These things look beefy as hell compared to online photos. These are WAY better then factory stock. I have them On my Big Tex dump trailer 90sr after snapping my stock ones. I haul small tractors and mowers, deliver stone and soil. Very satisfied with my upgrade.

Product is exactly as described. Very nice compared to the stock junk that was on my trailer. Easy to install looks good too. Can't wait to test drive the ride.

The E-Trailer team provided an awesome experience. The tools to research what I needed was easy and extensive. The ordering process was easy and my order was shipped and received very fast, thank you. I haven't installed the Dexter E-Z Flex suspension kit yet, but they look as advertised and I'm excited to try them out.

Installed on a 1999 5th wheel.camper because my old shackles broke. The trailer pulls 100 times better. If you are thinking of this upgrade dont hesitate buy it.

After a year it still looks and more importantly works great.

After installing my new E-Z Flex Suspension kit a year ago I have travelled close to 25k with out any problems and it held up even after breaking a leaf spring and then later the leaf spring bracket that is welded to the frame. I am super impressed with this product and wonder why Heartland does not use it when they build there trailers.

As a learning curve installing these. I made a tool to install bushings and found an air hammer made it very easy. Broke one trying to pound it with hammer. Plus had to ream out spring eye to make more round so bushing fit better. Other than that, worked well. Another hint is when you grease the pins, jack up trailer. I have a power greaser and could not get a couple to take grease. I lifted trailer and they all worked fine.

This eliminated the suspension squeak on my 12 year old 5th wheel. All of the plastic bushings were worn through.

Great product. As an industrial designer (retired), ...kept the machine shop, I dread the quality of pretty much everything I order. Sure, one bronze bushing needed to be pressed in further and a nut was missing due to UPS's classic handling, but the end product can only be described as 'OVERKILL'. Thanks for saving one very poorly designed Lamar dump load trailer ...requiring an axle flip to have any suspension travel at all.

One of the shackle assemblies had bad threading. etrailer was able to get an replacement sent directly from Dexter for free. Just installed and went for a tow. Very nice difference. Much improved ride. Install is a little challenging if you are an average Joe. Make sure you buy the right tools. 6+ Ton jack stands and air/hydraulic bottle jack from Harbor Freight, along with a decent impact and torque wrench and you can do this in a day.

Still working great. I wish this was standard on all trailers.

The Dexter E-Z flex Suspension is by far one of the best upgrades that I have made on my trailer. The ride and overall trailering experience is the best.

We got an excellent service from etrailer.com and we are very happy how the replaced Dexter Axle E-Z Flex Trailer Leaf Spring Suspension has been working on our fifth wheel trailer after owning it for a year. That is a very good quality part. Thank you again for all your help. [Two Thumbs Up]


Comments
We received a prompt and excellent service when needed with no cost to us. No complaints about the part what so ever. We just sold our fifth wheel, so this is my last comment.

Great product. Well made and solid. Fast order turnaround and delivery. Contents should be better packaged. Had missing parts. Called customer service and the missing parts were sent. They were friendly and helpful. There were no installation instructions. Though install is quite intuitive. I viewed some [online videos] which helped. etrailer web site was very informative which made my product selection with confidence. I’m 72.5 years young. Install is quite physical, but I gotter done. I am very happy with using etrailer. I would recommend etrailer and this product to everyone.

This is for people that USE a trailer. If you replace shackle links and equalizers once a year, this is for you. Mine showed up with some spring eye bushings missing, so the packing could be improved. Surprisingly, they wouldn't send me replacements or sell them separately. I ordered them from another vendor and installed the kit. Grease it every now and again and no wear to the pins or shackles so far. Well worth the money if your trailer is on the road every day.


Comments
Still as good as new. I would say it would be nice if the trailer didnt have [] axles because the equalizer is very close to the ground, but I have only dragged it hard once and it didnt hurt it that I can tell. Highly recommended if you daily your trailer.

Love it, i did not realize I had broken flex trailer leaf spring. After installing Dexter Axle EZ Flex Trailer Leaf Spring is so much easier to pull down the road. I still think SC is the worst interstate 95 section going North or South. Bridge vs Highway transitions are the worse in any state.

