Average Customer Rating:  4.8 out of 5 stars   (310 Customer Reviews)

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


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.


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!!!


Easy installation and good performance.


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



Excellent . Softer ride.


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.


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.


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


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


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.


Works well with the greaseable shackle kit.


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.


These are obviously better and more heavy duty than the original equipment.They are also easy to install. Very happy with my purchase.


I purchase these for my son's trailer. I fitted a set on my 5th wheel over a year ago and have noticed the difference. I like the fact they are bronze bushing and have grease zerks.


Why didn't I think of this. What a difference every travel trailer needs it. It really takes the abusive shock out of suspension


The wet bolts that were sent are massive, would have to drill out the 3000 and destroy it . Never should have been shipped, sent back . The 3000 is on my travel trailer so I’m happy now.


Probly a good product some how would not fit pretty sure I went over this with sales person but my trailer is 30 in wheel base would not work found out after installed i have them for sale

Its a shame that this will not fit your application. I have sent this over to our customer service department for them to better assist you.


One year and 10k miles later, this was a good investment.

  • How to Tell If MORryde Rubber Equalizers Will Fit Trailer
    I would love to help you upgrade the suspension on your Twilight 2800 travel trailer. The MORryde Rubber Equalizers for Tandem Axle Trailers # MR87ZR that you referenced are a great solution but we do need to double check a few things. First is that this kit is for up to 8K axles with a 33" wheelbase, and then the eyelets measure 6-1/2" apart on center and 3-1/8" down from the hanger (see attached). If this matches what you have then you can use this kit. If this doesn't match what you...

  • How To Tell If MORryde CRE3000 Equalizers Fit A 2021 Keystone Hideout 29DFSWE 1 Can I
    I'd be happy to help, but you're going to need to measure the current equalizers on your 2021 Keystone Hideout 29DFSWE to confirm that the MORryde # MR87ZR are going to fit. The # MR87ZR measure 6-1/2" center to center of the horizontal mounting holes that the shackles get installed into, and 3-1/8" from the center of the upper hole to the center of the lower two holes as shown in the below diagram. As long as these measurements are pretty close to what you have now, this'll work just...

  • How To Tell Which MORryde Equalizers Will Fit A 2012 Jayco 26BH
    Finding the correct MORryde equalizer kit will be pretty specific, so I cannot tell you which will be correct without knowing the wheel spacing and axle capacity, unfortunately. With that being said, if you have the trailer's VIN, you may be able to obtain this info from Jayco. The axle capacity will definitely be something they keep on file, but I cannot say with 100% surety they can tell you the wheel spacing. If they can get you both of these, let me know and I can definitely get you...

  • Can MORryde Rubber Equalizer Kit MR87ZR Fit 2007 Thor 19FQ
    While the MORryde Equalizer kit part # MR87ZR is listed for 33 inch wheel bases the most important dimension of this matches what you need as it has a distance of 6-1/2 inches between the mounting holes which is close enough to your 6 inch dimension.

  • How to Fix Clogged Trailer Equalizer Grease Fittings
    The MORryde # MR87ZR itself doesn't feature grease zerks, so you're likely referring to the bolt holding the equalizer in place, referred to as a wet bolt. If you're certain that the grease gun is working correctly, it's possible that the zerks themselves are clogged. To unclog them, use a hair dryer or a heat gun on its LOWEST setting. Have a helper hold the dryer or gun on the zerk fitting until it's heated, then immediately attach the grease gun and add grease. The new grease will eject...

  • Is There MORryde CRE3000 that Could Fit Wheelbase of 31 inches
    The MORryde CRE3000 # MR87ZR could work for your trailer but you need to take one more measurement. On your current equalizer measure the distance between the lower bolt hole centers. If that distance is 6-1/2 inches or pretty close to that this will work great for you. It's very likely this will work for you and your longer shackle straps are the reason for the difference in wheelbase.

  • How to Pick Out Replacement MORryde Suspension Upgrade for EquaFlexon 2019 Grand Design 381M
    It really comes down to knowing what Equaflex you have now or the dimensions of them and then picking out the matching MORryde kit. The part # MR87ZR is made to fit the most common dimensions as it is for 33 inch wheelbases and has 6-1/2 inches between the front and rear bolt holes with 3-1/8 inches between the holes vertically.

  • How Do I Know If The MORyde Rubber Equalizers Will Fit On My Trailer
    The MORyde Rubber Equalizer # MR87ZR could absolutely be used on an enclosed trailer. The 8K rating would be per axle. It might be more accurate to say that these equalizers can be used on axles 8K and under. So if your trailer is 10K gross weight, a Moryde rubber equalizer is appropriate for that kind of setup. If you want to be sure it will work on your trailer, the best way is to measure the current equalizer. If the length and height match that of the MORyde equalizer then it will...

    You are correct that the 8000lb rating that the MORryde Rubber Equalizers for Tandem Axle Trailers - 33" Wheelbase - 8K # MR87ZR has is the maximum axle rating, and they would work perfectly with your 6000lb axles.

  • Do MORryde Cushioned Equalizers Help Reduce Trailer Sway
    Cushioned equalizers like the MORryde part # MR87ZR can help with sway to a certain extent but they are not known remedies for sway. If you are really trying to prevent sway at the source you would need to move weight forward in the trailer to get more tongue weight and that will do the best job at preventing it.

  • Should MORryde Equalizer Kit MR87ZR Or MR27ZR Be Used With 35" Axle Spacing?
    As your axles measure 35" apart from center to center but the frame hanger spread (FHS) measured 58-3/4", you did go the correct way. The axle spacing is definitely important, but the FHS is more so. Just be aware that you axle spacing may change a little due to the MORryde Rubber Equalizers # MR87ZR being shorter than the # MR27ZR (quick diagram included), but this will be perfectly fine.

    Thanks for the pictures! If you're getting that loud of noise out of your 2019 Jayco Eagle Fifth Wheel's equalizers then it is time to replace them. Greasing them won't fix that loud clunking noise. If your axles are 35" on center then you are going to want a bigger equalizer. I recommend replacing your old equalizers with the MORryde Shock Absorbing Suspension Equalizers for Tandem Axle Trailers w/ 35" Wheelbase - 8K item # MR27ZR.

It's a good idea to go ahead and upgrade your shackle straps and bolts at the same time for that you'd need # MR46ZR as well. I included videos of the products mentioned for you to take a look at.

  • Do MORryde Equalizers Improve Suspension Performance
    Cushioned equalizers do make a significant improvement in ride quality that you will notice when towing your trailer. It gives the cushioning that is somewhat horizontal as well as vertical from the leaf springs so when you hit bumps the shock will be greatly reduced. Then for a wet bolt kit that comes with bronze bushings and heavy duty shackles the MORryde part # MR46ZR would be what you'd need.
