Dimensions of Equalizer

Absorbs Road Shock and Reduces Chucking

Upgrade your trailer's suspension for a smoother ride with these cushioned Equa-Flex equalizers. These units deliver a ride as smooth as you'd get with torsion axles, but at a fraction of the cost. The rubber cores effectively absorb vibrations and bumps and reduce the back-and-forth movement known as chucking. Unlike standard cast equalizers, the Equa-Flex's rubber cores soak up this energy like a sponge instead of transferring it to your trailer and cargo. The result is a more comfortable ride with less wear and tear on your trailer.


Easy Installation

Illustration of a tandem axle trailer suspension system

It's easy to upgrade your trailer's standard suspension with a set of cushioned Equa-Flex equalizers. You will need 10 standard suspension bolts and 8 shackle straps (each sold separately) to incorporate the equalizers into your trailer's suspension system. Two of the suspension bolts will be used to suspend the equalizers from the center hangers, and the other 8 bolts will be used with the shackle straps to attach the equalizers to the double-eye leaf springs. If you would like to replace the bolts that attach the springs to your front and rear hangers as well, you will need 4 additional suspension bolts (sold separately).

Ordering my parts from etrailer was a joy. They helped in every way they could. Received my parts on the day they said. Havent had time to put them on yet. Tickeld pink with etrailers service. Not the first time we have bought from them.



by:

This was a great upgrade. I installed myself, the only issue I had was getting them lined up with the leaf spring. However, I got it figured out and the opposite side went much faster. I think the trailer pulls much better and you don't get the bounce after hitting a bump, RR tracks etc.. Glad that I made this upgrade. If I had one negative, it would be the packaging, the powder coat on one was scratched through.



by:

First I must say what great customer service I received when I called to order the Equa-flex for my trailer. I talked to Rose in sales and she helped me pick the right suspension enhancements for my trailer. I installed the Equa-flex 5-6k and the Dexter heavy duty shackle kit on my 30' 2016 Forrest River Wildwood. The kit and the instructions were easy to read and understand. The kit is definitely an upgrade over the stock suspension, just look as t the pictures I provided. The trailer rides smooth and handles great. I will be installing the Equa-flex kit and shackle kik it on my Dads trailer this year. Thanks Etrailer for your great products and customer service.



by:

I needed to replace everything (suspension) on my 45 year old trailer. The equa-flex equalizers appeared to be an upgrade over standard type equalizers. It seems to tow better and smoother. Replaced leaf springs and all associated shackles with greasable shackle bolts. The MORyde shackle kit did not work for my application - the shackles were too long, went back standard length shackles for the correct angles on the equalizers. My trailer weighs around 6500 lbs., we’ll see how the equa-flex units hold up. Overall, I would recommend this product. etrailer was great to deal with.



by:

Great product. My camper came with these when I purchased it new in 2012. I had a leaf spring break on our last trip and decided to replace the equalizers while replacing the springs. They do a great job with absorbing shock from rough roads which improves handling and track of the camper. I recommend this product and I recommend etrailer.com. Prices and selection are good and the fast, free shipping is definitely a huge plus. Attached are photos of the installation which include pics of the old ones that I replaced.



by:

I was able to install these myself. Was super easy once I got my trailer jacked up! I replaced the equalizers and the leaf springs at the same time. We are getting ready to take it out next week! They performed great last year and I felt the trailer rode better with these on!



by:

I had a challenging situation regarding a replacement Axle Equalizer from year 2011 and between the Tech side and Parts, they were able to help me.



by:

The operator was very helpful getting me the correct Equalizers. They help the trailer ride much smoother.



by:

I received my Equa-flex cushioned equalizers along with the Never-Fail bushing kit both by Lippert. I did take delivery as projected by etrailer and have had them installed on my 5th wheel. So far, they are performing well and have given me peace of mind as we prepare to embark on a 10 - 15K trip to the west and northwest U.S. from Florida.
etrailer services and tech center were excellent. Cathy T.is exceptional!

Still going strong. We are considering more suspension enhancement in the future. etrailer will be our primary resource.



by:

They work as described............ Planned on installing "Never Fail Bushing" in place of the Bronze factory installed ones...............NOT POSSIBLE. The inside diameter of the bushing hole is undersized and not 11/16"............ Kind of disappointing. What do I do later when the Bronze bushings wear out??? Buy another set of equalizers??

Leroy,I contacted Lippert and it is possible to change out the integrated bronze bushings for never fail bushings on the sides of the equalizer. The original bushings can be switched out for 11/16 bushings.

23k miles last summer AL l Western U.S. Worked fine. Who knows how much better ride would be. Can't ride in tt to check.

John W.

3/16/2023

From the trip to Alaska and back with the incredible amount of potholes and frost heaves, tt handled it fine due to these equalizers keeping it from shaking apart. Only one loose trim screw in 40k miles. Highly recommended for any tt. Well worth the expense.



by:

I purchased this product to upgrade my suspension on a brand new travel trailer that I was going to pull to Alaska. I had heard that the roads could be a bit rough and hard on trailer suspensions and did not want to break anything because of the relative inflexibility of the stock system. The product was super easy to install, but I ended up using the longer shackle brackets that were in the suspension upgrade I purchased because I could not get the stock length brackets to line up correctly with the leaf springs. This resulted in a lot more suspension travel than I was anticipating, but seemed to do no harm as a result.

The trailer pulled wonderfully all the way to Alaska and back, and did not result in any major upheavals within the trailer. The extra flexibility in the suspension did make it a bit trickier to level the trailer however, requiring greater block thickness on the side that needed to be raised. But ultimately this was no big deal.

