenced will fit your shank, but probably wont fit your Husky spring bar system because they aren't interchangeable. Since you are wanting a system with a 12,000 pound tow rating, I recommend going with an entirely new weight distribution setup. With that said, I recommend the Reese Steadi-Flex with sway control trunnion system # RP66560....

  • Replacement Weight Distribution System Recommendation for Stolen Husky WD Components
  • Sorry to hear about your weight distribution system getting stolen. 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. Actually a Pro Series Round Bar system like part # PS49583 would cost almost as much as just one of the above mentioned...

  • Replace Head Assembly 2 inch Hitch Ball and Sway Control Plate for Pro Series Weight Distribution
  • The replacement head assembly for the # PS49902 that you referenced is the part # PS58442. This comes with a 2-5/16 inch ball that you would need to replace with a hitch ball with a 2 inch diameter and a 1-1/4 inch diameter shank like part # A-90. For a replacement sway control mounting plate you would want the part # RP58062.

  • Does Pro Series Weight Distribution Head Fit Draw-Tite Weight Distribution Hitch?
  • The Replacement Weight Distribution Bolt-Together Round Bar Head # PS58442 will potentially fit your Draw-Tite weight distribution system. This head fits Pro Series weight distribution systems # PS49903, # PS49902, and # PS49901 that are round bar systems comparable to Draw-Tite systems as they have the same parent company. If you let me know the exact part number of your system I can attempt to verify a fit for you.

  • 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.

  • Pro Series Weight Distribution System # PS49901 Recommendation to Replace Missing WD Components
  • Yes, the Pro Series Weight Distribution System # PS49901 would work with the spring hangers you currently have attached to the frame on your trailer and would basically provide you with a brand new WD system for about the same price as replacing the components needed.

  • Replacement Spring Bars and Head for Old Reese Round Bar Strait-Line Weight Distribution System
  • Given the wear you mentioned on your bars and the distortion you mention, I'd highly recommend replacing the spring bars as well as the weight distribution head. The bars are under a tremendous amount of strain, and when they're worn, their weight bearing capabilities could be negatively affected. Reese no longer makes a 1000 lb capacity round bar. You'll want to go with either the # RP58115 1200 lb bar or the # RP58114 for 800 lb bars, depending on your fully loaded and ready to tow...

  • 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.

  • Maximum Gross Trailer Weight of Pro Series Weight Distribution Head Used as a Ball Mount
  • The weight distribution head # PS58442 is a direct replacement for # PS49901, # PS49902, and # PS49903. All three have a gross trailer weight of 10,000 pounds. I verified with Pro Series that the head can be used without the spring bars as a ball mount but its maximum capacity is 10,000 pounds.

  • Will Pro Series Replacement Weight Distribution Bolt-Together Round Bar Head Fit Reese Shank
  • The Reese Weight Dist Shank, part # RP54970 has 1-1/4 inches spacing between the holes and will work great with the Replacement Weight Distribution Bolt-Together Round Bar Head, part # PS58442. I verified this with my contact at Reese.

  • Replacement Pro Series Weight Distribution Head for Round Bar System
  • Unfortunately the kit they made to replace those has been discontinued and they have no stock of the old parts. You will need to purchase a new head # PS58442 to have a functional part because the clip will no longer hold that bar in place.
