every thing ordered fit perfectly a little labor intensive but job completed in approximately 6 hrs shear springs will make a big difference as the old ones had worn out and were splitting bad on left side not so much on right but replaced both sides and all bushings and new wet bolts and shackles now the suspension is like new as my Montane is 10 yrs old

You need to make these brackets fo the sumo spring. My wet Bolt kits were great ! Much needey.



They have been working great!! Those brackets give more contact for the Sumo Springs.

@Scott We're glad to hear that you're still happy with your purchase, thank you!



The MORryde leaf spring upgrade with he grease fittings has been great! They are night and day different from the stock ones.

@Scott We're glad the upgrade kit worked well for you!


I like that I can grease the bolts as the old ones were seized up. What I do need is four more bolts like the ones that go with the shackles for the other end of the spring. The existing springs had 1/4” positioning plates. I used existing bolts for now. Do you sell just four of the longer bolts?

We do not have longer wet bolts then the ones that came with the kit which are nine sixteenth bolts that are 3.375 inches long. If you just wanted four more of those bolts we do have them separately as part # MR52HR.


I just installed these today with the help of a talented friend. It took us about 3 hrs total and there were absolutely no surprises whatsoever. We lifted one side of the trailer and completed the work with the other side resting on the tires. I thought the weight of the trailer on the other wheels would mess with us but it had no bearing on what we were doing, it may have even helped us. After finishing the first side in 1 1/2 hrs, we did the second side in a little over an hour. I was surprised. After finishing each individual side we greased the zerks, installed the wheels and tires, and moved to the other side. I'm very impressed. These shackles are twice the thickness of what came with this Jayco RV. So far I'm a happy camper. I can't imagine any issues going forward, but if any crop up I will surely report back.


Just received the Morryde wet bolt kit and installed it his afternoon. The cost was a little more than Amazon but was available a month sooner, helping me get back on the road. The kit was well packaged and easy to use. I recommend viewing a [online] video regarding installation, there are many out there.


This Kitty had everything I needed to came the bushings and shackles! William was extremely helpful in finding the correct parts. I received them very quickly. I attached a photo of the old ones. Definitely needed replacing. This job has some difficulty. You definitely need some jacks to support the axle. But I took my time and used the jacks to help me.


I had worn out my original shackles (nylon bushings, dry bolts, thin shackles) and ungraded to wet bolts, brass bushings, and thick shackles. I ran into a problem when I discovered that the non-shackle bolts supplied were too short for my Correct-Track system. I used the old (dry) bolts to complete the job.


The wet bolts and brackets were delivered in a box that was destroyed with the parts being visible. The grease zercs on the bolts did not work and had to be replaced. MORyde nor retailer would replace them without a ton of photos and emails. I wanted to finish the repairs so Inbought them at our local auto parts stores for under $8.00.



With proper preventive maintenance the bushings and wet bolts are doing great.


This Hardware kit combined with the Dexter EZ-Flex equalizer seem to be a very cost-effective solution. I am always looking for better reliability, and long-term use. After installing this new equalizer suspension system, I am confident that the ride will be much smoother, and not nearly as squeaky as the original manufacture set up on my enclosed trailer (Ragen 24C). The OEM hardware, including a triangular equalizer, had completely worn the plastic bushings and every hole that had a bolt running through it was obround. After worrying something would break on several trips, the satisfaction of installing this upgraded system and knowing it’s right is peace of mind.
-Bronze bushings are better than plastic.
-Zerk fittings are better than none.
-Shackle plates twice as thick
Don’t even try installation without air tools! Use two floor jacks to deal with axle twist but otherwise instructions were good. The first hardware kit sent to me was incorrect, so be sure to measure all your hanger brackets and get the right kit. Etrailer was very helpful to get the parts required to get the job done.


Fantastic Shackle Upgrade. The Shackles themselves are probably two times as thick as the original. The Greaseable Zirk fittings with brass bushings make it easy to keep the shackles properly lubed so they dont grind down like the original hard plastic bushings.

I'm frankly amazed the originals didnt break thro0ough the shackles. But I have zero worries with this new kit. We also paired this with the Moryde CRE-3000 hanger upgrade, which makes the trailer ride much smoother.



So it’s been a year since we made the upgrade on our trailer, and frankly we could not be happier. One of the side benefits of this upgrade has been a smoother tow with less chucking overall. And we know it’s the MoRyde system that’s responsible because that’s all we changed to get this new experience. We are still 5 stars on this purchase.


