Video Transcript for Dexter Axle Trailer Suspension - Leaf Spring Suspension - K71-657-00 Review

Today we're going to be taking a look at the E-Z Flex Heavy Duty Rubber Suspension System. This system is available for Tandem axle applications with part number K71-653-00, and for triple axle applications with part number K71-657-00. It replaces standard trailer equalizers and loose spring suspensions. This is designed for 1 3/4 inch wide double eye leaf springs. It's going to deliver smoother tailing when compared to traditional leaf spring suspension systems. It's going to feature this nice rubber core.

This isolates and absorbs damaging road shocks before they hit the trailer frame, and the contents of the trailer. The rubber core is going to last a long time, and it won't be effected by the elements. It's an easy installation. It does not require welding, cutting or grinding of the trailer frame. It's going to include all the hardware needed for the installation. The system itself is made from a very strong endurable steel construction.

It's going to feature a protective finish, it's going to keep everything safe from the elements, so you won't have to worry about rust or corrosion. This system does offer multiple grease zerk fittings for easy maintenance. You'll notice that on all the bolt heads, here on the shackles, we're going to have grease zerk fittings. On the new hardware, this hardware attaches to the other end of the leaf spring that would not attach to the equalizer. It's going to come with your new bushings, your new hardware, and each bolt head's going to have a grease zerk fitting on it. Then on the equalizer itself, there's going to be two grease zerk fittings.

It allows for easy maintenance. This is going to ensure that your set up is always well lubricated and quiet at all the moving components. It's very easy to apply grease. You just attach a grease gun, pump in the grease and then it's going to lubricate the moving components. This is going to replace Dexter Standard Equalizer 13-122.

If your equalizer has that number stamped on it, then this system's going to work great for your trailer. If you cannot find a stamped number or if you have a different brand of equalizer, then you'll want to take a few measurements to verify that this system will fit your application. For instance, your axle spacing must have a separation of 35 inches from the center of one axle to the center of the other. The distance between the lower bolt holes on this system will flex between 7 1/4 inches, and 8 1/4 inches. Then the bolt hole diameters are 9/16ths of an inch. If the spacing of the holes on your equalizer is between those measurements and the bolt holes have a diameter of 9/16ths of an inch, then this is going to work for your application. Again, those bolt holes that we're measuring from is from the center of this one to the center of this one. Those lower holes on your equalizer. The shackles themselves, these are included, all the shackles necessary. These are going to have a length measurement from the center of bolt hole to the center of the other bolt hole of 2 1/4 inches. These are designed for axles that have a capacity up to 8,000 pounds. That's 8,000 pounds per axle. I went ahead and assembled it just to show you what it's going to look like. Give you a good idea of how it works. We'll go over all the components that it comes with. It's going to come with these bolts right here. Again, these are going to attach to the other end of the spring that does not attach to the equalizer. Comes with the bolts, the new bushings and the new nuts to get those installed. You're also going to get all the necessary shackle straps and the hardware necessary to attach to the equalizer and to your leaf spring. Again, it's going to come with the new bushings. Those would go in the eye of the spring, and it's going to come with the bolts pre-installed in the shackle. You'll need to place this shackle on, put the bolts through, and then tighten all the hardware. I do want to mention that these bolts have the splines on them, so that means that these bolts will have to be driven into the mounting location. Also here, it's going to come with the new center bolt. This is for the equalizer to be suspended from the center hanger. That's also got the splines on it, that'll need to be driven into the location as well, and it's going to come with a new nut to get all that installed also. Really nice design, and again it's got all the zerk fittings on it. Which is going to allow for easy maintenance, it's going to keep all those moving components well lubricated, which is going to benefit when it comes to having a quieter system. That's going to do it for today's look at the E-Z Flex Heavy Duty Rubber Suspension System.

