Features to know about

Smoother Ride Over Rough Roads: Rubber Core Absorbs Road Shock

Bumpy and uneven roads can make towing feel harsh. The E-Z Flex equalizer uses an internal rubber core that cushions the suspension, absorbing road shock and cutting down on the back-and-forth movement known as chucking. It smooths out the ride so your trailer tracks steady and your cargo stays put, even when the pavement isn’t perfect.

Direct Replacement Without Changing Ride Height: Works With Existing Hangers

When it’s time to swap out worn parts, this equalizer fits right in. It’s made as a direct replacement for E-Z Flex suspension kits K71-653-00, K71-657-00, and K71-655-00, and it installs using your existing hangers without altering the trailer’s ride height. The geometry and bolt spacing are made to match so everything lines up cleanly.

Built to Last: Sturdy Steel Construction With Corrosion-Resistant Bronze Finish

Suspension parts take a beating, so durability matters. This equalizer is built from strong steel for long-term reliability and is finished in bronze to resist corrosion from water and road grime. The solid build keeps your suspension in control mile after mile.

Sized Right for Reliable Performance: 7-3/4" Center-to-Center Design

Getting the right fit keeps your suspension geometry correct. This equalizer measures 7-3/4" between the side bolt holes (center on center), with 3-7/8" between the hanger bolt hole and side bolt hole, and 2-7/8" from the side bolt hole to the hanger bolt hole. It’s designed for triple-axle setups with 1-3/4" wide double-eye springs and 9/16" bolt holes, giving you a solid connection that moves smoothly through each cycle.

Dependable Suspension Upgrade Backed by Dexter

Dexter’s E-Z Flex equalizer is a proven replacement choice when restoring ride quality and stability. It keeps your suspension functioning as intended and comes with a 5-year limited warranty for extra confidence out on the road.

@Ivan Wow, that seriously means a lot, thank you for sticking with us over the years! We couldn't do it without you. I’m really glad everything from the RV AC to the steps and trailer parts has held up well for you even after a full year. We’ll happily take that six-star rating anytime! If you ever need anything down the road, we’ve got your back. What kind of RV do you have? Any big summer plans?

Way stronger than the original version!

Joshua T. Helped me pick these items to get my old car hauler up to par. This is a very easy install to do took 2 hours start to finish. Prior to this I had the typical popping noise from equalizers and shackles being worn. Decided to try these Dexter EZ Flex equalizers. Man what a difference in ride quality. Huge improvement. Highly recommend this paired with the new bushings and wet bolt kit. Should last for years now.

The parts were an exact replacement part and while ii is a bit of work to install them it is a straight forward diy project to restore the suspension to its original condition.

Sorry about that Sam. Not quite sure how we managed that as they are even a different color. I see our Customer Service team sent out a pre-paid return label for this and you will be getting a full credit back for them. Was there anything else we can help with in the mean time?

Have not installed yet but everything looks good and was received within a few days. Thank you E trailer

Best built equalizer I have seen. Center pivot is about an inch in diameter and has tight bronze bushings. Rubber is clearly visible for inspection. I replaced my Equa-Flex with this equalizer.
by:
Heavy duty. Got about 10 years out the prior pair.
by:
Parts arrived on time! You bid a great job of getting them to me in this time when most everything is shut down . I have been buying parts from etrailer for five years + and have gotten good advice and quality parts!!
by:
I will not be installing this part for a few weeks so I can’t comment on the part, however I can comment on the packaging. This is the second order I have made in the last few months the other being a new pin box. This part arrived with the box busted open in a few places exactly like the last order. The parts were allowed to just float around in the box as there was only a small piece of paper filling in any gaps.
by:
etrailer had the best price I could find. And shipping was faster than other online retailers, That's FAST.
by:
These folks are great. Will definitely use again if I need RV parts. Thanks for your prompt attention.
by:
Gracias si todo funciona bien
by:
Great phone service, arrived on time, perfect fit.
by:
Justice promise Natalie made sure that the part was delivered on Wednesday and that’s today. That gives us time to do the install before we head out for our Christmas RV trip.

They help.

  • Looking For Replacement Equalizers And Shackles For Old Tandem Axle Horse Trailer
    Hello Darrell, thanks for reaching out. The EQ-E1 equalizer is 7-3/4" long and 2-7/8" tall, and the Dexter E-Z Flex Equalizer # K71-655-00 is virtually identical in size so this will be a great option for an upgraded equalizer. As far as the shackle kit, I recommend the MORryde Suspension Upgrade Kits since they come with HD shackles, bronze bushings and wet bolts. I will need to know the length of your current shackles measured center hole to center hole. The MORryde kits come with either...

