Very high quality kit. Direct replacement for plastic bushings and weak-looking shackles. Best installed with the zerk on the inside, as pictured.




by:

ETrailer was fantastic to work with. I ordered the Morryde SRE4000 upgrade and the upgraded heavy duty shackle kit. Both arrived in a timely manner. The shackle kit did get lost by UPS. I emailed etrailer and Stephanie was absolutely fantastic. She was prompt in her email replies. We had a few emails back and forth. Then I even called one time and she answered the phone promptly and answered my question no problem. And she got the replacement order out right away. Yes, I highly recommend using etrailer. Very professional and knowledgeable.




by:

I have not installed them yet. But I did receive them today and man they look amazing. I was unaware of the existence of these, even when I was looking for replacement parts. Luckily I couldn't find exactly what I was looking for. I called in late one evening and received the help I truly deserved!
I was promptly helped to find the items I truly needed. No more worried for me. I had several issues with my order (all my fault) and each one was addressed perfectly.




by:

Much stronger and should make maintenance a bit easier !




by:

Installation was a little more involved than I anticipated. The bushings fit extremely tight in the Equa-flex equalizer. I then had to ream out the bushing to get the wet bolt to fit through it which was mentioned as a possibility in the instructions but was still an unexpected hassle. Seems cheap that Morryde doesn't make the bushings the proper size for the application in the first place rather than one size fits all with customization. Only had to ream the bushings in the equalizer. The bushings fit well in the springs. Bought this heavy duty shackle kit to help beef up my trailer suspension as I've broken a leaf spring and two spring hangers in less than a year. Should never have a problem with these shackles but am concerned that the bushings will wear out due to the reaming that needed to be done.




by:

Recommend this upgrade to anyone, frozen shackle bolts are a thing of the past! Uncomplicated install ( after grinding off the old, frozen bolts, and driving out the shafts with a sledge!) They work as designed.




by:

They are made heavy enough, BUT the holes in the link plates do not line up with the holes in the other side. I had to make them bigger because I had my trailer torn apart before I noticed and couldn't wait for more parts. My advice is make sure all parts fit together BEFORE you take anything apart.




by:

After breaking two shackles last year on this country's well maintained interstates, I purchased this set. The shackles are clearly much thicker and stronger than stock and the wet bolts will ensure proper lubrication of the bolts/bushings. This was an easy install however I would not recommend it for a novice mechanic.




by:

My old bushings were worn completely out. My equalizers were worn completely out. My trailer tires were rubbing the inside of my fiberglass finders. Trailer appears to be lifted 3/4 of an inch. Tires no longer rubbing finders and all of my trailer bushings can now be greased for longer life.

Great product and easy to install.




by:

Excellent shackles! Very well made and strong. The only complaint was the bolts would not align with the shackle holes. The bolts were angled away from each other and due to the thickness of the shackles, I could not bend the bolts together to align them to the holes. I called the techs at etrailer and was informed that several customers had the same issue. I was told to gently and carefully hammer the bolts together and it worked! Go for minute changes as I learned the hard way and bent the first one too much! It is easier to bang them together rather than spreading the bolts apart!!! I love this kit and feel it is a very necessary upgrade from the factory installed kit. I am full time RVer and want the peace of mind that I feel safer.




by:

Very good quality product with additional grease fittings to lubricate all moving parts.




by:

This is a great kit. Will be replacing the straight grease fittings with 90's for easier access but other than that I'm happy with the purchase.




by:

Money well spent. I made the upgrade because the nylon sleeves in the 2 year old Dexter suspension were already shot. The ride is now significantly improved. The added bonus is the problem with bucking and bouncing on concrete highways with expansion joints is no longer a problem. One comment on installation. If you don't have access to the proper jacks and air impact wrench, have a professional do the installation.




by:

I upgraded my 2002 5th wheel after one of my shackles broke. All of my other shackles were oblong, worn out and needing replaced anyway. These are almost twice as thick as the original ones. This ket has brass bushing instead of the cheap factory plastic ones that were all worn through. This should be standard equipment on all campers!




by:

I have not installed yet but these look great. The packaging was not great and allowed some maring on the back of the mount. Doesn’t effect the performance just would expect better packing.




by:

Amazing product! What a difference from the manufacturer to the morryde shackles. What I did find while I was replacing the old bushings to the new ones, was 4 of the manufacturers bushings were completely broken. It was a matter of time before they completely failed while in transit!
I would recommend anyone with an rv to upgrade these components sooner rather than later!




by:

I opened the package and the parts inside looked good the greasable shackle kit haven’t actually installed yet as I’m waiting on my new axles to arrive next week
Prices and quality are great I’d buy from them again




by:

Seems like superior quality products been running with it for a little while so far and no issues




by:

Exactly what I needed and received on time through my expedited shipping request. A very satisfied customer. Thank you very much e-trailer staff !!!




by:

This is a good kit. Having the grease fittings for the shackle bushings will make for a quieter ride and make these things last a long time.




by:

sent low blank email - over 10 reviews




by:

every thing fit just like it it was meant to would do it again on my other trailers




by:

I wouldn't know because they were not shipped on time even though i paid for 3 day shipping and i missed my installation appointment.

I will have our customer service team reach out to you.

by:

I have just received these and I am very impressed with their quality. They are all packaged securely as not to e damaged and are of great quality. They are going to big a BIG improvement over the standard lippert shackle side plates and are substantially and impressively thicker. Great purchase.

  • Length of Smooth Portion of Wet Bolts of MORryde Suspension Upgrade Kit MR76ZR
    The usable portion of the longer wet bolts that comes with the MORryde kit part # MR76ZR are designed to be used with a 1-3/4 inch wide leaf spring but the section of the bolt you are asking about is 2-1/4 inches wide. This is the smooth part of the bolt under the head to the threaded section.

This will be a much more heavy duty option that would have come with your 2018 Grand Design 28BH. With that being said, if your shackles are longer and...

  • How To Determine Correct Wet Bolt/Shackle Upgrade Kit For Tandem Axle Trailer
    I can help you figure out how to determine the best option for a wet bolt/shackle upgrade kit, though in order to determine the correct one you will need to take a quick measurement of the shackle straps on your Jayco Jay Flight. The reason for that is these kits aren't specifically designed for any trailer, so to ensure the best fit you want to get the kit with the same length of shackle straps. There are a pair of options for you, depending on the length of your shackle straps: - 2-1/4"...

That 1/8 inch difference in length will not be a factor for your ride or the fit; the correct kit is going to depend on if your trailer came with factory Correct Track hangers or not: - WITHOUT Factory Correct Track Hangers: MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR76ZR - WITH Factory Correct Track Hangers: MORryde Suspension...

  • MORryde Heavy Duty Upgraded Shakcle and Bushing Kit for Landscape Trailer
    The MORryde Suspension Upgrade kit part # MR76ZR would work great on your tandem axle landscape trailer. It has 3-1/8 long shackles which you might measure what you have now to compare and see if that's what you'd need. The other really common size is 2-1/4 inch which we have with the part # MR46ZR. Either of these will work but you'll want to match the kit to the shackle length you have now.