My 10 year old Toy Hauler was in need of some TLC. I dry camp 98% of the time. Traveling down very dusty and bumpy roads. The factory equalizers had plastic bushings that had failed. The Dexter Ez-Flex came with new bronze bushings and all of the hard-ware. It took me and a friend approximately 5 hours to install these. I have only pulled the trailer once since the install, but I could notice a difference right away. I like the fact that there are bronze bushing and I am able to grease them myself. I highly recommend this product if you do a lot of dry camping and going down rough dirt roads. I should not have any other problem with my load equalizers. The staff at etrailer was very helpful Rick S. and Michelle S. keep me informed each step along the way. This is the second big purchase I have made with etrailer and I highly recommend them and will use them again. Thank You 375118

The product is sturdy and built well. I already had prior experience with Dexter parts and these are manufactured with the same high quality. The instructions were easy to understand, and the Install Video that e-trailer had was EXTREMELY helpful. My installation went perfect and I had no issues. I road checked after and it felt smoother. Headed out this week for a 300 mile trip! Thank you e-trailer! 573124

This system made my 30' three axel equipment trailer ride like a Cadillac! Its so smooth when empty I almost forget I'm towing it. With a 13,000 lb excavator on it it's smooth as silk. I'd recommend this system to everyone who has a trailer. 448090

This is an excellent upgrade from what came stock on the trailer. It is heavy duty, rides great and is very well made. I will be upgraded my other trailer with this kit soon. My only complaint is with the packaging. It was damaged in shipping and missing two straps, etrailer sent two replacements out right away. The smaller parts need to be put in a separate box or something. 424465

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


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. 496077


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.

Installed on my wife's 2-horse gooseneck trailer with living quarters, along with flip kit for axle to raise trailer for leveling with higher truck. My wife believes the ride was much smoother for the horses based on less anxiety in horse's demeanor when unloading after trip. 315247

etrailer is probably the best one stop trailer solution on the web. I just fabricated my own deck over dovetail tailed from scratch. I ordered just about everything I needed for the build. The sales staff are very knowledgeable and professional. I highly recommend etrialer to anyone weather your rebuilding your trailer or fabricating a new trailer, they pretty much have everything your looking for with very good pricing and they stand behind every product they sell. 359320

I've not actually towed on this product yet as I only just installed it. The product is solid and easy to fit with clear instructions that make installation easy. I chose to replace the leaf springs at the same time. Like others have mentioned in reviews, the packing isn't just terrible, it is completely absent. The heavy contents are just tossed in a box and while that is bad enough, it presents a significant risk to the grease fittings on the EZ-Flex unit. Dexter (not etrailer) need to get that sorted out. I'd have given 5* if it wasn't for that issue. 565951

Would have loved to write a great review as the product appears to be well built and I like the ability to lube all the spring shackles. Unfortunately one of the bolt patterns does not fit my trailer. It would help if ALL the bolt hole measurements would be displayed in one place - so that you would know prior to ordering if things would fit. 234003

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


The installation is pretty straight forward, however with the trailer weigh and spring strengths it was quiet a lot of work. I have air tools and jacks to work with and it took about six hours. Didn't realize how bad my bushing were worn until it was apart. Camper is a 2013 with about 15000 miles and the plastic bushing were considerably worn. With E-Z flex installed, all the creaking noise is gone, tows a lot smother, still some chucking, but well worth the money and time. Great product and great service from etrailer. Thanks 267849

Ordered on Sunday it arrived on Friday and installed on Saturday went in easy, hardest part of this job is jack up the trailer. I used two jacks and lots of wooden blocks . All parts fit perfectly every thing was there no complaints. Going on the road next weekend to test the ride of my trailer, hope this will fix my rough riding trailer. It took me 5 hours to install this kit and adjust my brakes , I'm 60 years old so you can do this yourself 570169

