Video Transcript for Dexter Axle Trailer Suspension - Leaf Spring Suspension - K71-652-00 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 K71-652-00 and for triple axle applications with part number K71-656-00. This is going to replace standard trailer equalizers and leaf spring suspensions. It is designed for 1 3/4" wide double eye leaf springs. This system's going to deliver nice, smoother towing when compared to traditional leaf spring suspensions. It's got this nice rubber core that isolates and absorbs damaging road shocks before they hit the trailer frame and the contents.

The rubber core's going to last a long time and won't be affected by the elements. It's a very simple installation. It does not require any welding, cutting or grinding of the trailer frame, and it's going to include all the hardware necessary for your installation. It's also going to come with detailed installation instructions. The system is made from a nice, durable steel construction. It's going to feature a protective finish to keep everything safe from the elements so you don't have to worry about rust or corrosion building up.

The system also offers multiple grease zerk fittings for easy maintenance, so you can see on all of the bolt heads as well as the actual equalizer components, we're going to have those zerk fittings. That's going to keep everything well-lubricated and quiet at all moving components, so that's a really nice design of the unit. This is a direct replacement for the Dexter standard equalizer 13-104, so if your equalizer has that number stamped on it, then this will work great for your trailer. If you can't find a stamped number or you have a different brand of equalizer, then you will want to take a few measurements to verify that this system will fit your application. For instance, your axle spacing on your trailer must be 33" apart on center, so from the center of one axle to the center of the other, you need a separation of 33". The distance between the lower bolt holes on this system, that's this one right here and this one right here, is going to flex between 5 1/4" and 6 1/4" and the bolt hole diameters are 9/16th of an inch on the system. If the spacing of the holes on your equalizer is between those measurements, then this will work for your trailer.

The shackle measurement, measuring from one hole to the other, center on center, is going to be 2 1/4" apart, and this is designed for axles that have a capacity up to 6000 pounds. Really nice design, very strong and durable design. I just want to go over what it's going to come with. It's going to come with these four bolts right here. They all have grease zerk fittings on them, and it's going to come with the brass bushings for those. These do have the splines on them, so it forces into the mounting location.

Then it's going to come with the nuts to get everything tightened and secured. These are going to be designed for the end of the leaf spring that does not connect to the equalizer. Then you're going to get your equalizers. Again, it is available for tandem axle applications and for triple axle applications. You're going to have your center bolt. This is going to connect to the center hanger, bushings already included there, and you're going to have the nut to get that tightened down as well. Again, that's going to have the splines on it also. You're going to get all of your necessary shackles. The bolts on those shackles are already pre-installed, so you don't have to worry about that. The other end of your leaf spring's going to connect right here. It's going to come with a brass bushing. I just went ahead and loosely installed it all so you can kind of get a good idea of how the unit's going to work. It's also going to come with all the necessary hardware to get all that tightened down. That's going to do it for today's look at the E-Z Flex Heavy-Duty Rubber Suspension System.

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

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

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

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

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

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

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

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


Comments

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.

etrailer processes failed. I ordered this product on a Wednesday, during the check out process, I purchased 2 day shipping so it should have arrived on Saturday. It arrived on Monday because etrailer doesn't include Saturday delivery on Saturday. I purchased the same part from a big online store on Thursday night and got it on Saturday for $20 more. Don't purchase anything from etrailer with 2 day shipping past Tuesday. Go with the 3 day shipping. Its the same delivery schedule and you save $18 on shipping. I will never use etrailer again! Go somewhere else! The device when on great and fit perfectly. The trailer already seems very stable. 399486

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

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

Excellent product, I bought these to replace the equalizers that came stock on a new 10,000 lb rated 2014 car hauler that is on the road every day . At the time we bought the equalizers from etrailer, the stock equalizers had already been replaced 3 times. 5 stars ......... well worth the money, easy installation, reduced maintenance would definitely recommend to anyone using a heavy duty trailer every day. 241219

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

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

Smooth ride

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

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

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



- K71-652-00
by:

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



- K71-652-00
by:

tightened the suspension up, smoother over the bumps. Love it....Installation is not that hard provided you have a good heavy jack and the right tools... installed the upgrade in about 2 hours, using air tools and a good floor jack.. 569105

This was an exact replacement for the old E-Z Flex system on my 2006 5th wheel. It was a perfect fit and easy to install. The instructions were very helpful also. We bought this rv used 4 years ago, but as far as I know the suspension I changed had been on there 12 years. I tried to grease the old system, but most of the zerks were too stopped up to take grease. It didn't look like it had ever been greased, and most of the bushings were worn badly. Even still that speaks for endurance, and that's what I need since wife and I are full time RVers. These are before and after pictures. The camper tracks better and rides much more smoothly. Thanks E trailer! 567823



- K71-652-00
by:

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

Check your springs and replace them if they have lost their arch... Adding the EZ Flex is the only way to go ! A greasable suspension is great ! 562385

Dexter EZ Flex and Wet Bolt kit arrived as scheduled. Excellent packaging. All items were in package as listed. Easy installation with several tools. Overall a great experience from guidance on selection (thanks Diana H) to full install. Ready for my first 2019 trip. 612668

Didn't think these would make that much of a difference but they did. Really cuts down on the trailer being rearranged before you arrive at the destination. I was considering getting the shock absorbers as well, but these do the trick. 607940



- K71-652-00
by:

I can honestly tell you I wouldn't be without it. The peace of mind alone made every cent a great investment. Prior to the installation, drawers and cabinet doors would rattle open, magnets came off the fridge, a picture came off the wall and anything not screwed down had a tendency to move around. I visit the same campground regularly, using the same route so I have a reasonable baseline from which to draw the following conclusion. You may wish to think it's my driving, but I assure you it's not. Since fitting the Dexter equalizer, and the wet bolt kits with the bronze bushes, the ride is noticeably improved. Everything stays put, the coach tracks dead straight and it's a real pleasure to pull. 604304

