Video of E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to show you how to install the Dexter Axle E-Z Flex Heavy Duty Rubber Suspension System, part number K71-652-00. Here's what it's going to look like when we get it installed. As you can see we've replaced that solid steel equalizer with one that's got a really nice heavy duty rubber bumper in here. That's going to help to absorb a lot of the shock that we're going to feel going into the frame of our camper, and then up into the contents that we've got inside. This also helps to reduce any noise that we get from our suspension system. Let's face it, they're pretty noisy all the time, but with the brass bushings that we're now going to have in our spring eyes, and our lubrication points at each of our bolt, we're really going to be able to get this thing nice and quiet while we're headed down the road. This is going to include all the hardware that we need to do our tandem or triple-axle trailers, whatever combo you need.
As you can see, we've got our replacement bolts, and also shackles on each side, which are much heavier duty than the ones that we've had originally. Here you can see our factory equipped equalizer. You can see both of our springs are going to come up though the shackles, and they connect to that. This is going to keep equal spacing, and it also gives us a little bit of a pivot point back and forth here on this main bolt here. These do a great job of keeping the axles separate, keeping everything moving down the road.
They can be a bit noisy, and also they offer no shock absorption. Let's get these taken off. We're going to remove this bolt, this bolt, and this bolt. We can get our new ones in place. Now it's time to knock our old bushings out of our ends of our spring, or spring eye here. We're going to be replacing them with our new brass bushings.
You can see they're going to sit right in there. We'll do that for both of our spring eyes here. We'll also pull our front most bolt here. You can see our old bolts will work great as a driver to where we can drive those in if necessary. We'll bring that back up, and we're going to bring in one of our new bolts. As you can see, these are going to have a grease zerk in the end, and a small outlet there.
It's going to allow us to grease our pivot points here, and keep everything running nice and smooth, and nice and quiet. Then we'll thread one of our locking nuts onto the back side there, and just leave it loosely installed for now. We'll go up and take care of the front spring now. We can bring our new equalizers in, slide that in, and here we're going to use one of our silver bolts. On the back of that it's going to be one of our gold lock nuts. We can slide in one of our shackles at the bolts, they're already going to be there. Then we'll take our shackle for our other side, and that's going to slide on, and then put a lock nut on the backside. We've got that secure, let's get our other one taken care of. We'll slide our other side through now. You may have to, like we did here, drop one of your bolts, either the back or the front. We dropped this one out to give us just a little bit of room to drop the axle enough to get it lined up. Then, of course, that backing plate goes on, and then two more of our silver locking nuts. Now it's time to go through and secure all of our hardware. We'll go through and get all of our hardware torqued down. The torque specs you can find in your instructions. We'll also take care of our center bolt there. We have our fittings lubricated up here, that way we'll have a nice, smooth, quiet running system. We're going to clean up our grease zerks there, get our tires back on, and just going to do the exact same thing over on the other side of the trailer. With everything torqued down to specification that's going to complete our installation of the Dexter Axle E-Z Flex Heavy Duty Rubber Suspension System, part number K71-652-00. .

Great product!!! I installed the the kit on a travel trailer just before a 7500 mile trip around the country!!!! Installation was straight forward and the product preforms great !!!!! 478451
Product is preforming great no problems so far !! Would definitely recommend this upgrade!!!
Ronnie - 02/25/2019The 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
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
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'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
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
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
Larry M - 10/04/2016Replacement 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
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 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.
Doug W - 07/07/2017The 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
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
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 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
Installed ez flex on our rv
-- comment by: Jeff - 04/30/2018I 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
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
The people were great, thank you for understanding my situation and going above the norm to get my order to me. 554350
This product exceeded my expectations, with a few hand tools an electric impact wrench and an alignment pry bar, installation was a breeze. Did one side in an hour tonight, will do other tomorrow night 246409
Still going strong
ALFRED Q - 04/21/2017I 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
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
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
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
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 like the equalizers, no more squeeking, coupled with the heavier leaf springs i have a better ride. Only one of the four doors/drawers pops open during travel now. I did have problems installing them, the axle was difficult to get back in place on one side, if I had jacked up the whole trailer (all four wheels off the ground) it would have been a lot easier, live and learn. Oh, had my 18 year old granddaughter and two of her girlfriends do almost all of the work as I had minor surgery on my shoulder a week before we did the change out, they wanted to do a 5 day campout with the trailer so the broken leaf spring had to be replaced. Very satisfied with them, the girls work and the equalizers. 654648
Where good.came in on time.ez install old ones where worn out.I have a 32ft Toy hauler.Toes a lot better now.I still have chucking.I have In stalled air ride pin box to get most of chucking out.Toes good now.I would recommend reflex. 642633
Awesome product two times thicker than the original parts. One less thing to think about when we go down the road 636027
Very noticeable difference if tire pressure on trailer and tow vehicle are proper -- not over inflated. Relatively inexpensive upgrade for rough ride. Good service 634407
My trailer was due for some maintenance cuz everytime I was returned when the axles twist there's a lot of popping crack on going on this is when you know you need to change out the bushings and shackles. But with these pins you can keep the pins greased. I have 6540 lbs inside trailer all the time. So now the trailer rides a little. Plus the it quiet things up when I now turn. 633944
Not sure why RV trailers all seem to come with a cheap suspension with no way to grease moving parts. We replaced the stock suspension items with this Dexter after market kit prior to embarking upon a 12,000+ mile RV trip through Canada. The axles are Dexter as well, but they make these kits for other brands I believe. Now with grease fittings at all moving suspension points, we can provide proper maintenance. 629161
Huge improvement, 32 foot holiday rambler fifth wheel towed much better. Eliminated noise coming from the axles. Reduced the vibration to the hitch on the truck tremendously. Gives me peace of mind knowing I can lube the shackle bolts. 623231
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
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
Parts look good in box...have used them before and was satisfied then as well so not expecting any different outcome. 595524
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
ordered on tuesday. on my step thursday afternoon. 589431
ride seems better, old plastic bushings were shot would say if you are going to do anything other then leave your rv parked its needed upgrade. hardest part of install was getting the trailor safely supported 584579
Product was shipped fast and arrived in good condition. Looking forward to installing the EZ flex system. This suspension system is well over twice the size of original factory system and should last a lifetime. 577212
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
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
Trailer pulls smoother and way quieter than ever! Definitely recommend this upgrade. 561204
etrailer made this whole process as easy as possible. Chose the 3 to 5 day shipping got it in three days. The package was intact all the parts were there and the instructions were very good. I even went on the products website and checked out their installation videos. Those were also very helpful. As usual etrailer took good care of me. To steal a quote “I’ll be back” 546367
High quality parts. A real nice upgrade for any camping trailer. Lubrication ability is a real nice feature. No more groans and squeaks. 544702
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
EZ Flex was an EZ install. Paired with Moryde crossbar system is a big improvement over stock to suspension. etrailer rocks!! 538915
The Heavy Duty Rubber Suspension System is very good it make pulling my trailer a lot better, it has help the way my trailer go down the road for the better. The hrandest part was waiting for the part to get to me ,they when in reel E-Z . if I get any other trailer I'm going to get a set to go on the trailer . Thank You for all that you done to help me get the right parts. 528940
Product was delivered on time and all parts in the box. Install took about 3.5 hours. I put this product on my 26 foot travel trailer, greatly improved the smooth ride and eliminated a lot of road noise. 521245
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
