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.

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.



by:

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:

Great quality nice to have grease fittings it is a process getting to all the fittings though when you do grease it.



by:

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.



by:

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



by:

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.



by:

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.



by:

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:

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:

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:

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:

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:

Good price & service



by:

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:

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.



by:

Product is very robust. It arrived very quickly-I was surprised. All parts were present and instructions, even for me, were clear and adequate.etrailer you're awesome!

So far it's working great. The ride is much smoother.

  • 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.

  • Parts to Update Suspensions on 2007 Venture Triple Axle Boat Trailer
    The Dexter Heavy-Duty Suspension Kit # K71-359-00 you looked at would be a great solution for a replacement. You will need a quantity of two since you have a triple axle trailer. You will also have a couple spare bolts leftover should you need them in the future. I would piece a kit together to eliminate the extra but the equalizers aren't available separately. It comes with the heavy duty equalizers with grease zerks, wet bolts, and heavy duty shackle straps. You could also go with an...

  • 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. The...

  • 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 Suspension Kit and Leaf Springs With 34 Inches Between U-Bolts
    Based on the measurements you have given, the correct kit would be the # K71-657-00 Dexter E-Z Flex Suspension Kit - Double-Eye Springs - Triple Axle - 8,000 lbs. You want to use the short equalizers. The hangers you have are designed for the 7-3/4" short version. It is critical because if you use the wrong size equalizer the springs will not compress and operate correctly. It would move the shackles into a horizontal position which would not allow the suspension to cycle. It should look...

  • Correct E-Z Flex Suspension System for Triple Axle Trailer with 6,000 Pound Axles
    If 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.

  • 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.

  • 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...

  • Why Do the Dexter E-Z Flex Equalizers Turn Down
    I 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...

  • Can Dexter EZ Flex Trailer Suspension be Used to Fix a Tilted Equalizer
    The 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.

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 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.

    With 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.

  • Suggested Equalizer Upgrade Kit for Triple 8,000 Pound Axles with 33 Inches of Spacing
    As 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.

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.
