Have not installed them yet. They seem to be much better quality than the Equa-flex that came on the 5th wheel. Very happy with E-TRAILER and their knowledgeable staff.
by: Sean04/03/2024
Sent wrong product have welder scheduled based on package arrival e trailer only willing to ship out correct package with regular shipping. No interest in making the mistake right. I'm no longer interested in doing business with company with such low regard for customers and their situation.
by: Sean 03/07/2024
Great quality nice to have grease fittings it is a process getting to all the fittings though when you do grease it.
by: William 10/30/2023
The shipping was fast and the kit was complete. Installation was simple and fairly easy. Yes it did take a full dayto do the installation, but the end result was worth it. The coach rides smoother with less thumping. There is a noticeably less porpoise action when hitting road bumps. There is less side slip when passing other large vehicles since the suspension is stiffer. Seems to hold the line straighter.

I have not been home yet to inspect the merchandise in the package, but this is how the package was delivered to my house this morning.

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

All together this is a great upgrade and the components themselves fit well and as described. Only 3 stars on the review though and here's why.
First, the items were very poorly packaged and several of the linkage bolts had protruded through the packaging and were damaged. About an extra hour and a few specialty tools were required to file and re-tap the threads, luckily I have easy access to the tools.
Second, the kit contained too many center equalizer mount bolts and too few outer wet bolts. I was again lucky that this didn't cause a big set back as I had kept extra wet bolts from a past trailer repair and had them on hand.
Although having nothing to due with the kit itself but due to the design of the front equalizer, I encountered clearance issues on the middle hangers. The hangers on my 09 WW LE3305 have gussets welded inside of them from the factory which had to be clearance to clear the zerk fittings. I also had to modify the hanger for the front equalizer to allow clearance when mounting the hanger in the upper hole, I believe it may have been okay in the lower hole without modification.
Overall I am happy with the product and the excellent service that etrailer provides.

great products.

I installed this on a 2008 KZ Sportsman New Vision 40P Toy Hauler. Triple axle. We noticed a difference in the bounce on our trailer right away. Rear part of my trailer always gets bounced more than the rest of the trailer. Not so much now. Yes I would recommend this suspension upgrade especially on triple axle trailers. When I removed my old equalizers the holes were oblong instead of round where they bolted to the frame.
by: John C08/24/2017
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.
by: Ray 08/28/2022
It’s the best set up in my opinion if you don’t have slipper springs. E trailer came Thur again, only minor delays in shipping which was beyond anybody ‘s control. Price was way cheaper than anyone else, period. No, there no paid endorsement here, they earned it.
by: Marc11/01/2017
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.
by: Rick11/17/2021
This kit was easy to install and is very high quality. There were a few small parts missing but I called and received the parts within a couple of days. Excellent customer service

Works perfectly. The quality is 10 times better than the junk it replaced.
by: Robert M. 10/10/2018
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!

Happy with it made a difference in how trailer handles. Did have a few problems with installing but that was due to me and not the product.

See what our Experts say about this Dexter Trailer Suspension Parts
- Correct E-Z Flex Triple Axle Suspension Kit for 6,000 lb AxlesThe 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.
view full answer... - Which Dexter EZ Flex Triple Axle Equalizer Kit Comes with Equalizers that are 7-3/4 inches WideThe Dexter EZ Flex kit part # K71-657-00 that you referenced is a triple axle equalizer kit that comes with cushioned equalizers that are 7-3/4 inches wide from bolt hole center to bolt hole center. You may have ordered the # K71-656-00 instead as it comes with equalizers that are 5-5/8 inches wide instead. Based on what you said you need the correct kit is the part # K71-657-00.
view full answer... - Dexter E-Z Flex Suspension Kit For 2008 Jayco Triple Axle 5TH Wheel CamperThe Dexter E-Z Flex Suspension Kit # K71-657-00 is a universal suspension kit but you will need to confirm a few measurements on your 2008 Jayco 5th Wheel to ensure a proper fit. First this kit is only designed to work with double eye leaf springs that are 1-3/4" wide. The equalizers in this kit are designed to replace equalizers that are 7-3/4" wide for the short equalizer and 8-3/8" wide on the long equalizer. They are 2-7/8" tall and use shackle straps that are 2-1/4" from hole center...
view full answer... - Cushioned Equalizer Replacement Kit for 2004 Weekend Warrier with Triple Axle SetupThanks for getting me the width of your current equalizers. Since they are 7-3/4 inches the part # K71-657-00 is a great solution that includes cushioned equalizers that fit as well as shackles and everything else needed to install. This will improve the ride quality of your trailer suspension noticeably. I attached an install video for this for you to check out as well.
view full answer... - Height of Cushioned Equalizers Included With Dexter Triple Axle K71-657-00 E-Z Flex Suspension KitThe cushioned equalizers included with the # K71-657-00 E-Z Flex Suspension Upgrade Kit are 2-7/8 inches tall, which would lower your trailer by a half inch, which will only lower your ride height by small amount. The kit includes the shackles and related hardware.