Thanks to Jessie @ e-trailer i received my order in a prompt and secure method. Although I have not begun the assembly yet because of weather conditions, I did inspect all the parts received and as per my previous experience with e-trailer they were right on. Install will be a breeze.

Great product ! Trailer tracks better now , so tire life is better,, going to order another suspension kit for another trailer I own. It is so nice being able to grease all the pins to make them last longer. Great company to deal with..


Comments
Suspension is working great. Being able to grease the moving joints is a real plus. Will be buying more Kits for other trailers I own.

After my linkage broke on my tow behind trailer, I watched an etrailer YouTube video that showed how easy it was to replace the equalizer with a heavy duty one. Everything worked just as described in the video. Im so glad I didn't go with the junk OEM

The staff was very prompt and courteous. I received the product within three working days and am very satisfied with the etrailer service and the product. High quality and has made a world of difference with the quality I feel while towing my FZ322 toy hauler loaded or empty. Much heavier system that rides smoother and more quiet than the manufacturers suspension.


Comments
Perfectly much improved ride. With the grease fittings and heavy duty construction and regular maintenance approximately every 5,000 miles there isn’t any evidence of wear in the shackles or pins. Well worth the money spent.

Very nice kit, everything was included and looks very stout compared to stock setup. Took less than 2 hours to install and would have gone quicker if I read instructions, didn't realize the center bolt was different from the rest until I got to the other side. So I jacked up first side twice. I installed a set of Sumo Springs at the same time.

We have a Sandpiper mid bunk 5er we bought 2 years ago as we upgraded from a travel trailer. As the driver I could immediately tell the improved handling pulling a 5th Wheel over the travel trailer. However, that was the extent of joy going to the fifth wheel. For two years we suffered with a bumpy ride as we towed our camper around the southeast. We began our journey to improve the ride with the Lippert flex air pin box which made a difference, but we were not satisfied. Next we moved from a standard equalizer system to the Dexter Ez Flex and the wet bolts. I will say we also upgraded our tires to the Goodyear endurance’s tires at the same time. Our first trip was 400 miles through some inner city interstates and some smooth interstates. The combination of all three components working together ( the pin box, tires, and dexter Ez flex system) made the ride enjoyable once more. My wife said that it felt like it used to when we towed our travel trailers. Now I will say it took money to get the ride we wanted, but it was worth it for the amount we use and paid for our RV. Please note that you will lose a little ride height moving from a standard equalizer to the dexter. In my case I lost somewhere around an inch based on my best guess, but I did not measure before and after. Overall I’m thrilled with the improvement we noticed.

I purchased this to replace the worn EZ Flex suspension on our 2011 Heartland Bighorn. The original EZ Flex was not a wet bolt, so I figured this was a good upgrade. I have read that Dexter had a bad batch of equalizer rubber and ours was definitely evident of that. The bumper material had completely collapsed and cracked such that the equalizers were hitting metal-to-metal. The nylon bushings and bolts were in good shape but the bronze bushings in the equalizers were worn through on the inner edges. We have towed our 5th wheel about 20,000 miles, coast-to-coast. I was surprised at the wear seen. Installation went well with one broken bronze spring bushing requiring a reorder. The rest of the installation worked well. I used two bottle jacks (20 ton for frame, 6 ton for one axle) and a floor jack for the second axle. A C-Clamp came in handy to center the spring on the bracket for bolt installation. 3-4 pumps of grease for each of the fittings. We'll see if it helps in a couple of weeks on Michigan spring roads.

Great service, questions answered promptly and accurately, package arrived before the promised time. I had no problems installing the product as the fitment was exact thanks to etrailer product recommendation. Installation of this item should be done by an accomplished mechanic and in a well equipped shop. My 5th wheel is 32' long and the installation requires at least 3 jacks to lift the trailer and axles and to manuver the axle height in order to install the pivot bolts. Product smoothed out ride to some degree but the reason for my installation was due to worn out bushings which made a click/pop noise while driving over uneven surfaces.