I think they will be great. They are installed and I will be traveling soon on the new suspension. Thank you etrailer for youyr good products RV manufacturers are totally missing the boat and have absolutely no regard to quality in regards to the cheap suspension parts they put into these trailers. It just does not make any sense to put such cheap bushings. As far as I am concerned the whole RV manufacturing industry are very inconsiderate of there retail customers. 229233

I installed this Dexter E-Z Flex om my Keystone Cougar in about 5.5 hours in my driveway. I also installed the complete wet-bolt kit at the same time. I have taken many trips since installing this, including a trip from Cali to Yellowstone and back, and I have to say the quality of the ride has improves so much that it is near perfect! The rough roads and pothole are handled so much easier and I have less fatigue at the end of each days drive. Getting under the rig to lube these has been very easy and keeps things smooth and quiet. Do this upgrade! You won't be disappointed! 323299

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. 454958


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.

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 538869

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


I put this set-up on both my tandem boat trailer and a 7,000# enclosed construction trailer. Prio to the boat trailer was experiencing a blow-out virtually every other trip. Thought I had a tire problem. After rebuilding the suspension system... Blow-outs are a thing of the past. Trailer tracks extremely well in curves at high speeds. On the construction trailer I had a spring eye bolt fall out after installing this kit. I have no idea how or why but I always give the trailer a look over any time I stop. Did a mcGyver to get it back to the shop where I installed a standard suspension bolt. Been going that way ever since... 269088

Some of the wet bolts dont lube well at all. But that was the case when new. Otherwise, all is good on both trailers. Still glad I made the upgrade.

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


So far so good. Survived the first 1000 miles since installation without any problems. The wet bolt system has quieted the suspension on the trailer considerably. No more low speed squeaks/squeals or groaning from suspension flex in tight turns and bumpy roads. The hard rubber baby buggy bumper pads between the opposing arms are holding up well and do absorb some of the road hazard shock rather than transferring the impact directly to the trailer frame and contents. Really big bumps still rearrange the contents in the back of the trailer, but everything rides nice otherwise. 385807

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


This is probably one of the best products you can buy when fixing up a trailer where everything is egged out and wasted. Bear in mind that all spring hangers need to have the same dimesnsion from the bottom of the frame to the center of the holes. I didn't know this until the instructions revealed that. If your center hanger is tall, and end hangers are short, your springs will sit at an angle. So, provided all your hangers are the same, it's a quick swap. If they don't match, there will be welding required as well as a bunch of measuring and fabrication. 315219

Replacement of original 10 year old equalizers was fairly easy except for the old bushings in the springs, it took a lot of beating. Did not follow the instructions to remove axles, did 1 side at a time. I did replace the straight grease zerks and installed 90 deg zerks, instructions said the zerks were 1/4 28 thread, that is wrong they are 6mm 100 pitch thread. Great product will be ordering more parts soon. 556086

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. 561493

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


I found the hardware so much hardier then the original hardware. I read several articles about replacing the poorly equipped suspension hardware on campers that can leave you stranded and with a long camping trip coming soon I didn't want to take chances with the old suspension components and with the idea that the Dexter E-Z Flex system will help with smoothing the ride is why I went this way. Your sites reviews and installation videos were very helpful. My camper has LCI axles so I had to check through your reviews so make sure the E-Z Flex would work with my axles. I did find my answer and the E-Z Flex fit perfect. The directions that came with the E-Z Flex were only good for the torque settings. Your video was much more helpful. It took me longer then expected, mostly because I should of had heavier jacks and jack stands and had to improvise some. I haven't had the camper out on the road yet so I cannot comment on the ride, but it feels good knowing that I have a really good suspension under the camper now. Overall I am very pleased with the product and with your help selecting and installing it. 368934

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. 234675

We replaced the leaf springs and the equalizers at the same time with products from etrailer.com. The Dexter equalizers were much better than the stock product and easy to install. The leaf springs were exactly the same as those we could purchase locally and at a significantly reduced price. Well done etrailer. 501835

