Features to know about

Built to Handle the Miles: 1/2" Thick Steel Shackles Outlast Factory Parts

Stock suspension hardware can wear out fast when miles start to add up. This MORryde suspension upgrade kit replaces thin factory shackles with 1/2" thick steel straps that are twice as strong as standard parts. The heavy-duty design resists elongation and keeps the suspension tight and stable, extending the life of your trailer’s LRE suspension with Correct Track alignment and lift kit.

Smooth, Quiet, and Easy to Maintain: Wet Bolts Keep the Suspension Lubricated

Creaks and squeaks are often a sign of dry or worn hardware. This kit includes wet bolts with built-in grease fittings that let you easily keep the suspension moving freely. Regular lubrication through these fittings keeps the bronze bushings in top shape, cutting down on metal-on-metal wear and noise for a smoother, quieter ride.

Durable Bronze Bushings for Long-Term Performance

Plastic bushings can fail quickly under load, but these bronze bushings hold up season after season. With an outer diameter of 11/16", an inner diameter of 9/16", and a 1-3/4" length, they’re made to last longer and stay tighter in the spring eyes and equalizers. Paired with wet bolts, they form a solid, low-maintenance setup that resists rapid wear.

All-in-One Upgrade for Triple-Axle LRE Systems

Everything needed to renew your suspension comes in one kit—12 shackle straps, 8 shackle brackets, 4 shear spring brackets, 24 wet bolts, 16 bronze bushings, and 24 locknuts. The 2-1/4" shackle straps and 9/16" bolt holes are sized for a perfect fit on triple-axle trailers using MORryde’s LRE leaf spring suspension with rubber shear springs and Correct Track system. It’s a straightforward way to boost strength, reliability, and ride quality all at once.

Video Transcript for Review of MORryde Trailer Leaf Spring Suspension - Spring Mounting Hardware - MR56ZR

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this MORryde shackle upgrade kit for triple axle trailers with the LRE leaf spring suspension and the OEM correct track hangers. Now, this heavy duty shackle kit is an excellent upgrade for your RV suspension. This kit is designed for triple axle trailers with the LRE leaf spring suspension, and the two and a quarter inch shackles, and the OEM correct track hangers. Now, on this kit, what's nice is it's a half inch thick shackle bracket, which are thicker and stronger.

They're more durable than your standard quarter-inch thick factory brackets. They also use the bronze bushings instead of the plastic bushings for increased durability. And the bolts that are used on these shackles are greasable bolts, also known as wet bolts. They're easily maintained. They help minimize wear and tear versus a dry bowl.

Now basically, in a multiaxial system, the shackle is light, we'll link the springs and the equalizers in your suspension system. And the shackles are the part that'll handle the most movement and weight in a suspension setup, therefore, they're the most likely component to wear, and should be checked frequently. The shackle bolts, these are what'll hold the shackle straps. These are your straps to your leaf springs and to your equalizer. And normally it has dry bolts which over time can wear out and fail.

As we mentioned, these use the wet bolts. So, besides having these thicker straps here, the wet bolts that they use have a nice grease zerc fitting on the end, and that allows you to apply grease to the inside of the bushing. So if you slide your bushing off, you'll see a little hole right here. So when you attach your grease gun to this zerc fitting pump in the grease, it'll go on the inside of the bolt, and come out that hole. And then with your bushing installed, the grease will be on the inside.

So it gives you good lubrication on the bushings. Keeps wear from happening at these connection points. Now, this upgrade kit will replace the shackle straps, the bushings and lock nuts on your RV suspension system. This kit does come with everything I laid out here on the table. It includes 12 of the two and a quarter inch long shackle straps, and they're half inch wide, we mentioned. And when I say two and a quarter inch long, basically they're measured from the center of this hole to the center of that hole. That's the measurement we're saying when it's two and a quarter inches. Comes with over here four of these three bolts straps, 22 of the nine sixteenths by three and three eighths inch long wet bolt. Comes with two of the nine sixteenths by two and seven-eighths inch long wet bolts, 16 of the bronze bushings, 24 of the flange lock nuts. And then right here, comes with eight of the sheer spring brackets with the hardware. Does also come with a nice set of installation instructions that'll describe how this all goes together. And these parts are made in the USA, but that should do it for the review on the MORryde shackle upgrade kit for your triple axle trailers, with the LRE leaf spring suspension and the OEM correct track hangers..

