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.

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: Clay M.05/02/2017
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.

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: 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: 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
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: 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: 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!
by: Larry11/21/2017
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 Leaf Spring Suspension
- How to Determine if the Dexter EZ Flex Triple Axle Suspension System Will Fit a 2009 CycloneThe Dexter EZ Flex suspension system # K71-657-00 will fit in place of equalizers that are 7-1/4 to 8-1/4 inches long. The length is measured from the center of one hole to the center of the other hole. Measure the length of your equalizers to determine if the kit will fit.
view full answer... - 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... - Dexter E-Z Flex Suspension Upgrade For Triple Axle Trailer With 13-126 Equalizers Yes, the Dexter E-Z Flex Suspension Kit # K71-657-00 is the correct kit to upgrade your triple axle trailer which currently utilizes the 13-126 equalizer. Both these are designed for axle spacings 35" apart.
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.
view full answer... - Will Dexter E-Z Flex Equalizers K71-657-00 Give Triple Axle Toy Hauler More Axle Travel?The Dexter E-Z Flex Suspension Kit # K71-657-00 will replace the current equalizers on your triple axle toy hauler as the front equalizer 13-126 you have means you have 35" axle spacing which is exactly what this kit was designed for. This kit will not give your axle extra travel but will instead absorb road shock and eliminate chucking giving you a much better ride. I included a video of the # K71-657-00 for you to take a look at.
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... - Shackles Not Aligning With Bolts On Dexter E-Z Flex Suspension KitIn regards to the Dexter E-Z Flex Suspension Kit like part # K71-657-00, I too ran into the same issue of the holes in the shackle not lining up with the bolts. This was a simple fix as all that was required was to simply use a hammer and hit the bolts in either directly to then re-align them to the shackles. I agree they should fit out of the box but it's a minor adjustment to make that should not take much time/effort.
view full answer... - Will E-Z Flex Triple Axle Suspension Kit With 7-3/4 Equalizers Fit 6,000lb Lippert AxleWith 8 inches center to center hole that's a good start as these will flex between 7-1/4 to 8-1/4 measurements however you also may make sure you have the 35" center axle to center axle spacing and have 9/16" bolt holes. The # K71-657-00 is a direct replacement for the Dexter Standard Equalizer 13-122 so these will be a fit.
view full answer... - 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.
view full answer... - How to Measure to Determine if E-Z Flex Triple Axle Suspension Kit # K71-657-00 will FitSince the left to right distance between your current equalizer holes is 8 and 7-1/4 inches the triple axle kit part # # K71-657-00 will fit since that's compatible with what this is designed to fit.
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.
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... - 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... - 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... - Which E-Z Flex Heavy Duty Rubber Suspension System Fits a 2007 Keystone Raptor 3814SS 5th WheelThe 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. If the existing equalizers have the same ratings as the E-Z Flex models, then they have a capacity of 12,000 pounds...
view full answer... - Will Dexter E-Z Flex Suspension Kit Fit a Triple Axle Weekend Warrior 5th Wheel The Dexter E-Z Flex Suspension Kit part # K71-656-00 is designed for a triple axle trailer with 33" axle spread which is the distance between the axles on center. I don't have a way to look up the axle spread for any one trailer but so long as you have what this kit designed for, 33" then it will be a great fit. The Dexter E-Z Flex Suspension Kit part #K71-657-00 is the same kit as the above but for a 35" axle spread. If you have a different axle spread please just let me know what that...
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... - Why Do the Dexter E-Z Flex Equalizers Turn DownI spoke to my contact at Dexter Axle and they informed me that you may have the incorrect kit. There are currently two different E-Z Flex Triple Axle Suspension Kits for triple axle trailers which will depend on axle spacing. For example, if your axles are spaced 33" apart then you will want to use part # K71-656-00 but if your axles are 35" apart then you will want to use part # K71-657-00. It looks like you have the part # K71-657-00 therefore your axles should be 35" apart center to...

- Which Dexter EZ Flex Kit Fits Triple Axle Trailer with 35 inch Axle Spacing Yes the Dexter E-Z Flex Suspension Kit # K71-657-00 definitely is a fit for your trailer based on the axle spacing and the shackle dimensions you listed.
view full answer... - Determining Correct Suspension Kit for Triple Axle Trailer The Dexter E-Z Flex Triple Axle Suspension Kit # K71-657-00 referenced in your question is designed for triple axle trailers and includes equalizers that measure 7-3/4 inches long. If your Weekend Warrior has 3 axles and the equalizer length matches your existing set, this should work great. The shackles included with this kit have an overall length of 3-3/4 inches and a distance between bolt holes of 2-1/4 inches (center to center). If the 2-5/8 inch shackle measurement you provided...
view full answer... - Dexter Ez Flex Kit for Fitting 2020 Attitude 5th Wheel with Triple AxleThe Dexter EZ Flex kits are the most popular and we recommend them highly. I do not know the axle capacity of your trailer but we have the 6k axle kit part # K71-657-00 as well as the 8k kit part # K7656-00 which would work well as long as you can verify the capacity of your axles.
view full answer... - 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... - Determining Which Dexter E-Z Flex Suspension Kit Will Fit a Snowmobile Trailer With Axles Spread 36"Due to the various spring lengths and equalizers which could be on your trailer it is best to measure the length of your current equalizer from the front to the rear mounting holes on center. The Dexter E-Z Flex Suspension Kit # K71-652-00 has the holes spread 5-3/4" while the Kit # K71-653-00 spaces the holes 7-3/4" on center. You will want to select the kit with the equalizer closest to your size. You do not need the distances to be exact as the included shackle straps allow for the play...
view full answer... - Which EZ Flex Trailer Suspension Kit Fits a Triple Axle TrailerThe E-Z Flex Heavy Duty Rubber Suspension System # K71-652-00 is designed for a tandem axle trailer. For a triple axle trailer you will need either # K71-657-00 with 7-3/4 inch long equalizers or # K71-656-00 with 5-5/8 inch equalizers. You would not use just one set on one axle of a triple axle trailer because it would create a poor ride on the trailer and could increase the stress on the other suspension parts. In your picture it appears that one of the equalizers is different causing...