The EZ Flex equalizers did everything as expected. The shipping for this kit was subpar. The hardware was not packaged and all the parts beat each other during the shipping process. Also, there was 2 packets of copper colored grease that got punctured during shipping (due to zero packing/bubble wrap) and that messed up the majority of the instructions. I contacted 3 different people with Etraier (Adam, George and Angela) and neither were apologetic to how I received my package. I did however receive a canned response of "without honest feedback from valued customers like you we would not know where we need to make improvements" and I was expecting just a little more from Etrailer. The level of customer service prior to buying is top notch. I will give them that. 436306

About as simple a swap as you could expect. Tear off all your old stuff, throw all the new stuff on and voila! A couple of floor jacks, and 2 hrs max. Great time to swap out your junk Chinese wheel bearings too. No major ride change or anything, but at least I know the links aren't going to fail like the OEM ones did. See pic. 285667

I was reading about suspension upgrades in an RV newsletter and I decided to check the Dexter EZ Flex out. After reading the reviews and viewing the installation videos on your website, I took some measurements and decided that these would work the best for my 2017, 28ft Pioneer Toy Hauler. It has tandem 4400# Dexter axles and springs and was a direct replacement for the stock equalizers. It took me 4hrs from the time I unpacked the parts to finishing the job. The installation video is right on and that made set up for the job pretty straight forward. Jackstands(4), a couple of 8t bottle jacks, air impact wrench/sockets, torque wrench, combination wrenches, lead hammer, grease gun, anti seize and some cribbing and you will be able to get the job done. The kit and parts are so much more robust than the stock hardware that comes with the trailer and should be much better than what came stock. I will report back once I get some miles on the road and tell you what I think of how it pulls and handles the bumps! 357303

I just opened the box and was disappointed to see that everything was just thrown in the box. Just looking at it it looks like some of the threads are damaged from the way everything is packaged. It will be a while before I will be installing this product. I want to say that the service from etrailers was outstanding!! From fast shipping and great price I couldn't be happier with etrailer. 475693

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


After a year and 20,000 miles, this was one of the best upgrades in towing and ride on my 42' fifth wheel. It took out a lot of the small bumps that would open cabinet's and knock things over in the shelves. Another great advantage is the bronze bushings are greasable and do not squeak like the OEM plastic, the OEM bushings had around 3000 miles and we're already worn through, the bronze if kept greased will probably last the life of the trailer. 438995

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


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. 491247

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


I installed the E-Z Flex Dexter K71-652-00 suspension system which was an easy afternoon task. Everything went together without any problems and was quite simple. We traveled on our first short trip of 650 miles with the new system and was great. The 30' KZ travel trailer road smoother and seem to handle better. I really recommend this system up-grade to all stock suspension systems with plastic bushings and steel equalizer. 355038

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


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. 572609

Review from a similar Dexter Axle E-Z Flex in Trailer Leaf Spring Suspension


The EZ Flex suspension system is so much more robust that the parts that were removed. Installation is pretty straight forward, however when doing it make sure you have jacks and stands to do the job. I did one side at a time it was pretty easy and took about 1.5 hours on each, all done on the driveway. I will give a further update when the time comes along to take the trailer out. This has got to give the trailer greater stability when towing. Customer support from etrailer is top notch and answered all my questions before I purchased the system. Thanks etrailer for your support, shipping was quick so there was not much wait time. 527486

Do you have a question about this Trailer Leaf Spring Suspension?


  • How to Determine Which Dexter E-Z Flex Equalizer Kit is Correct for a Trailer
  • To determine which Dexter E-Z Flex suspension system you need for your trailer you will simply need to choose whether your trailer has tandem or triple axles, as well as the length of your current equalizers. For a tandem axle trailer we have part # K71-652-00 which is 5-5/8" long, and part # K71-653-00 which is 7-3/4" long. For a triple axle trailer we have part # K71-656-00 which is 5-5/8" long, and part # K71-657-00 which is 7-3/4" long. I have attached some installation and...

