Perfect, matched the one I bought 6 years ago and lost on the highway! 693100

- 58346

Upgraded from the original 800 lb. spring bars to the 1200 lb. spring bars when I got a larger 24' enclosed trailer. They made a huge difference with increased tongue weight of the new trailer. Don't underestimate how much difference the correct WD set-up makes. 672010

Exactly what I ordered and fast shipping! I was already able to swap out my old 800lb bars for these in minutes. You guys are amazing, I will certainly buy again from you in the near future! 471909

I got great service when I called E Trailer. I needed parts to my load leveling system and the sales representative I spoke with was great. I received the exact parts I needed. Thanks. 141763

It's what i ordered, and what's in the picture. And the delivery was real fast. Good price, too. Where I was surprised is that it doesn't come with the ubolt and chain. Kinda tough when you lose one (really the only reason someone would buy a single) to move the chain over. Maybe a note on the part that buying a clamp/chain is required would be good. 23774

  • Replacement Trailer Bracket for Reese Sway Bars 22210
  • The Replacement Head for Reese Weight Distribution System - Trunnion Bar # RP58167 is confirmed to go with your sway bars. There are two possible sway bar styles and that will impact the brackets needed. If you have the tapered bars that are straight at the end like # 58346 then you can use the # RP6637 for chain use with Reese Replacement Chain Kit # 55630 but the SC system brackets are no longer available. If you have the bars with the curve like # RP66009 then you will use brackets...

  • Upgrading to 1,200 Pound Weight Distribution Spring Bars for 7,725 Pound Trailer
  • The dry hitch weight is the weight with the trailer empty of everything including propane and any other cargo, water, and other items. The gross weight of your 2017 Grey Wolf 26DBH is 7,725 pounds. That is the maximum the trailer can weigh when loaded and ready to tow. The empty weight is 5,795 pounds. So is 725 is the dry hitch weight then that is 12.5 percent of the gross trailer weight. That means that when loaded to the max 7,725 pounds the tongue weight would be around 965 pounds....

  • Solution for Reese SC Weight Distribution Trunnion Bar Needing Replacement
  • Thank you for all of the pictures. I do have a solution for you but when I reached out to my contact at Reese he said that you have the older SC weight distribution (WD) system and there aren't any replacement bars that will fit your application. The Pro Series trunnion bars, like part # 58346 you referenced, have a different attachment configuration which keeps them from being interchangeable with the Reese systems. For your setup you either need to replace the entire WD system or...

  • Matching Weight Distribution System to Existing Chain Hangers and Sway Ball on Older Trailer
  • If you can provide the manufacturer name and the part numbers of the weight distribution equipment you have, I might possibly be able to fill in the missing pieces. Any photos you could send would be helpful. The chain hanging brackets and sway ball could likely be re-used, but the trunnion bars cannot unless we can get a manufacturer and part number off of them. In all honesty, It's likely that you'll need to replace the system. Because W/D systems are frequently updated, if the system...

  • Curt Weight Distribution Trunnion Bar Compatibility with Head Assembly C17307
  • Weight distribution/sway control (WD/SC) spring bars can often be changed out for new bars with a different weight capacity but it is never a good idea to mix components from different systems or manufacturers. With the Curt trunnion style head assembly # C17307 you could use a spring bar like # 17305 for trailer tongue weight (TW) up to 800-lbs. Please feel free to let me know your trailer TW.

  • Replacement Lift Bar for Reese Weight Distribution System
  • When you say lift bar, I am unsure if you are asking for a the handle for lift brackets or if you are referring to the spring bars. For the handle for lift brackets, you will want # RP58162. This provides leverage to ease lifting a positioning of the snap-up chain brackets. If you need spring bars, there are 2 round bar options based on capacity: # 58337, # RP58114. For trunnion bars there are a few more options in 2 styles like # RP22225 or # 58346 and these also have different...

  • Are Replacement Weight Distribution Spring Bars Sold as a Pair or Individually
  • Our replacement spring bars for weight distribution systems, such as parts # RP66009 and # 58346, are sold individually. These and all other parts for such systems can be seen on the linked page.

  • Trunnion Bar for Curt Weight Distribution Head 17307 for 7000-lb Trailer
  • For a 7000-lb loaded trailer the typical tongue weight (TW) range will be 700 to 1050-bs so the trunnion bar you'll want to use with Curt weight distribution head # C17307 is part # C17303. You will need to order two since this bar is sold individually. If you want to measure your trailer TW accurately you can use the Sherline scale # 5780. Please tell me the total TW you measure and the weight of any cargo behind the rear axle of the tow vehicle, since that has to be added to the trailer...
