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. To begin, insert one bushing into each of the bolt holes on the 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).

These will be going back. Lippert did a terrible job prepping these for shipment. They showed up with evidence of metallic grinding, dropping, and less than a quality piece. The bubble wrap that was around the pieces wouldn’t protect a Christmas ornament from the dollar tree. Definitely not going on my trailer like this.

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.

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

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.

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.

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

Replaced original equaflex units with these, very nice!

Fast shipping and installed easy, had trailer completely lifted which helped in attaching shackles to equalizer.

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.


Comments
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.

Usual great packing job by etrailer for heavy items.

These were a direct replacement for my existing Equa-flex brackets on my fifth wheel RV. The originals lasted six years and needed bushings and rubber cushions were showing their age. I was able to purchase a set of these that had been returned for damage to paint. They came to me in the condition described by customer service rep. Good job as always etrailer! I also replaced the rest of bushings/bolts with a Never Fail kit I'd purchased earlier. That part of the repair was more difficult. The plastic bushings are difficult to fit in the spring eye and the threads on the bolts and nuts can strip easily if you're not careful.

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.

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.

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.

by:

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.

Installed today on 38 foot fifth wheel with dual axles, 4 hours start to finish. Also changed to the heavy duty shackles and wet bolts. Fairly easy once you figure it out.

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.

Seems to help with the ride. I would buy them again

etrailer was great! This product should last longer than 3 years. Not very happy with Lippert, but this is not any fault of etrailer. Thank goodness they had the replacement parts. etrailer is one of the best companies I have dealt with!

Part arrived in good time and in good shape with bronze bushings. Works great

after a year they are doing great. traveled just over 9000 miles with the new springs and the 5th wheel tracks a lot better.

The product was easy to change. I replaced the equalizer with the same replacement. The little arm that the shackles hook to was broke.