  • Recommended Equalizer Shocks For Triple Axle 4200 Cyclone Toy Hauler
  • For your triple axle on your 4200 Cyclone toy hauler, I recommend the E-Z Flex Triple Axle Suspension Kit with 7-3/4" Equalizers # K71-657-00. This system includes the wet bolts, metal bushings, and shackle straps. This system is also available with 5-5/8 inch equalizers # K71-656-00. Another great option to consider is the Equa-Flex Cushioned Equalizers w/ Bronze Bushings - Double Eye Springs - Triple Axle - 5K to 8K # LC279689. These are very similar with the metal bushings, but...

  • Measuring For Compatibility Of Dexter E-Z Flex Triple Suspension Kit
  • For the Dexter E-Flex suspension, you need to measure the metal equalizer that you will find in the hanger between axles. The spread between that equalizer's furthest holes center to center is the measurement that will tell you if you need the E-Z Flex Triple Suspension System Kit with 5-5/8" Equalizers # K71-656-00 or the 7-3/4 inch equalizer system # K71-657-00. For the # K71-656-00, you need axles that are 33 inches apart on center and the equalizer measurement needs to be between...

  • Determining Correct Suspension Kit for Triple Axle Trailer

  • Correct E-Z Flex Triple Axle Suspension Kit for 6,000 lb Axles
  • The correct E-Z Flex Triple Suspension System Kit for you will depend on the length of your current equalizers as well as your axle spacing. Since you have 6,000 lb axles I recommend first taking a look at the E-Z Flex System # K71-656-00, which is for 5-5/8" equalizers with 33" axle spacing on center. If your triple axle trailer has 7-3/4" equalizers and 35 inch axle spacing you would need E-Z Flex System # K71-657-00, although generally this is for 8,000 lb axles.

  • Recommended Equalizer, Leaf Spring, and Hardware for 2005 Weekend Warrior Suspension System Upgrade

This kit comes with all the equalizers and hardware you need. Then you will use the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 and I recommend upgrading your axle u-bolts to the # APUBR-9.

  • How Often Should Dexter EZ-Flex Equalizers Get Greased
  • I spoke to my contact at Dexter and he informed me that they recommend greasing the E-Z Flex equalizers every three months or 3,000 miles. I also attached a pretty helpful guide to how often trailer components should be maintained. For grease Dexter recommends wheel bearing grease. For that we recommend the red grease part # L11390. A shock kit would help your trailer and would work well with the EZ Flex system but since you said you have square axles we don't have a kit for that....

  • Which E-Z Flex Heavy Duty Rubber Suspension System Fits a 2007 Keystone Raptor 3814SS 5th Wheel
  • The 5-5/8 inch E-Z Flex Equalizer in part # K71-652-00, have a capacity of 3,000 pounds (6,000 total for the whole system). The 7-3/4 inch equalizers in the Triple Axle Kit, # K71-657-00, have a capacity of 4,000 pounds (16,000 pounds for the whole system). When I did a little research on your 2007 Keystone Raptor 3814, I found that it has a dry weight of 11,525 pounds.

  • Recommended Fix for Triple-Axle 5th Wheel Toy Hauler Surging & Bouncing
  • The 15,172-lb unloaded weight of the Forest River triple-axle toy hauler 395AMP is potentially getting pretty close to your Silverado 2500's towing limit by the time the trailer is loaded up, so the first thing I suggest is making sure the trailer is loaded in such a way that you have enough pin weight. Too little pin weight can lead to handling issues like sway and bounce. 5th wheel pin weight should be 20-25% of the gross trailer weight. When transporting several 4-wheelers, for example,...

This will mean a possible change in the length of your shackle straps. These are the proper width and are 4 leaf springs capable of a 2,000 lb capacity individually or 4,000 lbs per axle.
