Features to know about

Smooths Out the Rough Stuff: Rubber Core Takes the Shock

Rough roads and potholes don’t have to shake your trailer apart. These E-Z Flex equalizers use a built-in rubber core that cushions the suspension and absorbs road shock. It helps cut down on the back-and-forth chucking that can wear on your gear and your nerves. The result is a smoother ride that keeps things inside from bouncing around.

Built Strong to Last: Heavy-Duty Steel with Bronze Finish

Standard cast equalizers can crack or wear out over time, but these are built from strong steel with a bronze finish that resists corrosion. They’re made to handle up to 8,000 lbs of axle capacity, so they’re right at home under heavy loads and long hauls. You can count on them to hold up and keep your suspension working the way it should.

Keeps Your Setup Aligned: Precise 7-3/4" Center-to-Center Design

Suspension geometry matters, and these equalizers are dialed in for tandem-axle setups. The distance between the outer shackle bolt holes measures exactly 7-3/4" center to center, with a 3-7/8" spacing to the hanger bolt hole. That means everything lines up cleanly, keeps your ride level, and maintains proper axle spacing at 35".

Straightforward Upgrade: Ready-to-Install with Hardware Included

Swapping out worn equalizers doesn’t need to be complicated. This set includes two cushioned equalizers along with the mounting bolts and locknuts you need to get them installed. Once they’re in place, you’ll have a solid, shock-absorbing suspension setup that makes every mile feel smoother and more controlled.

These are are direct replacement for the stock equalizers on my Dexter D44 4400lbs axles. They were very easy to install and have done a great job smoothing out the ride of the trailer. They are a lot heavier duty than the stock equalizer. So far I have been very impressed. If they last for a number of years I will be very happy

After a year these are still working great. They have done a lot to smooth out the trailers ride on the terrible roads.

An excellent product from Dexter and etrailer. This definitely smooths out the ride of your trailer and benefits you, your tow vehicle, and your cargo. Online ordering was easy and shipping was fast. Thanks etrailer!
by:
This is a very pleasant surprise brought on by some very high quality, well-engineered, American made, and high-tech upgrade solution to a problem serious travel trailer users across the country experience often. I believe this combined with my axle upgrade will take this problem off the table for years to come. The manufacturers should make these a standard.

Exact replacement parts for Heartland Bighorn trailer and at the lowest price around. Thanks once again, Repeat customer.

Excellent service from Alex helping me order, got them installed on my 7x12 tandem axel mobile grooming trailer.. I already purchased upgraded shackles extra thick, just had everything installed, looks great and the ride is smoother !

I ordered the K71-655-00 which is for a trailer with 35” axle spread after a local trailer repair business up sold me the EZ Flex system, but put on parts for a 33” axle spread. Right at two years it started to rip the leaf spring mounts in half from the frame. After much research, I discovered their error and so far with the correct piece in place everything is happy again.

Great product easy to install.I have the rubber suspension for the 8000lb axel. Just make sure the spring bolts grease holes are facing the front are rear of the T. T. Before you seat the bolts put grease from the grease gun to make sure the grease will ease flow into the spring bushing and out side of the spring. Have not tried it yet.

Haven't installed them yet, but E-trailer/Carol C. was extremely helpful in finding the correct size and capacity equalizer for my trailer. I will continue to use e-trailer going forward thanks to their excellent knowledge and friendly customer service.

Works good on my utility trailer. Can't tell much difference empty, but loaded (+/-5000#) provides better ride and easier on hauled equipment. Super easy installation

Haven't installed yet on my Keystone Raptor toy hauler but quality out of the box looks amazing. I installed the lighter version of these on my bass boat and it made a huge difference.

I installed the EZ-Flex equalization system on my 2021 Keystone 5th wheel this past weekend, i replaced the RoadArmor system which had all bushings worn out in less than 2 years. The EZ-Flex is built so much more sturdier than the road armor and it has grease zerks built in for easy lubrication for longer lasting system. Very happy with the service i received!