  • Replacement Equalizer and Wet Bolt Kit w/ 2-1/4" Shackle Straps for a 13-144 Equalizer
    Thanks for the information John! To replace your 13-144 equalizers, I recommend the Dexter E-Z Flex Suspension Kit item # K71-653-00. Aside from the cracked rubber these will be identical equalizers to your current ones. The Dexter E-Z Flex Suspension Kit item # K71-653-00 also includes heavy duty 2-1/4" long shackle straps, wet bolts, and bronze bushings. This kit does work with the LCI Correct Track system. so you won't have to worry about any compatibility issues. The Replacement...

  • Do You Carry the Center Rubber Bushing for the Dexter E-Z Flex Equalizers with 13-143 on Them?
    Hello Daryl, The reason you’re having trouble locating a replacement is because Dexter does not offer a separate rubber bushing for the 13-143 equalizer, you’ll need to replace the entire unit. If the others are showing signs of wear as well, I recommend replacing the full set so you maintain even wear and performance across your suspension. If you just need a single replacement, the part number is # 013-144-03. If you're ready to replace all three for a triple axle setup, the full kit...

  • Replacement Leaf Springs, Cushioned Equalizers, and Axle Bolts for 2020 Grand Design Reflection
    Hey Paul, between the three part numbers you mentioned of # E34SR, # K71-653-00 and # APUBR-8 you would have all of the needed hardware to install the cushioned equalizers. You wouldn't need anything else.

  • Replacement EZ Flex Equalizer Kit for Tandem Axle Trailer with 7k Axles
    Based on the current condition of your Dexter EZ Flex kit it's going to be the best solution to replace the entire kit with the part # K71-653-00. This comes with the two new equalizers you need, all new shackle straps, new bolts, nuts, and bushings. This kit includes shackles that are much thicker than what you have now which will be much more heavy duty and last a lot longer. Since the shackles are what wore out the rest of your system too this will give the entire setup a much more heavy...

    The number you provided, "7753400" is a patent number which corelates to the Equalizer for E-Z Flex Suspension part # 013-144-03. This is for a single equalizer but if you need the entire kit it's the Dexter E-Z Flex Suspension Kit part # K71-653-00.

  • Do I Need Shorter Straps or Taller Equalizer for My Trailer with Double Eye Leaf Springs
    Considering all that has been done so far, I think the first step I would take here is to go with the shorter shackle straps. If you're still getting contact with the trailer frame, I would then take a look at upgrading to a taller equalizer like the Dexter EZ-Flex # 013-144-03 or you could have the front and rear hangers cut off and welded back on 1/2" further from each other in each direction. I've linked our selection of shackle straps to this question so you can find what you're looking...

  • Does Dexter E-Z Flex Suspension Kit Have a Torque Spec
    According to the Dexter Axle instructions, the bolts that are used to install the E-Z Flex Equalizer for 1-3/4" Double Eye Springs # 013-144-03 should be torqued in the range of 30 - 50 ft-lbs (see attached cutout). Attached is an installation video of the Dexter E-Z Flex Suspension Kit # K71-653-00 which the part you asked about is a replacement for.

  • Replacement for Dexter E-Z Flex Equalizers 13-144
    Hi Robert; thanks for providing that information and the picture. The rubber isn't something that can be replaced so you will need to swap out the whole equalizer. The correct part is the Replacement Equalizer for E-Z Flex Suspension Kits # 013-144-03. These will be identical to your current 13-144 equalizers (aside from the cracked rubber).

  • How To Reduce Chucking On a 5th Wheel Camper Using a Goose Neck Hitch
    There could be a few things that cause chucking. If extra weight has been added to the front or back of the trailer or traveling with any of your tanks full. In my experience I have not found that adding or reducing the pressure in your tires will change the chucking effect What I have found that reduces the chucking effect is replacing the equalizers on the trailer. Chucking is usually caused by the two axles working against each other. For instance when you apply the brakes on the...

  • Determining Which Equalizers, Shackles, and Wet Bolts Fit Trailer W/ Squeaking Suspension
    I would be happy to walk you through how to determine which replacement components you will need, but you will need to take a few measurements of the components on your trailer. First the # 013-144-03 you were looking at measures 7-3/4" from center to center of the horizontal mounting holes as shown in the included diagram. As long as this matches your current equalizers this would be a great replacement option. Moving on to the shackles you will need to measure center to center of the...

    To find the correct E-Z Flex Equalizer, you will need to take off your current ones and measure the distance from the center of the one end hole to the center of the other.
