Video Transcript for Reese Weight Distribution RP58167 Review

Today we'll be reviewing part number RP58167, this the Reese replacement head for Reese weight distribution systems with trunnion bars. It's going to feature the forged raised ball platform here at this portion. That's going to eliminate the need for a raised hitch ball. You're going to get all the mounting hardware and the serrated washers. The serrated washers are great to have because they actually allow the head to pivot without having to add any additional spacers or washers to the unit. You're going to get the two large bolts, you're going to get the two serrated spacers, you're going to get the spacer here in the middle and you're going to get the lock washers and the nuts.

It is completely set up and ready to be put right on to a shank that is made for weight distribution. Well take a measurement of the ball hole diameter, it's going to give us a measurement of an inch and a quarter so this is designed for hitch balls with an inch and a quarter shank in diameter. It's made from a solid steel construction with a 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 today's review of part number RP58167. This is the replacement head for Reese weight distribution system with trunnion bars. .

Replacement Head for Reese Weight Distribution System - Trunnion Bar - RP58167

Average Customer Rating:  4.9 out of 5 stars   (111 Customer Reviews)

Adjustable head assembly works with Reese trunnion-bar weight-distribution systems. Mounting hardware included.


One of the best out there for adjustability, strength, and ease of set up.
I use mine with a friction anti-sway bar. After 24 years of Wisconsin corrosion, it was time to replace it, as the very good corrosion coating was finally vanquished.


etraler is the best ,the best customer service in the industry this from areal customer,if you don’t believe me look at their tutorials. Order something from them and see and I’ll bet you’ll be happy with them.


First of all the product was perfect. I made a mistake and ordered the wrong one and Troy was amazing. Since I was busy he worked with my wife to get my mess worked out and helped us a ton. etrailer is a great company and I will be working with them for all my trailer needs in the future. Thank you Troy and staff at etrailer!!


Was a perfect match to the one we had. Customer service was great with helping me find exact match. Worked great on last rip we we went on. Thank you.


Reese replacement head looks good, won't be able to install because of the weather here in Michigan. Replacement for Reese Head that is showing wear after a couple years of use, would rather replace the part than have it fail while traveling.


It is good to be able to replace only the parts that are worn without having to buy the entire new system.
Good idea to keep the trunnions greased but also to clean it up once in a while and check the wear.


We liked the results of how well the Reese weight distribution and sway control system so much that we went ahead and ordered the parts needed to set up a second vehicle to tow the same trailer. Reese and have made preparing for and towing the race car hauler a breeze! We couldn't ask for a better combination...

The initial review matches how we feel about it now... We couldnt ask for a better combination!

Finally got around to installing new hitch equipment. The new shank and Reese head worked out to be a fine combination for my 2018 Ram 2500. The longer shank was what I needed for my camper. Great parts and a great price and fast delivery. thanks a lot. Mike B. Northwood Ohio

Excellent! Just about ready to start using the camper again this year. The hitch equipment I bought will be put to good use again. I am well satisfied with the quality and the price I paid. Thanks again.

Quick response the correct part no hass les


Used this hitch all last summer. Works as advertised. Good quality. Has slightly different openings on the underside of the top that the bars angle in to (they go in at a different angle than may old hitch), but it works the same, tomato, tamato! I would definitly recomend this product.

After a year the hitch is working out great!

Correct part, easy ordering and fast shipping. Came with all new hardware and instructions for hitch setup. I would give it a five star review, but it didn't come with a shim which I thought would be part of the hardware. Had to find that separately.


This was the replacement for the ball mount for the Reese Weight Distribution System I purchased about five years ago. The original ball mount had excessive wear (probably because I didn't know it needed to be lubricated each day while it was being used). This ball mount is exactly the same as the original. I also ordered the replacement bolts and washers (58207) because I didn't understand that the replacement ball mount included all new washers and bolts so these were not needed. etrailer has sent me a return authorization for the bolt and washer kit.


This was not my first etrailer purchase nor will it be my last. I needed to replace the hitch head of my Reese Straight-line Trunnion hitch (ofvwhich im a huge fan) after 15+ years of use. etrailer ‘s information and price couldn’t be beat. Throw in quick service and free shipping and it was a no-brainer. They are one of the best companies I’ve ever dealt with.


Great job on all the videos and Q&A posts! Thank you. They gave a good understanding of what I needed and why.
The only issue I have with this head is the tight quarters to tighten the nut for the
1 1/4 shank hole. The nut is a 1 7/8 which is not a common wrench or socket a person has around. Even with the included spacer and a 1" shank ball, the nut is still 1 7/16. A socket, I think, is required as the space in the head is tight. I took the head to a local semi garage and they had the socket to torque the hitch ball nut. Other than that, it is a good solid unit.


Good quality part, very sturdy construction and all seems to work very well. My only word of advice is there is a good possibility that the very first time you go to insert the trunnion bars to the head, they will be VERY tight and you'll have to use much more force than normal. My only guess is the powder coating took up some of the small tolerance there and you have to get that to wear just a tad first because now after inserting/removing several times everything works nice and easy. Everything else worked really well and seems like a quality piece. My only other note would be that you won't be able to fit an adjustable wrench on the ball nut to tighten down the ball with how the head is designed, you'll either need a socket or a box wrench , or at least that was my case with using a 2-5/16" ball with a 1-1/4" shank.

Fast ship fit perfect


This W/D head has performed perfectly over the past year. At first, I had mistakenly ordered the wrong head. With the help of etrailers technical support representatives, we chose this model to meet my needs. I have never second guessed that decision. I have complete confidence when towing with this.


This is a replacement for a hitch head that was broken. It fits perfectly! Delivery was phenomenal!

Still great!!

There was a change in the design of the head - they increased the height of the ball mount area (thicker 1/4" or so). This cause a change in all of the geometry of the Wt. Dist. System, so a complete realignment of the trailer to the truck was required. This turn out to be a good thing! I was at limits on some of my adjustment before and this brought everything to mid range. The towing ride was really improved after the realignment. This is a great improved product.


Stout hitch or certain, replacing a broken Valley unit. This one looks exponentially stronger, and adjustment is much easier. Using this hitch with Reese 1500 lb bars and reinforced lift brackets.


WOW! The service from etrailer is something I have never seen before, that is a good thing. I ordered the hitch on a Monday evening and had it Wednesday afternoon! That was with the free shipping. The product is exactly what was described. I had numerous e-mails telling me what was happening with my order, very good. I will be ordering all of my hitch and trailer supplies from etrailer.


Worked as it should. I got it to replace the older style head that the little latches were all bent up. This head does not have those latches and it works better.


The head we had on our hitch had a stress fracture that we did not see. We trailered our camper 200 miles and that stress gave way as we drove into the driveway. It's a holiday weekend and we are stranded. After many online searches and phone calls we found the part on We had it shipped next day and it arrived in plenty of time for us to make it home that same day. We were worried about it being the right part since they are basically out of date. But it was and the camper towed better than before.


Replaced my 10 year old one that had a ear piece broke off.
