Etrailer was on point. Had the part and it was picked and shipped on a Sunday asap. The tracking information from the usps wasn't updated till the day of delivery which had me sweating, but Etrailer was awesome!


We have had great experience with eTrailer, These parts came in as described.


Exactly what I ordered.


Great quality


Perfect fit, help articles gave me enough information to replace entire suspension system on my toyhauler with no previous expirience. Quick shipping, i will be repeat customer


Right parts, good price, fast shipping.


Great job!


Great service, free shipping, received product within 2 days of order. Also ordered the Lippert Never Fail Suspension Upgrade Kit with this equalizer. Looking forward to suspension bushings that don't wear out every couple of years.

Mike G.


The new TruRyde equalizers were an exact match to the old ones. I replaced the bushings that came in them with the Lippert Never Fail bushings before installing them. A year and 4,900 miles later, the new equalizers and Lippert bushings totally corrected my tire wear issues.


While we haven't travelled with our 5th wheel yet since installation of our new springs and and the Lippert Never Fail Suspension Upgrade Kit, I am very pleased so far. All of the parts arrived in less than 24 hours from the time I placed my order and etrailer representative was very knowledgeable and helpful. Everything looks great.


Nice solid product. I set mine up on 29 & 1/2 centers using 25 1/4 inch springs and 2.5 inch hangers and these came up a little short, shackle straps were about at 40 to 45 degrees rather than the reccomended 10 to 20 degrees. Rather than break the tack welds and move the outside hangers in a little closer I ordered a slightly longer equalizer that is also galvanized. I would recommend the hanger centers be 28.5 to 29 inches w/ this equalizer. Tack weld first and check set-up before finish welding!


Fit perfect, good quality and received in a timely manner.


Excellent as always Thank You


My old bushings were worn completely out. My equalizers were worn completely out. My trailer tires were rubbing the inside of my fiberglass finders. Trailer appears to be lifted 3/4 of an inch. Tires no longer rubbing finders and all of my trailer bushings can now be greased for longer life.

Great product and easy to install.


Looks good, work perfectly


I installed new springs and didn't get the fender clearance I expected. Ordered and installed these curved equalizers and gained another 1 1/2" of clearance.


Equalizer was exact replacement for my trailer. I will buy from etrailer again and recommend them to others. Also great shipping time also.



Ordered parts for my flatbed trailer on a Sunday and received all items the following Friday. Website was user friendly and parts were easy to find and order.

All items came intact and exactly what I ordered! Loved the free shipping as well!

Awesome job etrailer!!!


Works great


Good quality


Perfect fit. Made my trailer constructed from a one-time use house trailer axles to something a little more stable and sturdy.


Parts were perfect! My trailer brakes and suspension are like brand new again. etrailer is definitely the right place for all my trailer needs.


Perfect replacement part

Mike S.


I was very happy with everything I bought and the free shipping made all the difference. When I need trailer parts, Ill definitely be ordering from your company again. Thanks, Mike


I was very happy to buy this part it was easy to buy and the price was right and it came to the house in record time


Great product. Very quick service/delivery. Exactly what I ordered and needed to replace the worn parts on my trailer. Thanks.


These people at etrailer are very professional great job

  • Replacement Equalizers and Shackle Straps for 2007 Keystone Raptor 3712
    Thank you for all of that excellent information and photos! To replace the front equalizer you need the Curved Equalizer # TREQ104 and then for the rear equalizer you need the Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ105. To replace your 2-3/4" long shackle straps use part # TRSL275. While you're replacing everything it would be work swapping out your bolts as well. To do this you need a 9/16" diameter bolt that's 3" long like the Redline # 126B2. If you're looking to do an...

  • Upgraded Equalizers and SumoSprings for 2023 Grand Design Momentum 23G
    Since the parts are different for your 2023 Grand Design Momentum 23G we will go a slightly different route. You currently have a standard # TREQ104 equalizer on the trailer. That means the best fit is going to be the Dexter E-Z Flex Suspension Kit # K71-652-00. This includes the upgraded shackles, wet bolts, and bushing so there is no need to purchase them separately. I have this kit on my Jayco which you can see in the installation video below. For the SumoSprings you will need the #...

