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]

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.

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.

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.

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.

I love the Dexter EZ flex equalizer/shackle system. I installed my first set on a 20’ equipment trailer with 4000 lb axles. It really made the trailer much more quiet both when going over bumps and when sharp turning/backing. E trailer has wonderful customer service. My first set arrived in just a few days. I have since ordered two more sets in the last year for additional trailers I own (28’ enclosed goose neck and a 26’ fifth wheel camper).



- K71-653-00

Have had product for about a year. Only used trailer 14-1500 miles with product installed. Trailer seemed to pull easier after rebuilding undercarriage . Fuel use may have been a little less but wasn't huge difference. Don't believe the ride was (in trailer) different a lot of stuff behind axle was on floor but every trailer we have had did that. We probably ran a little faster and felt trailer pulled better but the roads were rough in places and stuff bounced around. I like the design of parts and noticed some new trailers are using these equalizers. We put these on a 2010 keystone raptor with tandem axles they are far superior to original equalizers.

Very heavy duty and easy to install.Seems to help cushion the ride on my fifth wheel toy hauler.I was over 3000 miles from home when I discovered the old shackles had failed and they shipped these to me and I received them in a day or so.

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.

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.

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.

The Dexter EZ Flex equalizer system with heavy duty shackles, combined with Sumo Springs, made a huge difference in the amount of trailer bounce I experienced in towing a 34' travel trailer. The entire rig is much more stable and under control. Towing went from scary to mildly pleasant. I was very pleased with the customer service I recieved and would recommend them to anyone.

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.

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.

This is an excellent upgrade for any trailer suspension. The bushings in mine were worn out so it was time for a rebuild. All the parts are first class and everything fit together perfect. Don't get in a rush and allow yourself plenty of time. The improvement in the ride was noticeable right away on our first trip of 400 miles...and it was a joy. This rebuild was done on a 1997 Alpenlite 34' fifth wheel

  • Dexter EZ Flex Equalizers for 6,000 Pound Axles on a 2006 Heartland Bighorn 5th Wheel
    The length is good on the EZ Flex system # K71-653-00 but the height may be different depending on where you are measuring that 4-3/4 inches. On the EZ Flex the distance from the center of the mounting hole to the center line between the 2 bottom holes, straight up and down, is 2-7/8 inches. If your 4-3/4 inch measurement is diagonal then you will be good to go with this kit. For a u-bolt kit you can use # APUBR-9. The shocks might actually feel more effective with the EZ Flex kit...

    For a standard replacement equalizer for your Dexter 13-122 equalizers you'd want the # TREQE1 or for a cushioned version you'd want the part # K71-653-00 which comes with new shackles and bolts. For a kit that includes new bolts, bushings, and nuts for use with the # TREQE1 we have the part # LC281285 which would work great as well. This is a never fail bushing setup that does not require any greasing as well.