  • Replacement Leaf Springs, Shackle Straps, and Wet Bolts for 2021 Grand Design Imagine XLS 21BHE
    Hi Sam! For wet bolts and heavy duty shackle straps you can use the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR. This comes with 2-1/4" long shackles which match the length you have now. Grand Design does a great job listing parts on their site but the leaf spring length isn't something they cover. You will need to measure the length of your existing leaf springs to find the right replacement. You can use either of the methods outlined in the attached picture to measure...

  • Replacement Equalizer and Shock Kit for a 5th Wheel Trailer
    Hey Jim, welcome back! There's not much difference performance wise between the Lippert Road Armor and one of the Dexter E-Z Flex Equalizers like item # K71-655-00, item # K71-654-00, and item # K71-652-00. Above all you want to make sure your replacement equalizer matches your current ones dimensions as closely as possible. This ensures your suspension geometry doesn't change or your ride height. The Lippert Road Armor and Dexter E-Z Flex Equalizers both use rubber inserts to dampen...

  • Replacement Equalizer and Leaf Springs for a 2020 Grand Design Imagine 21BHE
    Hey Tyler, thanks for reaching out! Grand Design actually does have some help in that department, since they have a whole "replacement parts" section on their website. To upgrade the equalizers on your 2020 Grand Design Imagine 21BHE you need the E-Z Flex Equalizers # K71-655-00, but when it comes to your leaf springs, I'll need you to lift the frame off the ground (so there isn't pressure on the spring) and then measure from center eye to center eye. Once you have that measurement...

  • 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...

  • Best Cushioned Equalizer Recommendation for 2019 Forest River Wolf Pack 325PACK13
    Hey Andy, the best cushioned equalizer we have for a 7k axle tandem setup with a 33 inch wheelbase would be the MORryde ALLTREK 4000 kit part # MR89DR. This is only option that has horizontal and vertical cushioning so you'll really notice a difference. The dimensions of this match what you have close enough to work perfectly fine as well as these are rated for up to 8k axles so they would for sure be heavy duty enough. Whats the ride quality like currently?

  • Is 1/4 Inch Height Difference Okay For Use With E-Z Flex Equalizers
    Hi Sam, Good question, and the mere 1/4 inch difference in the height is not going to have any type of negative effect on your trailer so you can 100 percent use the E-Z Flex Equalizers # K71-655-00. These are a smart choice as they'll make a nice difference in how your trailer rides due to its rubber cores absorbing bounce and shock.

  • Determining If Road Armor Shock Absorbing Equalizers LC696740 Fit 2021 Forest River Sabre 5th Wheel
    I would be happy to help you determine if the Road Armor Shock Absorbing Equalizers # LC696740 you were looking at will fit your 2021 Forest River Sabre 36BHQ, but this is not information that we have on hand so you will need to measure your current equalizers. The # LC696740 measure 6" center to center of the horizontal mounting holes so as long as that matches your current equalizers this would be a great upgrade option for you. These equalizers are designed for 3500-8000lb axles so...

  • Will Dexter E-Z Flex Equalizers Work With 3-1/4" Long Shackle Straps
    Hi Brandon; the Dexter E-Z Flex Equalizers # K71-655-00 will work with your 3-1/4" shackle straps. It is also the perfect size for your trailer since it has the same 7-3/4" measurement. The kit only comes with the equalizers so there are no shackles straps with it that wouldn't match. If you're wanting to upgrade to heavy duty shackles and wet bolts you can use the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR76ZR. This has 3-1/8" long shackle straps which is probably what...

  • Recommended Dexter E-Z Flex Equalizer for 2004 NUWA Hitchhiker II LS to Widen Axle Hanger Spacing
    I recommend using the E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle - 5-5/8" Equalizers # K71-652-00 which is compatible with axle spacing of 33 inches on center. It is okay to move your outside hangers to give you more space but there are standard spaces that work well for tandem axle trailers that you will want to stick to. If you want 35 inch axle spacing, then you will move the hangers and use kit # K71-653-00 which has wider equalizers to make up for the larger spacing....

