Bumpy roads and trailer bounce can make towing a chore. The Equa-Flex Cushioned Equalizers use built-in rubber cores that soak up vibrations and minimize chucking—the back-and-forth motion that happens over uneven pavement. Instead of transferring that energy into your trailer, the rubber flexes to smooth it out, giving you a ride that feels calm and controlled even on rough surfaces.
Standard cast equalizers wear down fast, especially under weight. These equalizers are made from sturdy steel with a corrosion-resistant yellow powder coat finish and come with durable bronze bushings pre-installed in each 9/16" bolt hole. They’re built for tandem-axle setups rated from 6,000 lbs to 8,000 lbs per axle, so they hold up to hard use without losing their strength or squeaking over time.
Swapping out factory equalizers doesn’t have to be complicated. The Equa-Flex design drops right in place of your standard equalizers, measuring 7-1/2" center-to-center across the side bolt holes and 4" tall from the bottom to the top bolt hole. Installation is straightforward—just add your existing shackle straps and suspension bolts (each sold separately)—and you’re ready to go. Once installed, you’ll feel the smoother ride right away.
This illustration depicts a tandem axle trailer suspension system equipped with the Lippert Equa-Flex cushioned equalizers installed between the leaf springs and hangers. It visually supports the installation instructions and helps users understand where the equalizers integrate within the suspension components.
Every jolt that hits your suspension also hits what’s inside. With these cushioned equalizers taking the punishment instead of your trailer frame and gear, the whole setup feels tighter and more stable. It’s a simple way to cut down on wear and tear, protect your cargo, and keep your trips quieter and easier mile after mile.

Ratings & Reviews
Fast shipping and installed easy, had trailer completely lifted which helped in attaching shackles to equalizer.
DIY install traveled 8000 miles without a problem. 5th wheel hauled extremely well with the new suspension.
These have made a huge difference in the handling of our fifth wheel. A bonus is the are very quiet. No more squeaky trailer noises. Very easy to install as well.
Well, between your "Tips for a great review" and "Not appropriate for a review" I'd say you don't really want an honest review. My experience though, box had a large hole, glad there was no loose parts. Of real concern though (safety/warranty) was the fact that the pivot points were assembled with no grease at all, totally dry. Glad I checked.
The product is amazing; however, the kit didn’t come with the Stover Nuts to put it all together. I’ve had the kit for a year and just installed it last weekend and noticed it came with no nuts.???? And trying to find 7/16 x 20 Stover Nuts is almost impossible...but I did. I would recommend a little better quality control on the items required to be in the box. I no longer need them since I’ve already purchased them from another source.
Fast Free shipping arrived as stated. Best price. Replaced 10 year old Equa Flex. The rubber was cracked and compressed. Installation was simple. Came with bronze bushings. The Box it came in had other items and was very heavy causing the box to break down.
Just to say shipping was great and fast, install took place several days later and that went very well also. Plans are to try out the new install in the coming weeks, I see no problems, very satisfied from cost to install even with age and fiscal handicaps.
Thanks etrailer for appears to be a solid design product. I would recommend this product over a flex design after 4 years needed replacement.
Have a 30' toy hauler and first added Sumo shocks which made a difference but after adding these Equa - Flex cushioned equalizers what a BIG change in the ride and towing. E trailer shipping was very fast and they were very easy to install . To me this is a must for people with an RV.
Excellent product. These a a big upgrade from the stock. Thanks to Bob and the crew for installing these. See the video of the installation.

Works great. Smooth ride. Would use again.
I upgraded to the 6-8000 lbs. Equlizers on my 2014 Redwood fifth wheel .
I have had 2 leaf springs break within 2 months . I did some reasearch and found an issue with the shackle bushings failing so I also went with the heavy duty wet bolt kit.
Included is a video of the equlizers doing their job.
product shown has new top pins which were not included, also the packaging was 1/3 destroyed. My old pins do not have grease fittings, so no way to grease the Equa-Flex devices.

With these Equa-Flex cushioned equalizers, they come with the Never Fail bushings which are self-lubricating so that you do not have to re-apply grease constantly. You can add a wet bolt like part # LC126238 or # LC126197 depending on the length that you need. If you do you will want to use bronze bushings as the grease will eat away the never fail or nylon bushings.
Have only put about 3500 miles on these replacement equalizers but they appear to be getting the job done. I'm a little surprised at how much the rubber bushing portion is already compressed but will see long term. The order from etrailer was handled correctly and timely. Happy with the company.
This is the 2nd time I have bought new equalizers. The first replacement set were abused by leaf springs that were too long. This caused a binding of the equalizers as the long springs pushed to the center and tore up the rubber bushings on the equalizers. Before a long road trip I had custom leaf springs fabricated and installed new equalizers. All is well now.
Great product. Made a big difference from OEM. Definitely recommend them.
Received exactly what I needed and on t ime
After 10 years of wear and tear it was time to replace my equaflex system. As always etrailer staff was very helpful getting me the correct replacement parts and any upgrade parts I had questions about. Shipping was fast and the package came in damage free. Installation was a breeze and straight forward. I also added wet bolts to the spring hangers and shackles. A very good upgrade for most RV suspensions. Very satisfied customer and etrailer is definitely my go-to company.

1 year after installing and roughly 18,000 miles everything is working great. No sign of wear. Great product. Definitely recommend this upgrade for those that have the stock equalizers.
The order in which I looked for and found on your page was sent to me in exactly the time frame you said, opened it up and All was there perfectly thank you very much
Easy to install, soft brake action eliminated the pivot flip. Highly recommend them. Buy the grease zert bolts and zero issues for as long as you own the trailer
Received the equalizer a little after lunch today. Had the passenger side of the trailer done in about an hour after some choice words getting the old one off. Putting this in was simple, and should make a good ride and stop wearing my tire out.
Very easy install—removed wheel on rear axle and plenary of area to work. Reused hangers and bolts. Installed in about 90 minutes. Looking forward to seeing the difference in handling
Looked at another brand, decided I liked the Lippert better. Although it was $[XX] more than where I started I was willing to pay the extra due to it having a variable width and it being heavier built than the product I was looking at. Paula was excellent in assisting me with this product, (4) springs, u bolts, wet blots / shackle kit.
I bought these to replace the worn-out ones I had on my trailer. It was approximately two hours install per side. I purchased all new standard bolts with never fail bushings along with all new straps. I was told I could replace the brass bushings with never fail bushings when I purchased the set. When I received equa-flex equalizers I noticed they all had pressed in brass bushings so I was not able to use the never fail bushings. I had to go down to the local trailer store to to purchase six wet bolts. All in all I am happy I just have six extra bolts and six extra never fail bushings.
No longer worried about my worn out leaf springs & old equalizer hardware.

I am glad that nothing was missing or damaged. When this is being installed it is recommended to add lubricant to the pivot points. Please take a look at timestamp 9:35 in the video below to see what I mean.