Ultimately I can only imagine how the stock system would have performed, and my imagination suggests that it would have not been a pretty sight inside the trailer.



by:

Installed them myself in a few hours. They are fantastic, work great, no problems.



by:

Easy to install. Raised the frame an inch. Much better than plastic bushings. Stouter system overall. Great investment



by:

The Equa-Flex equalizers are a nice upgrade from original cast rigid equalizers that came on our Forest River trailer. They help absorb road bumps into the chassis and interior of our travel trailer.



by:

The equalizer and shackle kit were excellent quality and easy to install on 5th wheel. Everyone at etrailer was very helpful and concerned about my receiving parts on time. We were on the road at the time and thanks to their efforts we were back on the road in 3 days. By the way, I installed these myself at the campground!



by:

Trailer rides much better and suspension is quiet. Also recommend installing with wet bolts.



by:

We are so happy to learn about etrailer from our friend. Our experience ordering from etrailer was so pleasant working with Crystal. She was very knowledgeable and everything that we needed to replace the springs on our trailer and recommended items that we would need to make our installation perfect! Thank you so much for being available. We will definitely recommend etrailer to our friends and family.



by:

Product arrived on time and in good condition. Installation is no problem, took about 2 hours. Test drove unit about 30 miles after installation. Must drive more miles before I can rate performance of the product.

Works good trailer seems to ride better



by:

Great product, great company to deal with. Install was a little challenging but worth it I hope. Took trailer for a test run after install, trailer rode smoother. The only thing i could add would be, if I have 2-1/4” shackle plates I don’t need the 3-1/4” plates, maybe reduce the cost a little.



by:

Works just as I'd hoped. Easy install and trailer rides much smoother. I installed on a tandem boat trailer and really helped out a lot!



by:

Ordering was easy and pain free. Shipping happened fast and the tracking was excellent. The correct parts arrived. It will be a few weeks before the parts are installed so I cannot rate them as to performance but when I do it will not have any bearing on the performance of etrailer.com as they did not make or brand them.



by:

Excellent shipping the product was pretty easy to install I have not pulled it anywhere yet I installed them on my 40 foot fifth wheel RV going November on a trip can’t wait to see had it Does thanks etrailer



by:

Looks like a nice product, but I was told that bolts and bushing would be included. The bushings appear to be installed, but there are no bolts leaving me short 6 bolts, 3 per side. Now i will need to order six more bolts or find them locally to finish my project. Those of you buying this product you will need to buy the center hanger bolt and the two shackle mount bolts per side.



by:

Had a bad experience ordering online last time (my fault). This time I called talked to Roger told him what I was looking for gave him some information he hooked me up with the right parts and got them right out to me. Awesome service!

    Yes the Equa-Flex Cushioned Equalizers # LC279687 can be used with a tandem Axle. All you need is a tandem axle trailer that has an axle capacity of 3,000-6,000 lbs and as long as your setup will fit the dimensions in the diagram I've included, you should be in the clear! I've included a video I want you to watch before ordering and installing. It will help keep the install short and simple.

  • Lippert Equa-Flex Cushioned Equalizers for 2010 Puma 253FBS
    In terms of axle capacity the Equa-Flex Cushioned Equalizers # LC279687 that you referenced is the correct kit, as it's designed for 3,000 to 6,000 pound tandem axles. To ensure these will work as replacements though on your Puma you will need to take a couple measurements on your existing equalizers. If you measure a horizontal length of around 5-1/2 inches between the bolt holes and a height of around 2-1/2 inches from top bolt hole to bottom bolt hole then they will work perfectly....

  • Are Longer Shackle Straps Required If Equa-Flex Cushioned Equalizers Are Taller Than Existing
    The difference in height between the old equalizers and the Equa-Flex Cushioned Equalizers part # LC279687 won't create a need for longer shackle straps. It may raise or drop the trailer slightly but that will be about all that is different. The important part is that the distance between the bolt holes left to right is the same or very close.

  • Recommended Lippert Equa-Flex Equalizer Kit for a 2021 Grand Design 22MLE
    Michael, it looks like your trailer has a GVWR of ~7,000 lbs which means it likely has 3.5K axles. So, since the Equa-Flex Cushioned Equalizers # LC279687 are designed to work with tandem axles that are rated from 3K to 6K, you'd be good to go.

  • comparing Dexter E-Z Flex and Lippert Equa-Flex Cushioned Equalizers
    Besides the obvious design differences there isn't much difference in how the E-Z Flex and Equa-Flex # LC279687 work or how well each one works. If I had to quantify it I would say that the Equa-Flex would stiffen things up a little more compared to the E-Z Flex. In general the E-Z Flex takes up less space so if there is anything in the general area that may get interfered with then the E-Z Flex is the better option.

  • Determining The Correct Replacement Equalizer And Shackle Straps For A 2017 Forest River 5th Wheel
    When replacing your trailer's equalizer and shackle straps it's important to first measure the hole spacing of the current equalizer and shackle straps. The suspension needs to be able to travel back and forth as you go over bumps and when installed correctly will form a "W" (pictured below). Too far inward or outward can bind up your suspension and eventually wear your leaf springs and shackle straps prematurely. Because there's a lot of thought put into this by the manufacturer you'll...

  • Do The Bushings In The Equa-Flex Cushioned Equalizer Need To Be Replaced To Use Wet Bolts
    The Equa-Flex Cushioned Equalizers # LC279687 comes with bronze bushings already installed in the eyelets so you wouldn't need to change them out in order to use wet bolts and lubricant. If you had an equalizer or leaf spring with nylon bushings then you would need to replace the bushing with bronze ones. I would just hang onto the bushing included with the wet bolt kits and save them for when the bushings need to be replaced so that you're not spending as much down the road.

How often to grease the wet bolts depends on how much use the trailer gets. If you do not use it very often then it is not working as much and the grease will not break down as quickly.