My 2019 Coachman Freedom Express Liberty 320BHDS was chewing the inside treads of tires regardless of rotations. Thanks to Kyle B and Daylon H, your team quickly diagnosed the issue and recommended this suspension upgrade including new 6000lb leaf springs, u-bolts, equalizer and the MORyde wetbolt hardware kit. Installation took the better part of a weekend, but was a complete success. Be mindful of the torque specs and ensuring your RV is properly supported (including axles). Thanks to some recently cut stumps, I was able to support boths sides of the axles to safely torque bolts to 80lbs. RV rides about 1.5 inches higher, but nice and smooth. No noticeable camber with the tires now. Time will tell, but sincere thanks to Kyle and Daylon for taking their time to view my photos and answer questions.

Thanks for the awesome detailed review, Kevin! Really glad Kyle and Daylon were able to help track down the issue and get you pointed toward the right setup. It sounds like you put a lot of care into the install, and it definitely paid off. Making use of those stumps was pretty genius too. Safe travels ahead!

by:
Everything was as listed and packing was done really well. I did have leftover bushings as the MORryde pieces have the bushings already pressed in. Seems like there was a waste of parts as you cannot use these bushings to replace the ones installed in the MORryde kit.

Thanks for the review! Glad everything arrived in good shape and that the packaging held up well.

by:
There's really no comparison as to how much better this shackle kit is. The original plastic bushings were totally disintegrated. Took the 5th wheel for a test drive after installing these and now with the wet bolts installed the suspension is 90% quieter when negotiating my serpentine driveway!

That's awesome to "hear", Tom. I know the clanking of trailer suspension can get loud so if it helped reduce it by that much, I call that a major win!

by:
Bought this kit when I was replacing a broken leaf spring on my tiple axle toy hauler. It's an exact match to the OEM suspension.

Thanks for the great review, Don! Happy to hear the kit was an exact match for your OEM setup and got your toy hauler back in action. We appreciate you sharing your experience, and the photo too!

by:
The installation went well. It took me about one hour and twenty minutes to install the MORryde CRE3000 and the shackle kit on one side because I was cautious, making sure I installed it correctly. The other side went much faster, completing it in about 30 minutes. I am looking forward to seeing how the camper responds to rough roads.
by:
Our RV tows and rides so much better since installing this suspension!
There is no longer any porpoising while towing and I have no worries of ever wearing out the shackles.
by:
Great product even after 1 year. I grease the wet bolts a couple times a year with ease!

I always wanted to replace the stock shackles with this MORyde kit. Fit as expected and am looking for a long life out of the new shackles.

The new shackles with the wet bolts have worked as expected for 6000+ miles. Important upgrade for anyone who plans on towing their camper any distance.

@Brian That's some distance! Was this over time for several trips or did you go on one long trip?
by:
Installation was pretty straight forward. My travel trailer pulls better and feels smoother going down the road.
by:
This is the second travel trailer / 5th wheel that I have upgraded with the MORryde wet bolts and shackles. The installation is pretty straight forward, the second side always takes me quite a bit less time to complete than the first side. I spent over 4 hours on the 1st side and about 1.5 hours on the second. I also installed a new MORryde equalizer at the same time. The original equipment nylon bushings were almost worn completely through on every bolt. I had 2 shackled that bolt hole had become an oval instead of round, and one shackle that was cracked. I have not had a chance to take my 5th wheel out since completing the job,but the creaks and squeaks that were present when raising and lowering the front landing gear are gone. I expect that it will ride and tow much smoother, just as my travel trailer did when I made the same upgrades. Great products, much better quality than factory installed parts.
by:
Removed the old hardware and plastic bushing were found worn and junky. New hardware went in fine and felt great. All torqued up and ready for the road! Peace of mind is worth it!
by:
Excellent upgrade! Items shipped fast, were packaged well, and install was a breeze. All the stock nylon bushings were trashed.
by:
Real stout, should last a long time, great upgrade, should help long travels better, I added a lippert suspension at same time. Takes quite a few different tools. But not a super hard job ,if you have a few of the right tools and mechanical know how to.
by:
This was a great upgrade to the OEM suspension components on y travel trailer. The trailer is only 18-months-old, but as you can see in the video, the original suspension was completely shot after about 20,000 miles.
The kit replaces the OEM nylon bushings with bronze, and more important, contains wet bolts with zerk fittings. The shackles are much more heavy-duty than the originals. The kit was easy to install in an afternoon.

