Features to know about

Smoother Towing on Rough Roads: Rubber Core Cushions Every Bump

Long miles and uneven roads can make a trailer bounce and chuck back and forth. The E-Z Flex equalizer fixes that with a built-in rubber core that absorbs road shock and smooths out the ride. It cuts down on harsh jolts and vibration so your trailer tracks steady and your gear stays put inside.

Keeps Your Setup Level: Fits Without Changing Ride Height

You don’t have to worry about losing your trailer’s stance when upgrading. This equalizer works with existing hangers and doesn’t alter ride height. It’s a direct replacement for standard cast equalizers, making it an easy way to get better ride quality without changing geometry or clearances.

Built Strong for Long Miles: Sturdy Steel with Bronze Finish

Durability matters when you’re hauling heavy loads and hitting rough pavement. This equalizer is built from strong steel that holds up under stress, with a bronze finish that resists corrosion from weather and road grime. It’s made to last through years of towing without losing strength or finish.

Precise Fit You Can Count On: 9/16" Bolt Holes and 8-3/8" Spread

Getting the right fit keeps the suspension aligned and working properly. With 9/16" bolt holes and 8-3/8" between the outer bolts, this E-Z Flex equalizer matches standard setups on tandem- or triple-axle trailers using 1-3/4" wide double-eye springs. The measurements are dialed in so everything lines up cleanly for reliable performance.

Video Transcript for Feature Review E-Z Flex Equalizer for 1-3/4" Double Eye Springs

Hi there I'm Michael with etrailer.com, today we're gonna take a quick look at this replacement E-Z Flex third axle equalizer. This is going to replace the third axle equalizer for your E-Z Flex Suspension system and the kit that you see on the screen there. So if you have that system already installed on your trailer and that third axle equalizer is no longer working for you, as well as it used to, or it has become damaged, this is going to be an exact replacement from Dexter Axle so that you can get that working again. Just like the original it is going to have that rubber core to isolate and absorb road vibration and impacts help to minimize chucking or that back and forth movement. It's got the same sturdy steel construction to help increase durability and that bronze finish to help resist corrosion. So because this is from the same manufacturer, you can trust, it's gonna work with your system you're not gonna have to worry about compatibility issues or anything like that.

But just to give you a little bit more reassurance, took a few measurements here. So our overall height I measured right here at our rubber core that seems the tallest part to me or the widest part. So the thickness there is right about two and a half inches. Our length, which I measured from the center of one hole here to the center of our mountain hole, and I got right at nine inches, center to center. Then our overall height, looking at right about six and a half inches.

Our bolt hole diameters there are your 9/16 inch. So, like I said, if you are needing to replace that third axle equalizer on either side of this is gonna be the option that you need direct from Dexter Axle so that you can trust that it's gonna work well for your system to get you up and running again so that your trailer is gonna be a lot smoother for you. That's going to complete our look for today, again, I'm Michael with etrailer.com. Thanks for watching..

I would say a must have for triple axle setups if you have a center axle with shackles on both sides that's just not right.
by:
One heavy chunk of metal. Might have packaged it a little better but came in good shape. The Zirk fittings could have been damaged but were not.
by:
We broke this part when turning and hitting a washout that we didn't see in the dark on a right hand turn. Everything else checked out, so we ordered, has been fine ever since.

You made the road smoother and easier on rough roads

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!

The product seems to be high quality.

Exact replacement parts for Heartland Bighorn trailer and at the lowest price around. Thanks once again, Repeat customer.
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.
by:
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 !
by:
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
by:
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.
by:
Watch the youtube video first easy to install customer service is top notch.

Super fast shipping and great prices and quality parts

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!

  • How to Find the Correct Replacement E-Z Flex Equalizer
