Rubber Equalizers Absorb Road Shock and Reduce Chucking

Hauling a 5th wheel or travel trailer that's still equipped with standard steel equalizers is bound to produce a less-than-ideal towing experience. This is because those standard equalizers allow the road shock from your trailer to transfer directly to your tow vehicle, resulting in a rough, bumpy ride.

In addition, road shock can put added stress on your trailer's frame, suspension, running gear, and more, all of which can lead to increased maintenance time and cost. It can also cause damage to the contents of your trailer due to constant chucking and jerking. And the last thing you want is for your electronics to be tossed around inside your RV before you set up camp.

MORryde SRE4000 Installed

These rubber equalizers significantly upgrade your 5th wheel or travel trailer to help solve those problems. Each equalizer contains an extra-thick, heavy-duty rubber shear spring that helps to absorb and dampen vibration and bounce, resulting in a less bumpy ride. The springs also absorb the back-and-forth movement to reduce chucking and jerking so that you don't get thrown around inside your cab. The rubber used in these inserts is thicker than what's found in most other equalizer upgrades, making this kit a premium suspension option for your trailer.

Each of these equalizers also offers up to 4" of up-and-down travel. The more travel your trailer's suspension has, the better it is able to compensate for road shock. When you hit a pothole, for example, these equalizers allow your suspension to account for that dip on one side so that the opposite wheels aren't forced to compensate. As a result, you'll get an ultra-smooth ride, even when youre driving over uneven campground roads or speed bumps.

X-Factor Crossmember Reinforces Trailer Frame

MORryde X-Factor Crossmember

The included X-Factor crossmember reinforces your trailer's frame, giving it added support and stability. The crossmember reduces the lateral strain on your trailer by up to 90 percent, extending the life of your trailer.

Easy Installation

These equalizers directly replace your trailer's factory equalizers, so installation is straightforward. Simply remove your factory equalizers and replace them with the MORryde rubber equalizers using the included shoulder bolts.

MORryde Shackle Upgrade Kit

While you're replacing the equalizers, we recommend using MORryde's suspension upgrade kit (sold separately) to upgrade your shackle links as well. Factory shackle links wear out pretty quickly and easily, so replacing them with MORryde's thick, heavy-duty shackle links will save you the time and effort of having to frequently replace them. Not to mention you'll get easy-to-grease bolts and long-lasting bronze bushings with the kit for a totally upgraded setup.

MORryde SR4000 Install with Crossmember

Once the new equalizers are installed, slide the ends of the crossmember down over the wet bolts to bolt it in place. Adjust the beam to the correct length, tighten down the bolts, and you'll be ready to go.

Video Transcript for Review of MORryde Trailer Leaf Spring Suspension - Equalizers - MR72TR

Hello, everybody. This is Jeff at Today, we're gonna take a look at the MORryde rubber suspension upgrade for triple axle trailers with 35 inch wheelbase, and that have the correct track alignment and lift kit. Now, this will upgrade your towing experience, using this bolt-on suspension system for your fifth wheel or travel trailer. And as we've mentioned, it is designed to fit triple axle trailers with a 35 inch wheelbase. The equalizers right here, these are rubber equalizers, which will replace your stock equalizers for a lot smoother ride.

Wanna zoom in and show you right here. You can see right all this is rubber. It's a rubber shear spring which will dampen any road shock. And it does provide up to four inches of suspension travel. It does reduce any back and forth chucking.

And these do require less maintenance than the equalizers that have the air bags. Now, these included X-Factor crossmembers right here. They will provide an added lateral support, and help reduce any stress on the frame. The X-Factor crossmembers are installed at the equalizer hangers. And what's nice about these is they're a two piece, so they do slide in and out.

And you slide them to the correct width for your trailer, and then you bolt them into place. The bolt-on design makes the installation very quick and easy. Now you can see, I laid out all the hardwares included for mounting your crossmembers and the equalizers. And now the bolts and the shackle straps for mounting your leaf springs, those items are sold separately on our website. These parts are made in the USA.

Again, the specs. The axle capacity these will work on is 5,200 pound up to 7,000 pound axles. But that should do it for the review on the MORryde rubber suspension upgrade for triple axle trailers with the 35 inch wheelbase, and the correct track alignment and lift kit..

Designed for your 5th wheel or travel trailer with a Correct Track alignment kit, these heavy-duty rubber equalizers absorb road shock and reduce back-and-forth chucking. Great for all types of terrain. Steel crossbeam helps reinforce trailer frame.


