We broke down on a Saturday near Cincinnati and couldn't find any parts, so I called etrailer and luckily they had a wet bolt kit in stock. They shipped it next day, which means business day, next day, aka Tuesday " thanks UPS ". I had the kit installed by a mobile mechanic and I was back on the road by 3:30pm.



So far so good, and its easy to maintain. Although sometimes I wonder if the grease is getting too some of the bushings


Had to replace the axles and decided while there, just do the whole suspension too. Got the axles directly from Dexter but purchased the suspension kit from etrailer. Replacing the equalizer was the easiest part of this project and if I didn't have to replace the axles, probably would have had it done in under 2 hours. Time will tell how well it rides and the tires wear.


Really liked the kit as soon as I opened the box. Well made,& much beefier than stock. Went together pretty easy. Probably spent the most time figuring-out where to put the jacks. My bushings were completely worn-out, so I did have a bit of an alignment issue. That was completely on me. Due yourself a favor and don't wait too long like I did.

The results were very noticeable the first trip out. Took almost all of the slap out of the trailer suspension. Installed this kit on a 2003 Sierra 29f Fifth-Wheel toybox trailer. Primary useDirt Bike Mike is Off Road riding in the SoCal desert.



Working very nice. Noticeably smother ride.

@Fateddie That's great, we're glad to hear that!


I had morryde LRE suspension system on my 5th wheel and it failed after several emails that I did not get a response to I ordered these, cut off my old suspension and installed these 2 days later i towed my camper 16 hours south and it worked great it eliminated the "bucking"i was experiencing overall way better system I'm very pleased

It is holding up very well


Seems to be working well at taking away the big jolts from the road and giving a much smoother ride to my trailer. Way more substantial than the stock system that came on my trailer. It was about a 6 hour job for me to do myself, from begining to end. That's including getting all my tools ready, cribbing the frame, clean up, etc.
If you have a stock equalizer suspension I highly recommend this product!


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.


I had these installed on my 2022 Grand Design Imagine 17MKE. I haven't had the trailer that long, but drove it back from TX for about 13 hours, and a little around town here in the Phoenix area. Since having the Dexter E-Z Suspension with wet bolts kit installed, I pulled it home, which was about an hour of driving. The trailer was noticeably smoother in pulling. I noticed less jarring, and it was smoother on my truck as well. I am towing with a Anderson WDH. I do not know about the condition of the OEM equalizer parts that were taken off, but I found this camper in like new condition, and dont expect there was much wear an tear on the original suspension. If anything changes, I will try and update this review.


It seems to help with pot holes or large bumps, when I replaced old hanger bushings they were plastic trailer had 6000 miles on it and bushing were almost wore though. Good product buy hanger kit too.



Helps with sway helps with maintenance

@Charles Glad to hear it's working well for you!


The parts came in a timely manner and installation went as expected..... It is great to have greasable bolts!!!


I installed these on my striping trailer and frequently travel to other states. The trailer rides sooooo much better. The grease zerts and brass bushings keep it from being squeaky. I will put this on any new trailer that I buy.


Used their chat feature for help putting together a non-standard dual axle equalizer/shackle package w the larger 7.75" EZ-flex and also needed the longer 3.125 shackle. Recommended the Morryde wet bolt set up. etrailer went the extra yard and provided a free return label to correct a mistake in the order and everything ships FAST. Will use etrailer again. Thanks


I am so pleased with the performance of this product! I love improving the things I build and take great pride in quality. I was so relieved to have found etrailer. Installation was a breeze and now my home moves with ease. Thanks etrailer!


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.


the shackle bolt grease zerk fitting are different than the single bolts seem to be a metric thread and the head is to small for grease gun to connect


Much beefier than previous shackles. Quick shipping and prompt arrival. Installation went smooth. Two phone calls to customer service, 2nd asking for proper parts. Not etrailers fault. I needed longer eye bolts after disassembly. Customer service we more than helpful both phone calls. I ended up having to order parts from a different website. Not a really big deal. Great experience as usual.


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.


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

great price!

@Francis Glad to hear, Francis.


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. 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.


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.



Good, no problems. Only difficulty is in greasing the pins, it is very hard to impossible to grease some of them but if you hack up the trailer by the frame, is piece of cake


Best thing we ever did to our camper ! Our suspension is great now we can go down the highway with out thinking about it!
Ever one should check and update their suspension! What a difference in your ride !!!!