  • Lift Kit and Upgraded Equalizer for 2025 Forest River Impression 238RL
    Hey Thomas, welcome back! It looks like the leaf springs are already on top of the axle (overslung) so the Correct Track # RR55QX is the best option to lift the trailer. The triple axle kit you were looking at is the one you need for the 2-1/4" lift. For an upgraded equalizer that is compatible with the Correct Track, I recommend the Dexter E-Z Flex Equalizer Kit. You need to choose the kit based on the size of your existing equalizer. If it measures 5-3/4" from the left to right bolt...

  • Best Replacement Equalizers for Dexter 13-122 Equalizers
    Hey Paul, thanks for the information! The Dexter 13-122 are 7-3/4" long so the best replacement for them is going to be the E-Z Flex Equalizers item # K71-655-00. They have a a rubber core that absorbs road shock, reduces chassis stress, and minimizes chucking. When you swap out your equalizers you'll also need to replace the suspension bolts as they are only meant to be torqued down upon initial installation. I recommend the MORryde Suspension Upgrade Kit for Tandem Axle Trailers item...

  • Recommended Equalizer that is 7-3/4" Wide
    Hey Kenneth. All of our equalizer's like the E-Z Flex Equalizers item # K71-655-00 are have 9/16" diameter holes. There are none that have a 7/8" center hole so you'll need to get a smaller bolt. The E-Z Flex Equalizers item # K71-655-00 are 7-3/4" wide and 3" tall. You'll want to replace your current equalizer with one close to the same size. How wide is your current equalizer from the left to the right mounting bolts and how tall is it from the top mounting hole to the center line...

  • Which Dexter E-Z Flex Equalizers Fit 2002 Bass Cat Jaguar Trailer
    Hey Curt! I wouldn't get too caught up in the axle spacing for the E-Z Flex Equalizers # K71-655-00. The best thing you can do is measure your existing equalizer. If your measurement from left to right bolt hole on center is 7-3/4" then this is a good fit. If the measurement is 5-3/4" then the # K71-654-00 is the better option. Matching that equalizer length is the most important part. This keeps your suspension geometry the same so everything continues to work as intended. Both of...

    Hi Rob (great name); the best choice for an upgraded equalizer is the one that matches the size of your current equalizer. There are a number of different designs but you really won't notice a difference in performance from one to another on your trailer. With that 7-3/4" measurement I recommend the Dexter E-Z Flex Suspension Kit # K71-653-00. I have the E-Z Flex on my Jayco and they do a great job.

    Hey Jerry thanks for the picture! I am sorry but you can not just get that replacement rubber spring. You'll need to replace the entire equalizer with the item # K71-655-00. This is identical in size to your current 13-143 equalizer so it will be an exact replacement. I'm guessing your rides gotten awful uncomfortable recently. I recommend replacing your wet bolts and shackles as well since you're going to have to take them off anyways to replace the equalizers. You will need to measure...

    Hey Ken, based on the axle capacities we know your 2017 Grand Design Solitude 384GK has the Dexter EZ Flex part # K71-655-00 that you referenced should be the correct fit but you would want to verify this by measuring what you have now. If the distance between the left and right bolt hole is 7-3/4 inches this is correct fit. This is a very common size so I would be surprised if you needed something different. You can also just measure the distance between your axle centers as well. If it's...

The good news is the Dexter E-Z Flex Equalizer Kit # K71-654-00 is a great upgrade and an excellent match for your setup.

  • Can 5-3/4 Inch or Similar Size Equalizer Replace 7-3/4 Inch Equalizer
    It's not uncommon for a trailer with a 29-1/2 inch axle spacing to use either 7-3/4 inch or 5-3/4 inch (or similar) equalizers but the shorter ones are more commonly used with the 25-1/4 inch leaf springs, like the ones you have, designed for up to 6,000 axles. So, the Lippert # LC279687 could potentially work for you. Keep in mind that the previous trailer owner could have been using shorter shackle straps to make up for the longer equalizers. Otherwise, an equalizer that is too long...