Terri N was very helpful making sure I was ordering the exact kit needed. It arrived promptly and everything was there for the upgrade. If I'd followed the included instructions, everything could've gone faster on the curb side. After
reading them, the road side was completed in half the time.


So far so good I was able to do the install myself with minimal tools. A lot of elbow grease. Took me about eight hours from start to finish. I already had brass bushings installed but they definitely needed to be replaced. We don’t travel until the end of August 2023


I didn’t realize the junk bushings that the camper manufacturers use and when I pulled the original leaf spring bolts and bushings out, it was obvious they were trashed and had a lot of slip because the cheap plastic bushings had simply worn away. I saw this equalizer unit that added shock absorbing rubber within the assembly and am glad I got it or I would have kept towing with the worn out spring bushings. Before installing this equalizer, I had drawers inside the camper that would pop open during travel and none of that happens with this equalizer so it’s obvious the camper is no longer getting beat on during travel. You can also tell that it goes much better (smoother). Very happy I purchased these. I just wished the rubber in the equalizer would never wear out and eventually need replacement again because I tend to keep my campers for a long time. So I will need to keep an eye on the rubber to know when to replace them again.


Definitely a smoother ride for the trailer, less bucking and noise. After two bent spindles, the MORyde system made our lives on the road for 10’s of thousands of miles much safer and extended tire the mileage.



After replacing worn tires, bending two axles, and porpoising over the rough highways, we purchased the equalizer it, then traveled coast to coast, around Lake Superior and Lake Huron with no issues. From the start, the ride was noticeably smoother, and the jerking was gone!


Excellently made!!! When towing our 5th Wheel a 2018 GD Solitude, the difference is night and day so smooth. Since we upgraded to have both the HD Schackles and ALLTrek 4000. I only wish we had done that from before taking the trailer off the dealership lot.

Thank you.


Fit perfect and is a major upgrade to the standard shackles. Highly recommend


Should have installed these from day 1. What a difference these made with the MORryde CRE3000. My next rig will have the upgrade if needed. If you are on the fence, get off it and just buy these. HUGE IMPROVEMENT!!


After over a year of use I have to recommend the MORide suspension upgrade highly. My trailer rides much smoother and is considerably quieter after the install of this product. Installation is straight forward and not difficult at all.


The kit is nice however the bolts are junk. I had to replace them with grade 8 hardened bolts with nylon locking nuts.
The reason for this is the threads on the bolts kept stripping.
Infact they stripped in such a way that I could not remove the nuts without cutting them off.
Some of the ones I did not replace right away on a trip from Rhode Island to Florida and back. Had worked themselves free.
I would buy the equalizer but definitely not the bolts


During one of our longer trips one of the spring shackles wore through and disengaged. At this time the spring end became pinned against the frame held in place by a aluminum angle iron I installed to hold the underbelly secure. The only thing that kept the suspension from collapsing completely was plates i had welded to close the ends of the spring hangers to prevent the ears from breaking apart. I pulled the trailer several hundred miles until excessive tire wear made me aware of the damage. Ruined a new set of Goodyear Endurance St’s. The MORryde shackles are so much thicker and the wet bolts ease the wear as the replaced spring bolts were showing lots of wear. All this provides peace of mind going down the road.


The install was very easy. The equalizer are very well-made. You could feel the difference in the ride of the trailer. I would highly recommend it. It’s an excellent product by Morryde. Thank you trailer for all your help it’s greatly appreciated!


Replaces worn out and broke shacked and equalizers. Updated bolts to wet, should make quite a difference. This is how we got it home.

Had to get help getting the old bolts loose.

Found equalizers with e-trailer help.


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.


Crazy Awesome kit. Much stronger than stock. Replaced bad bushings and provided greaseable bushings and pivot points. This will always be my first RV upgrade if I get another trailer. Original shackles fell apart after 5,000 miles and caused uneven tire wear. New shackle kit fix that issue also.


I had a leaf spring break on my travel trailer and had some difficulty finding a local dealer for the parts. After doing some google searching, I came across etrailer. I matched the spring size and weight capability with one on etrailer and they shipped it super fast. I also ordered the suspension upgrade kit to go along with the new leaf springs. Ordered on Saturday and got it on Wednesday. I will be coming back to etrailer. Thanks for helping me get my camper back on the road.
