Upgrade your trailer's suspension system with these rubber equalizers for a smoother, more comfortable ride. The rubber insert offers up to 3" of suspension travel for greater shock absorption.


This has been a great improvement to the suspension system on my RV trailer. You can feel the difference going down the road. Would recommend this upgrade if your RV came without this system as mine did. It should be standard on all RV trailers.


Excellent upgrade over the stock equilizer. You can definitely tell a difference in ride quality going over any type of bump and improves porpoising recovery. We did have to readjust our weight distribution due to the extra 3in height the new equalizers add so something to think about. You will notice a difference in ride quality for the better. 5 stars


I replaced my trailers equalizer and shackles with new ones from MorRyde a year ago. Installation was straightforward using my own tools. My stock equalizers were the solid metal ones, the CRE3000’s have rubber bushings to absorb some of the shock. The heavy duty shackles are twice the thickness of the stock ones for extra strength. I also put in greasable wet bolts with brass bushings. I’m totally satisfied with each of these components.


Great addition to any trailer. Very noticeable improvement right away. Installed these on a Winnebago Voyage...straightforward install if you have the space and tools (jacks and impact wrench). Use the wet bolt kit too.


They shouldnt be allowed to sell travel trailers without these on them! This not only calmed down the trailer they help the jarring felt on the truck as well

If you own a brand new trailer or one a few years old out these in right away

By the way my trailer was only 2 years old and old hardware was shot out already


Excellent upgrade to my suspension!




Easy installation and good performance.


Installed on a 2018 Prime Time Avenger ATI. Rear axle failed (lost its arc resulting in a burred spindle and inconsistent tire wear). During inspection of the hanging components, found the OEM shackle links failed or in the process of failing. Took approximately 12 hours (dodging periodic rainstorms) to replace rear axle and the suspension kits and springs for both axles. Installation was straight forward without complexity. I can now rest easy that these parts will last longer.


These Equalizers are a huge step up from stock. It made towing a quiter, smoother, and solid ride going down the road. Very good investment.

After a year of roaming around with our 37 Travel Trailer and the CRE3000s, I have to say there is no update. That is a good thing it still rides, feels, handles, and sounds as great as it did the day we put them on. Great investment without a doubt put em on!


This MORyde tandem equalizer is 3 steps above the cast steel factory equalizer. Fit perfectly and rides much better with the rubber bump stops and all new wet bolts. Near zero chucking and at times I forget it's back there and I highly recommend.


Still haven't put them on yet

We will be here when you do put them on and would love to hear how they are working for you.


They are nice, but the installation was tough. I spent hours working on this only to find out every wet bolt was .015 thousand oversized. No bolt would ever go in, no matter how hard I hammered. I chucked every wet bolt in a lathe and cut down part of the knurls. Something most people do not have access to. Every bolt (knurl) was a larger size.


I had the Morryde equalizer installed & my mpg improved from 10 mpg to 14 mpg.



Excellent . Softer ride.


Upgraded an original equalizer on my 2006 travel trailer. Combined this with the wet bolt and heavy duty shackel kit. Trailer rides much smoother and quieter!!!


The Morryde Equalizers are a great product. Easy to install!


These seem like a solid heavy duty product. I'll run them a full season before passing final judgment.



I like the fit and the ride that the product provides but after a trip to Texas last year the equalizer piece is rusted and looks to be a hundred years old. I thought they would hold up better. Guess I should have coated them with wax or something.

@Jake I recommend using a rust resistant paint like Rustoleum to touch up the Equalizer. Unfortunately rust is known to happen with these systems.


Excellent product. Works very well. Bought with a shackle upgrade.
Feel more confident in my suspension now over the OEM product.


Had these on my previous 5th wheel. They really smoothed out the ride.


Great price and they work great. They are way better the the factory crap originally install at factory.


Delivered today sooner then expected.
today can wait to hit the road and try the equalizers out


I purchased the CRE3000 to replace my CRE3000 that were cracking at the welds. I’m not happy but couldn’t afford to upgrade at this time.


Seem to work good, although I do notice a little more trailer bounce on some road surfaces.


Timely delivery and fits nicely. Had upgraded to wet bolts but to get this with out that upgrade would mean having to take out the bronze bushings.


Simple review.... If you are thinking of these, just buy them. Huge difference in rig control when towing. I will buy these again for my next rig if it needs them. Too bad I waited so long.... Calmed the rig down on the road.