  • Replacement Suspension Components For a 1998 Fleetwood Terry Camper With Tandem 2-3/8" Axles
    First we do have the basic Curved Equalizer # TREQ104 which matches your 5-3/4" length and 2" height. As these are sold individually you will need 2 for your 1998 Fleetwood Terry camper. You might consider upgrading to a cushioned equalizer like the MORryde # MR87ZR if you want your camper to have a smoother ride with less vibration and shock transferred into the camper. For either kit we have the Wet Bolt Kit # MR76ZR which are also 3-1/8" on center like your current shackle straps. This...

  • Suspension Upgrade Kit With 3-1/8 Inch Shackle Straps For Tandem Axle Trailer
    There is not an option for the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers # K71-359-00 with 2-1/4" shackles so you'd have to get equalizers and shackles separately. And the 7/16" nuts are not a typo, that is the size of the bolts at the threaded ends. For the same length equalizer and suspension upgrade kit here's what you need: - MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR - Curved Equalizer for 1-3/4" Wide Double-Eye Springs...

  • Equalizer Upgrade For 5-3/4 Inch Long Equalizers on Travel Trailer
    Based on your description of a 5-3/4 inch long equalizer that is very short, it is highly likely you have the Curved Equalizer # TREQ104. This is the same length, and measures 2 inches tall from bottom bolt hole to center bolt hole. The Road Armor are too tall to replace these, but we do have an option for an equalizer upgrade designed specifically to replace these equalizers: - Dexter E-Z Flex Suspension Kit # K71-652-00 The E-Z Flex # K71-652-00 is for axles with a capacity up to 6,000...

  • Wet Bolt Kit & Equalizers to Replace 5-3/4 Long Equalizers
    The 2-1/4" shackle straps are too short so you'll want to get a similar length. There isn't a kit that includes both wet bolts and the equalizer you have but you can get them separately. You'd just need one wet bolt kit and two (2) of the equalizers for a full set: - Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 5-3/4" Long # TREQ104 - MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR

    First, I do appreciate the specific info, and we can get you the leaf springs, equalizer and bolts. For the leaf springs, since they flatten out over time, sand yours are 26-1/4 inch now, go with 26 inch springs. You didn't mention the weight capacity you need but we have a pair of options: - 2,000 lb Axle: 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # e77SR - 4,000 lb Axle: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - 26" Long # e22YR Then for the 13-104...

  • Availability Of Equalizer 5-3/4" Long And 1-3/4" Tall For Tandem Axle Trailer
    I do have a potential solution for you. While we do not have an equalizer that matches those measurements exactly, we do have the Curved Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ104. This measures 5-3/4" long and 2" tall. When replacing an equalizer we do want to keep every thing identical to stock if possible. There is going to be a small amount of tolerance. With the # TREQ104 we are looking at a difference of 1/4" each way, so it will undoubtedly be a suitable replacement.

  • Can E-Z Flex Equalizer be Removed and Original Equalizer Put Back On
    It sounds like you want to remove the equalizer portion of the Dexter E-Z Flex Suspension Kit # K71-652-00 and replace it with your old one, which sounds like it is the Equalizer for 1-3/4" Wide Double-Eye Springs # TREQ104. To do this you will want to replace what I assume are the existing nylon bushings in your equalizer and add two of the Bronze Bushings - Qty. 4 # K71-291-00. I have added some links to videos for you to check out as well.

  • Heavy Duty Suspension Kit for 3-1/4 Inch Shackle Straps
    Having a 1 inch difference in the length of the shackle straps would be a pretty drastic change to the amount of articulation you get out of your suspension, so going with that kit wouldn't be advisable. We don't have a kit that uses longer heavy duty shackles, so you'd need to assemble the parts separately. • You'd need two of part # K71-358-00 • Two # TREQ104 equalizers • Two of # TRFA73Z916DLNZ shoulder bolts with nuts This will provide you the same kit, but with longer shackle straps....

  • Equalizer Kit Recommendation for Trailer Suspension that is 5-3/4 inches Long
    For an equalizer kit that includes equalizers that are 5-3/4 inches long we have the part # AP233. This kit includes straps that are 1-1/4 inch though so you might be better off with the equalizers # TREQ104 and then the straps part # TRSL256. For wet shackle bolts you'd want the part # 126B2.

  • Which Trailer Suspension Equalizer Kit Fits Trailer with 31 inch Wheelbase

  • Replacement Upgraded Equalizer Kit for 13-104 Equalizer on Tandem Axle Trailer
    The correct replacement equalizer for your 13-104 is TruRyde Curved Equalizer # TREQ104. If you need the kit, you can use the Redline Tandem-Axle Trailer Equalizer Kit # AP233. The upgrade we offer for the 13-104 equalizer is the Dexter E-Z Flex Heavy Duty Rubber Suspension System - 5-5/8 Inch Equalizers # K71-652-00. These equalizers will replace the standard 13-104 equalizers and deliver smoother towing than standard equalizers. The rubber core will isolate and absorb damaging road...