One of the equalizers (SRE4000) failed after less than 500 miles. Had to go through MorRyde and they sent me replacements and stated that the SRE4000 has been replaced by AllTrek4000 (which is the replacements they sent. They are also cheaper than what I bought but they would not refund the difference or the labor I had to pay to the the SRE4000’s installed. I ended up installing the AllTrek 4000’s in the campground while I was on vacation due to the failure.


I feel so much more confident the suspension will hold up to many miles of travel. I love that I can grease the bronze bushings and know that there is maximum protection in those joints. Of course I also love the smooth ride and less disruption inside the camper.


Kit looks awesome and can already tell the difference on the suspension while driving or the train tracks on my way home.


Morryde 4000 equalizers and X factor crossmember went on in a couple of hours in my driveway. Liked the function of the crossmember so much I ordered one for the front and rear hangers as well. Notable difference in how contents rode on test drive, no open drawers like usual....


Part of MORryde premium suspension kit. All together they work great. If you are careful ….with plenty of jacks ….job can be done by yourself.


Replacing 10 year old system with Moryde system greatly improved my 2011 Raptor.


The bolt kit arrived promptly, as is almost always the case with etrailer products, which I appreciated. The packaging however was of poor quality. The packaging inside the box had broken open and the bolts and nuts were loose everywhere inside the box. The box had also been damaged and I thought for sure there must be some parts missing. Thankfully, after getting everything sorted out, I could see I had the same number of bolts and nuts, so I thought I must have all the parts. I didn't contact etrailer about the substandard packing because I thought all the parts were there, and after all I don't think the seller has a great deal of responsibility in how the the actual shipper smashes up the shipping boxes. The only thing I was shocked about was that there were no instructions. ZERO. I realize it's a pretty straight forward process, But, a few basic instructions would have been helpful. And, after watching a few [online videos], there are plenty of 'helpful hints' that could have been included in the package. After laying out all the loose pieces and figuring out where everything goes, it's fairly straight forward (watch a few [online videos] first, and I don't recommend the one from Morryde, they edit out a couple critical parts the are a pain in the butt to do). I ordered the bolt upgrade as well as the Morryde SRE-4000 suspension with the cross support bar. The box that came a couple days later with the SRE-4000 and cross bar was in perfect shape, had all the contents, but again ZERO instructions. Watched a couple more [online videos] and figured it out. And just FYI, all the parts did NOT fit my Forest River 2916-G Toyhauler. The small 3" bracket plate that goes behind the trailer bracket that holds the new cross piece support bar is too short for that trailer frame. It's not a huge deal to temporarily put the support bar in place and mark the bracket so you can drill a hole through the bracket and then you can use the supplied parts (basically making the parts fit). So, for me this was a 2 day job (4 hours each day) for a 69 year old man with a bad back, working by himself with 2 floor jacks,4 jacket stands, outdoors on a concrete driveway.

Product is great. Packaging is poor. Loose bolt kit in damaged box caused missing items that are needed for install.


Everything looks great. Will not be installing for about a month, as the camper is in winter storage. Quinn was very helpful and professional.


This unit has made the 36 ft. toy hauler fifth wheel tow much smoother. I am very satisfied by the improvement it has made in towing this heavy trailer.


excellent experience fast shipping and great price


This suspension upgrade really softened the ride things inside the camper are far less jostled


They are working pretty good now. The first set failed. Maureen had to send me a second set, and I have not gone that far on the new set.




Improved the ride of my trailer tremendously!! Stuff is where I put it when I arrive. Was hoping for a lift out of it but got less than 1/2”. The ride quality is enough for 5 stars. Very little chucking now.


The SRE 4000 equalizers made my Jayco Northpoint camper tow better, more stable with much less bouncing than the old CRE 3000. very happy with the product.
Vicky N at was most helpful with info about product & company policies relating to warranty & return issues & application of product.


This looks to be a great product and I’m excited to get it installed and take the camper for a test the ride. Unfortunately it will still be winter for awhile here. The equalizer looks like it will really soak up some road bumps with the rubber suspension. And the cross bar will help out with the sway.


Shipping was quick. Had a problem with some hardware missing and the issue was resolved quickly and all good.


Notable difference also unheeded to the wet bolt kit, difinatley recommend


Our middle leaf hanger was starting to bend. We bent it. Ack the best we could, welded a couple supports on the frame and installed this to help keep the hanger from bending in again. Was a nice kit that allowed us to upgrade the equalizers while we were at it. Pretty simple install but we did have a little trouble getting the two crossmember pieces to line up just because the one hanger was still a little bent. We were able to get it straightened out and got it all bolted together. Like the piece of mind that this will bring


After placed an order it was amazing how fast it showed up to the door, Packaged well, What an upgrade over stuck.


Just came. Have not installed.
