Missing parts - Missing two shackle links and eight backing plates… please overnight missing parts as I am stranded and unable to leave…

Customer Service will reach out to you.
-- Etrailer Expert Sierra K - 12/20/2021


etrailer support staff gets 5 stars. However...
kit I received was incomplete. Bushings were missing, two shackle links and a shackle link assembly were missing. Additionally, one of the shackle link assemblies would not accept its' mating link - the bolt shafts were spread apart.
one of the equalizer assemblies did not have that gold anodize coating, another had incomplete anodize coating. see pic.
etrailer staff shipped me the bushings and the shackle link assemblies to complete my project. As for the finish, POR 15 gloss black is a lovely color. The issue here is with Dexter, not etrailer


The ride seems to be smoother on the trailer. If I could ride inside it under way it would be easier and more objective than from the towing vehicle to say how improved the trailers ride is. I think the chassis experiences far less jolting that before.


I think this kit was returned or repacked. All parts thrown in together, no protection for the powder coated parts which are now chipped.
The Dexter kit itself is a great upgrade for trailer suspension.


Love the system on my 20k 40 foot toy h ouse....Alfa...

Love the system...miles of travel

Installation was straight forward. I like the fact that you can easily grease each pivot point via the wet bolts. Upgrading the bushings from plastic to brass makes me feel its meant to last.

Works well - hope it lasts. Replaced like for like on my 2012 Road Warrior after the original failed and allowed the middle and rear tires to touch when travelling. The rubber shock degrades and allows the hinge to travel farther than its designed to go - allowing the tires to move close together. I do like the wet bolts and brass bushings. Ill be sure to watch for excessive wear and replace if necessary.

It definitely quieted the crunches, clunks and rattles. Much smoother ride. Not at all cheap though.


Great product, easy to install, substantial improvement over factory setup

EZ flex suspension update, approximately 6k miles, trailer follows great, handles much better definitely recommend!

Good stuff


The product was delivered in good condition. It was missing six of the wet bolts and I called etrailer and they looked it up off my phone number and I had them in about four days so I’m happy with that. The trailer does seem to ride better It took took me and my son about 4 1/2 hours to install but I have a triple axel. Some of the old bushings didn’t want to come out and I took a 5/8 drill bit and ran it through the leaf spring ends and they come right out. I read some of the other reviews on Heartland trailers and noticed the middle axle runs crooked. Mine was the same way. This kit has straightened my center axle out.


We installed the suspension upgrade kit last year. We live full time in our vintage coach. We have always been happy with the service we get from and have purchased several things for our tow vehicle and travel coach.


Had these EZ Flex installed on my triple axle toy hauler. Couldn't have been happier with the instant improvement from the old traditional stock suspension system. The ride was smooth and steady with no more bounce from the trailer! I would recommend to anyone with trailer suspension issues.


The things that separate etrailer from everyone 1.Price-always lower than anyone...2.Selection-always have what I need or will get it for me...3.Videos-show the product and what it is...4-Installation Help-Have videos and great tech staff on hand..5-Shipping-free and fast,let me know when its coming...6-easy to use website that makes shopping a breeze.. Want to improve? ? Pre-screen videos by others and only include those that are correct and helpful then pin onto your site for that product!!!! I I usually look at your vids and then on internet to get a good prospective about what I am getting ready to do . Measure twice cut once....Would save me time from scrolling through bad vids !!!!!!


The product is superior to the original equipment


One of the piviots came in with a broken grease fitting that was a real pain toget the broken piece out.After waiting 3 weeks to get the kit I did not want to wait for another one so I fixed it myself.
I have not installed it yet so can not say how well it works yet.


As advertised, easy installation, and clear instructions. Very robust and I look forward to experiencing a trip with the new set up. Very happy with my etrailer interactions.



Product is very well built. Fit was perfect. Looks like it will work way better than stock suspension. Fit just like original.


Nice parts well made shackles are twice as thick as oem ones. Easy to install.


awesome service!!!