- What Type Of Nuts Are Used With the Dexter E-Z Flex Suspension KitsThe E-Z Flex Triple Axle Suspension Kit part # K71-657-00 comes with both flange nuts part # 006-092-01 and lock nuts part # 006-007-01. The flange nuts which are essentially a nut that has an integrated washer that reduces the chance of loosening because the clamping force is more evenly distributed around the nut are used on all of the wet bolts whereas the lock nuts are used on the standard bolts. The wet bolts are used to connect the leaf springs to the equalizers whereas the standard...
view full answer... - Suggested Equalizer Upgrade Kit for Triple 8,000 Pound Axles with 33 Inches of SpacingAs the Dexter # K71-657-00 is rated for 35 inches of axle spacing, I do not suggest using it. However, we do have a MORryde system that will work with your spacing. The MORryde Shock Absorbing Suspension Equalizers for Triple Axle Trailers w/ 33" Wheelbase - 8K # MR59ZR is specifically designed to be used with 33 inches of axle spacing and 8,000 pound axles. The MORryde Suspension Upgrade Kit # MR86ZR would then complete this kit and get you up and running.
view full answer... - Recommended Fix for Triple-Axle 5th Wheel Toy Hauler Surging & BouncingThe 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,...

- Which Dexter EZ Flex Kit for 2009 Weekend Warrior Triple AxleFor a triple axle trailer with 6k rated axles the correct Dexter EZ Flex is the part # K71-656-00. The # K71-657-00 would be for 8k axles. I attached an install video for this kit for you to check out as well.
view full answer... - Instructions to Use with Dexter EZ Flex Equalizer Kit for Triple Axle TrailerWhile we don't have a set of printed instructions I can show you for the Dexter EZ Flex part # K71-657-00 that you referenced we do have install videos that we shot when we installed this kit on two trailers that I attached to this page.

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. I have attached the dimensions of this spring to help. The capacity is more important than the number of leafs, so you want to get as close to your measurements as possible...

- Converting Triple Axle Trailer From Slipper Springs to Double Eye SpringsYou will need to weld on new spring hangers to convert your triple axle trailer from slipper springs to double-eye leaf springs. The linked page shows you all hangers. Select hangers of the same height as the current ones to keep the trailer's stance as it is now or taller ones if you want to raise its height. For selecting cushioned equalizers you will want to match the hole spacing dimensions to your current equalizers. Please refer to the linked page showing cushioned triple-axle kits...
view full answer... - Correct E-Z Flex Suspension System for Triple Axle Trailer with 6,000 Pound AxlesIf your trailer does have 6,000 pound axle it's likely you'll need the # K71-656-00 E-Z Flex Suspension System. The equalizers are 5-5/8 inches long between the bolt holes center on center. The other kit we carry is # K71-657-00 which is generally for 8,000 pound axles has equalizers that measure 7-3/4 inches long.
view full answer... - Recommended Suspension Upgrade for a Keystone Carbon 417The Keystone Carbon 417 should have a 35" axle spread which can be confirmed by measuring from the center of each axle. In which case, we have options from both Dexter and MORryde. The MORryde Rubber Equalizers for Triple Axle Trailers part # MR39ZR and Dexter E-Z Flex Suspension Kit part # K71-657-00 are both great choices. I recommend Dexter as it comes with the shackle straps and wet bolts so it's more of a complete kit and the shackle straps are much ticker than normal for increase rigidity.

- Are Different Length Spring Equalizers Normal on a Triple Axle Trailer?I spoke with a representative of Dexter Axle, who told me that it is perfectly normal for the front and rear equalizers to be different lengths. I've added a link which shows you each of our triple axle equalizers, as well as a a link to a help article which you may find useful.
view full answer... - Recommended Dexter E-Z Flex Suspension Kit for a 2020 Keystone Voltage w/ 35” Triple Axle Spacing Since your 2020 Keystone Voltage trailer has three 7,000 lbs axles that have 35" spacing you will want the Dexter E-Z Flex Suspension Kit item # K71-657-00. The next size down is for 6,000 lbs axles. The 8,000 lbs kit will work great with your trailer. I have linked an installation video below.
view full answer... - Triple Axle Suspension Kit With Greaseable Wet Bolts and Equalizers Yes, we do have the Dexter Heavy-Duty Suspension Kit for Triple-Axle Trailers # K71-360-00. This kit is designed for an axle spacing of 33" with its curved equalizers. We also have the Dexter E-Z Flex Suspension Kit # K71-656-00 which is also for an axle spacing of 33" if you want to go with a cushioned equalizer. This kit is for axles weighing up to 6,000lbs each. The 8,000LB Kit # K71-657-00 has longer equalizers designed for a 35" axle spacing.
view full answer... - EZ Flex Equalizer Kit for Triple Axle Setup that has 7-3/4 inch Long EqualizersSince your current equalizers are 7-3/4 inches the EZ Flex kit part # K71-657-00 that you referenced would fit and work well as a replacement. The ride height would not be significantly changed either. While you do have a unique looking suspension hanger on your trailer this would easily fit the same way. I attached an install video for this kit for you to check out as well.

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 # e94SR and I recommend upgrading your axle u-bolts to the # APUBR-9. You will use the following quantities: 1-E-Z Flex Kit 6-Leaf Springs 3-U-bolt Kits This update...

- Will E-Z Flex Triple Axle Suspension Kit Fit a 2002 Alfa Toyhouse Triple Axel TrailerThe E-Z Flex suspension kit # K71-657-00 is designed to replace triple axle systems that have 7-3/4 inch long equalizers. Measure the equalizer length on your current set up (from the center of one eye to the center of the other eye) to determine if this kit will fit your trailer. There are 3 different hanger kits associated with the PR6 spring and triple axle trailers. Two of them have 7-3/4 inch long equalizers and one uses 8 inch long equalizers so there is a good chance that K71-657-00.

These are so much better than the Equaflex that came on the trailer. Much better quality and heavier duty. Installation was pretty easy with the right tools.