It feels much better when towing my trailer and I have a peace of mind that the suspension has been improved from the original. Less porpoising, especially over the local bridges.


I’ve had this setup on the trailer for 1 year, works great and was really impressed on the thickness of the metal on the shackles. Nice being able to grease the bolts as well. Good upgrade highly recommend.


These items replaced the same items which I had installed years ago. The originals performed great. I needed to replace them due to returning to Wisconsin in the winter from Arizona. This trip happed in 2019. Due to Covid and not traveling, I didn’t perform maintenance. When I began preparing for our trip to Florida, the grease serts on the spring ends would not take grease. It required me to cut and grind off some suspension parts and replace them. Completely my fault. The first set worked so well I replaced them with the same set.

  • How to Determine Which E-Z Flex System for Forest River Arctic Wolf 3770 Suite
    It looks like the Forest River Arctic Wolf 3770 Suite has a GVWR of a little over 14,000lbs, so you likely have 7000-lbs or 8000-lbs axles on there, which would make the Dexter E-Z Flex Suspension Kit - Double-Eye Springs - Tandem Axle - 8,000 lbs # K71-653-00 the correct E-Z Flex system. You will want to verify your axle capacity, that the axles are spaced 35" apart center on center, and that the length of your current equalizer is roughly 7-11/16" long from the center of one bolt hole...

  • Equalizer Upgrade Kit for 2020 Shadow Cruiser 193MBS
    When choosing an upgraded equalizer like the Road Armor Shock Absorbing Equalizer Kit - Tandem Axle - Qty 2 # LC696740 you want to choose a kit that is as close as possible to your current equalizer width. The # LC696740 measures 6" from center to center across. I recommend measuring your current equalizers in order to make the best choice. If your current equalizers share the same 6" measurement, or are very close, then this kit will work well for you. This is the only size available...

  • Will the Dexter E-Z Flex Suspension Kit K71-653-00 Fit a 36 Inch Axle Spacing
    I do have an option for you but there are not any Dexter E-Z Flex Suspension Kits designed specifically for an axle spacing of 36". This 36" axle spacing is common for tandem axle slipper spring systems but not double eye tandem axle leaf spring systems. However, I spoke with my contact at Dexter and they stated the Dexter E-Z Flex Suspension Kit part # K71-653-00 should still work for you, as long as you have double-eye springs, as it is designed for a 35" axle spacing.

  • Locating Replacement Leaf Springs for Dexter D44 Tandem Axles and Recommended Upgrades
    In order to find the right replacement leaf springs, you will need to raise the trailer up and take some measurements on one of the existing springs. This type of information isn't typically provided by trailer manufacturers and it's not something that can be determined by the axle capacity (many different leaf spring lengths could be used with 4,400 pound tandem axles). With all the weight lifted off the leaf springs, you will just need to measure their length (from the center of one...

  • New Leaf Springs & Equalizer Upgrade on Grand Design Reflection 312BHTS Travel Trailer
    So starting with the question about weight, since you have 5,200 lb axles, go with the 5,300 lb leaf springs, or even 6,000 lb leaf springs would be okay, but I do not recommend going with springs rated less than the axle capacity. The number of springs doesn't come into play, the capacity is what really matters. As for fit, we don't have a way of knowing what leaf springs are on any trailer - the same goes for the equalizer - so you'll need to do some measuring. Leaf springs do flatten...

  • Cushioned Equalizer Recommendation to Replace Lippert EquaFlex 279688

I would go with the Dexter EZ Flex kit part # K71-653-00.

  • Would the E-Z Flex Equalizer # K71-652-00 fit a 1997 24J Fleetwood Travel Trailer
    The # K71-652-00 is designed to replace equalizers that have the lower two holes 5-1/4 inches to 6-1/4 inches apart (see pic). You will need to measure the dimensions of your current equalizers to determine if these would match up and work for you. For a wider equalizer you would want the # K71-653-00 instead as it has a range of 7-1/4 to 8-1/4 inches.

We also have a MORryde part # MR34AR which would be my first choice as I prefer the way these rotate to provide the cushioning and MORryde just has a really good reputation in terms of performance and quality.