  • Best Upgrade for EQ104 Trailer Equalizer
    Yes, the E-Z Flex Heavy Duty Rubber Suspension System part # K71-652-00 will be a direct upgrade for the EQ104 Equalizer. The part I really like about the E-Z Flex is that in addition to the cushioned equalizer upgrade which will help smooth out the ride you get much thicker shackle straps which will be more durable and it comes with wet bolts for easy maintenance. Therefore, it's more of a complete suspension upgrade in relation to other kits that simply replace the equalizer.

  • How Do You Measure The Height Of An Equalizer?
    The height of your equalizer is measured from the center of the horizontal mounting holes, to the center of the upper mounting hole as shown as the 2" measurement in the included diagram of the # TREQ104. If you can send me this measurement, and if you are wanting a standard or cushioned equalizer I would be happy to recommend the correct replacement for you. I included a video of the # TREQ104 for you to take a look at.

  • Using Taller Equalizer to Lift Trailer After Changing to Lower Mounting Holes on Hangers
    As you mentioned in your question, we typically recommend replacing existing hangers with taller ones to ensure you get the trailer lift you are wanting. But with that being said, in your particular application, that is what you will essentially be doing since you already adjusted the front and rear hangers to the lower mounting hole. Because of this, replacing the 2 inch tall Equalizer # TREQ104 with the 4 inch tall Equalizer # TREQ310 that you referenced will indeed lift your trailer...

  • Replacement Equalizers and Wet Bolt Kit For a Tandem Axle Utility Trailer
    Your tandem axle utility trailer will likely have an equalizer like the Curved Equalizer # TREQ104. These would have been held in place by 3" Shackle Bolts # 166081 and Nylon Bushings # 721590 and Shackle Links # LC122487 on the ends of the equalizer. The best upgrade you can do is to replace the equalizer and all mounting hardware with the Dexter E-Z Flex Suspension Kit # K71-652-00.

  • Would Too Long of Equalizer on Trailer Suspension Cause it to Be at Angle
    If your trailer is sitting perfectly level and the equalizer is sitting at an angle then yes I would agree you have too long of equalizers and would need to go with a shorter one like the part # TREQ104 which is 5-3/4 inches. Sometimes it's just a matter of the trailer not sitting level though.

  • Will The MORryde Equalizers Raise The Height Of My 2018 Keystone Outback 324CG Toy Hauler?
    The MORryde Shock Absorbing Suspension Equalizers # MR87ZR are approximately 1-1/8" taller than the Curved Equalizer # TREQ104 when measured from the top bolt hole center to the center line off the lower bolt holes. This would raise the trailer height approximately 9/16". Do remember the rubber cushion used on this Equalizer does allow for the equalizer to travel up and down so at times the height could be slightly more or less depending on the weight and any road shock traveling through...

  • Replacement for Rusted/Corroded Mor/Ryde LRE4100 Suspension System
    I do have an option for you but we do not carry any Mor/Ryde products so I would not have any replacement parts if that is what you are looking for. If there are components that are rusted or corroded then it would be best to just replace the entire system anyhow. The rubber cushioning has also likely worn down to the point where it is no longer effective. For replacement, I recommend the Dexter E-Z Flex Suspension Kit part # K71-652-00 for a 33" or part # K71-653-00 for a 35" axle spacing....

  • Can Road Armor Equalizers Replace Dexter 13-104 Equalizers
    Yes, you can replace your Dexter 13-104 equalizers - which are the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 5-3/4" Long # TREQ104 - with the Road Armor Shock Absorbing Equalizer Kit # LC696740. The Road Armor # LC696740 have a spacing of 6 inches between the bolt holes, which is similar enough to the 5-3/4 inch spacing of your current equalizers that they'll work.

  • Can I Replace TREQ104 Equalizers With TREQ356 And What Difference Will It Make?
    You can replace the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 5-3/4" Long - 9/16" Center Hole, # TREQ104, with the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 6-1/8" Long - 9/16" Center Hole, # TREQ356. Even though you can replace these parts, moving to a longer equalizer will cause one axle to have a disproportional amount of weight on it. The smooth transfer of the impact won't be distributed as effectively which will cause a rougher ride without as good traction....
