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

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

  • 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...

If your old bars were rated below 1,200 pounds and are over 3 years old, part # RP66009 will not work. If your old Trunnion Spring Bar was not curved, and is not the older style system with 600 or 800 pound spring bar it will work as a replacement, part # RP58358 will work. If you have the older style head with smaller Trunnion ends you will need the Draw-Tite...

  • Recommendation for a Weight Distribution Shank With a Long Drop for a Lifted Truck

The Curt Weight Distribution Shank, # 17120, is a 2 inch square shank and works with with Curt Heavy Duty Trunnion Style weight distribution systems. It has hole spacing of 1-1/4 inches, center to center. Reese shanks also have a hole spacing of 1-1/4 inches, center to center.

  • We have the instructions for you to review (see link). Remember to park the truck and trailer on a fairly level surface and get the ball mount height right, 3/4 to 1 inch higher than level coupler height, and you will not have any problems. The wrenches needed will be 1-1/8 inch, for the bolts attaching the weight distribution head, item # RP58167, to the shank. You may want to get some grease, item # L10337, to lubricate the spring bars and ball on your new system. I have attached...

  • Will New Spring Bars Fit a 15 Year Old Weight Distribution System
  • A 15 year old system is going to have a different head than systems made over the last few years. That means the bars have changed as well. You will need to also replace the head if you want to use 2 of bar # RP58357. For ahead use # RP58167. When you add up the cost you can almost get a whole new system, # 49586, which is what I would recommend. With it you are getting all new parts that you know are compatible. You may or may not need a different ball. If the ball you have now has...

  • 12,000 lb Replacement Trunnion Spring Bars # RP66009 Recommendation
  • Yes, you could use Replacement Trunnion Spring Bar, part # RP66009, as a replacement spring for your 8,000 lb system and you would have increased the weight carrying capacity up to 12,000 lbs. If you were to overload the your 8,000 lb spring bars your weight distribution system would no longer be effective at distributing the weight of your trailer. This could then cause damage to your hitch, vehicle frame, and weight distribution system. If you need a heavier spring bar you should...

If your head is numbered 58167 or it looks like # RP58167 then you will be able to use the spring bars. If your head uses the spring bars that are held in with clips that are dropped in the head, then the spring bars will not fit. If you find that they will work, you will need to order 2...

  • To upgrade to larger capacity spring bars on your weight distribution system, I would recommend to get the part number from the head of your weight distribution system or its approximate age. If it is 3-1/2 to 4 years old or older, you may need additional parts. If the head on your weight distribution is the Reese Replacement Head, part # RP58167, you will be able to use the Reese Trunnion Spring Bar, part # RP58358. The head will usually have a casting number of 112750 on it. This is...

  • Replacement Weight Distribution Spring Bars to Upgrade a 600 Pound System to a 1200 Pound System
  • I recommend going to 1200 pound bars because the 780 pound tongue weight is just a little too close to the 800 pound limit of the other bars. Plus you have to add the weight of any cargo carried behind the rear axle of the tow vehicle to the trailer tongue weight so that could push you over the 800 pound limit of the other bars. If you have head # RP58167 that you have referenced then you could use bar # RP66009 if you also have dual-cam sway control. If you have an SC system with friction...

  • The pieces that came off your weight distribution/sway control system could be several things, depending on which end the pieces came from and if they came from a sway control component or a weight distribution component. Either way, you do not want to tow your trailer with a naked bar until the problem is fixed. If it came from the spring bar and it is the end that goes into the weight distribution head, it is probably the trunnion, like # 58098. This is the part that holds the spring...

  • Are Trunnion Latch Pins Included with Reese Replacement Weight Distribution Head # RP58167
  • The Trunnion Latch Pins, # 58025 are not included with the # RP58167 Replacement Weight Distribution Head. According to our friends at Reese, this head is compatible with your older spring bars that use the latch pins, but they will not fit quite as tightly as they did in your old head, there will be additional slop or movement, which should not affect their function. The replacement head is indeed compatible with a shank intended for use in a 2-1/2 inch receiver, like the # RP54977...
