Video Transcript for Reese Accessories and Parts 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. .

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. 154692

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. 261741

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. 402393

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. 303946

Fits like a glove. Not really sure why the mounting bolts on the head were cranked to 200 ft lbs shipped. Made job harder with no draw bar for leverage. You'll need some really big 1 1/8" deep well sockets and 24" crank bar for this big boy needs 300 ft lbs torx. Best done when head is attached to draw bar and draw bar is connected to Vehicle. The Ball mount you'll need 2 - 2" wrench's with 3ft pipe to torx ball at 600ft lbs. 43212

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. 23329

I received my order the day after placing it. I have replaced the hitch head and everything fit perfectly. Etrailer double checked the part that I requested to make sure it was exactly what I needed. This is the second time that I have used etrailer and it will not be the last. They are at the top of my list for hard to find parts, price, and service. 42685

I needed to replace my current WD head as I actually pushed one of the bars right out of the head when I took a dip in the road. It is the same as what I had before and I am making some changes to the setup so it doesn't happen again. 10827

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. 224189

You can count on Reese trailer equipment for what ever you haul. This is a replacement for my hitch which was stolen, and it also was a Reese so it seems to be the preferred hitch. 330776