Bought this kit last year for a tandem axle car hauling trailer. The original equalizer and bushings were just wore out from normal use. The wear was creating lots of extra vibration and noise. Thought I would give this a try. I am beyond impressed. The trailer now tows and rides as good as one of my other trailers that has torsion suspension. Vibration from axle misalignment and rattles are gone! I am so impressed I have now purchased another kit for my 5th wheel camper. Have not had the 5th wheel out yet but my expectations are pretty high after the improvement I have experienced with the other trailer. Some would argue that since my camper has shocks this is redundant. My answer to that is, "shocks and springs have different jobs". Very easy to install. Only took 2.5 hours total for both sides. 600585

I have not used these dampening type equalizers before, but the idea seems good to me. I mostly purchased this kit for the ability to grease the pins in equalizer and in the spring shackles. The brass bushing are also and good upgrade over the nylon type bushings. Replacing a standard type dexter equalizer that has worn both the pins and egged the holes in the equalizer. 593759

I received what I order on time. However, the shipping box was a little worse for wear. The internal box and containers had split open spilling nuts and studs all over the place. Luckily none of the loose parts got outside of the shipping box. I'm not sure if you could ever pack a box that could withstand the odd occasional bad shipping experience. With that said, the ordering and phone support at etrailer was excellent. 541577

Fast shipping, easy install and overall ride quality is definitely better. I think this kit is a great buy for any camper. Lots of moving parts with a bunch of weight on the suspension. I was surprised to see the amount of wear and tear on the factory bolts and bushings. This kit comes with everything you need. The “wet” bolts I feel have the potential to be the saving grace on your suspension. 516751

Install was fairly easy. However my trailer has the "Correct Trac" system which is really large washers on the spring hangers. This made it so the wet bolts were to short. I ordered longer wet bolts and I will see if they will work 498492

  • The Morrydy CRE3000 is a similar setup to the EZ Flex setup so there wouldn't be any problem going from one to the other. It would just be a matter of picking out the correct setup based on the dimensions of your current equalizers. You are going to have to measure your current equalizers to find the correct one. The part # K71-653-00 is a replacement for a 7-3/4 inch equalizer and the part # K71-652-00 is a replacement for a 5-5/8 inch equalizer. You will need to measure the dimensions...

  • Recommended Shock Absorption for Keystone Montana 5th Wheel with Tandem Axles
  • Trailer suspension uses different components for the air systems than the frame mounted suspension you are looking at. For your tandem axle Keystone Montana, I recommend the Lippert Components Trailair by Center Point Air-Ride Suspension Upgrade - Tandem Axle # LC1565391 which will give you adjustable air pressure in the form of an equalizer for your leaf springs. If you want a trailer with air suspension, this is the way to go with adjustable air springs that can use manual valves or...

  • Recommended Trailer Suspension Enhancement on 2017 Grand Design 30 Travel Trailer
  • The E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 will fit any system just like an equalizer regardless of the bracket, so this will be a good upgrade to take some of the bounce out of your trailer as it will absorb that shock. The shocks will assist to absorb more and won't be mounted to the area where the hanger protrudes from the frame, so there shouldn't be any alignment issues. Another option is to use the Timbren Trailer Suspension...

  • Recommended Lippert Trailair by Center Point Air Ride Trailer Suspension for Jayco Pinnacle 36fbts
  • The Lippert Components Trailair by Center Point Air-Ride Suspension Upgrade - Tandem Axle # LC1565391 will give you the smoothest ride of any of our comparable suspension systems. It will give you an extra 2 inches of trailer rise, so your trailer would most likely not have any tire rub if you were to upgrade. Your current system is more comparable to the Dexter E-Z Flex # K71-652-00 or Lippert Equa-Flex which both use rubber springs to cushion the ride. These are all really good...

  • 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....

  • Recommended Cushioned Equalizers to Replace Dexter 13-10 Equalizers
  • The 13-10 equalizer is equivalent to the Triangular Equalizer for 1-3/4" Double-Eye Springs - 6-1/16" Long - 9/16" Center Hole # TREQ310. If you go with the Dexter E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 they will work very well but will lower your trailer by about 1 inch. The Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 3K to 6K # LC279687 will also work and will do the same.

  • Recommended Suspension Upgrade For Tandem Axle System On 2017 Coachmen Clipper 21FQ
  • For your suspension upgrade, I recommend the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 or the Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 3K to 6K # LC279687. The Dexter system uses a rubber bushing to help absorb shock and the Lippert system uses a similar rubber core. The benefit of the Dexter system is you can see the bushing so you can tell when it is worn and needs replacing. The benefit of the Lippert system...

  • Availability of Dexter E-Z Flex Suspension System For Trailer with 34 Inch Axle Spacing
  • All of the equalizer suspension enhancements I have for double-eye springs are designed to fit either 33 inch spacing ( # K71-652-00) or 35 inch spacing ( # K71-653-00) between axles. I do not offer any that are listed for a 34 inch axle center spacing.

  • Rubber Equalizer Troubleshooting on a 2008 Keystone 344J Everest 5th Wheel Trailer
  • I did some research and found that your trailer is rated at well over 14,000 lbs. so the correct replacement equalizers would be the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 7-3/4 inch Equalizers, item # K71-653-00. The part you mentioned, item # K71-652-00, is for up to 6,000 pound capacity trailers and would be too light for your Keystone Everest trailer. Depending on your gross trailer weight, loaded and ready to tow, the # K71-653-00 may also be too light for...