@GwendolynY We're on the road 3 months out of the year, and we're always on the move. Those bushings have about 23,000 miles on them.
by:
These shackle straps will keep you from being broke down on the side of the road. If you tow significant mileage toss the factory straps before you wear through them.
by:
Bought these to replace existing shackle straps on my travel trailer that had warn dangerously low. These shackles were twice as thick as what was on the trailer at delivery. Very easy to install (save some time and make sure the ground is level) and don’t forget to grease!
by:
I replaced my shackles on my tripple axle trailer with heavy-duty ones from e trailer, while I was at it I replaced all the equalizers and added wet bolts and brass bushings. I had never done work on a trailer Suspension before but with the help on e trailer I got it done. I no longer have my shackles flipping over and my boat trailer pulls like a dream. E trailer is great to work with and very helpful. I will definitely use them again when the time comes
by:
They are better than original. They have bronze bushings instead of oem plastic and they are greaseable. The most important part to me is that I was able to call etrailer and tell them about my need for these with the Road Armor and they were able to tell me which set to get. This modification allows me to pull the trailer safely and without issue down the road.

This was my first tandem axle unit. As I was pulling it home, it had such a twitch and shake that I pulled over to check it out. All bolts, etc. looked to be fine. I came across a review of the Road Armor and replaced my existing suspension. I have had zero issues and the trailer pulls smoothly. I highly recommend them.

@John Besides the original twitch and shake, I am glad to hear everything is working smoothly now! Did you end up replacing the original equalizer with a Road Armor? They do make a difference when they are new so I am glad its working out well for you. What trailer did you replace all this on?
by:
This is a great set and exactly what I was looking for, only thing I found out when I opened the package is it for one side of the trailer only. I’d would be nice to see that listed. Do you offer a complete set for the entire trailer?

The kit is intended to replace the bolts, shackles and bushings on both sides of a tandem axle trailer. It should have included the following: 8 Shackle straps 8 Wet bolts (for attaching the springs to your equalizers) 6 Wet bolts (for suspending your equalizers and springs from the hangers) 14 Bronze bushings (for spring eyes and equalizer bolt holes) 14 Locknuts If anything is missing, let me know and I'll get it straightened out for you.

by:
Great kit, included everything I needed. It also includes the fixed spring bolt for the outsides.Seemed well made and arrived fast. Really like how heavy duty the shackles are. I installed the grease zert side to the inside due to having removable fenders and didn't want to catch a zert and shear it off.
I had an issue pressing the brass bushing into the equilizer so may have to see if those are available separately later on. But that was an equalizer issue. If the bushing doesn't go into the new equilizer smooth, ream it with a drill bit first so the bushing doesn't get messed up
by:
I did not realize how bad the original bushins in the suspension were. I should have replaced them long before I did. At least I caught it before thr equalizers and springs needed to be replaced also.
This kit was the exact parts that I needed.
The kit arrived very quickly and was in perfect condition.
Thank you so much for the help I received when ordering the parts.
by:
After pulling the travel trailer over some very rough roads, when entering the trailer I found no doors or drawers opened and nothing out of place. The ride was much smoother and the trailer seemed to track better behind the tow vehicle.

  • Recommended Suspension Enhancement For A 2017 Grand Design Reflection 29RS
    We can definitely help upgrade the suspension on your 2017 Grand Design Reflection 29RS. For a shackle/bolt kit, your best bet will be one of the MORyde suspension upgrade kits. We will want to confirm the length of the current shackle straps (measured center hole to center hole). For a tandem axle trailer we have the # MR46ZR which comes with 2-1/4" long shackles, or the # MR98ZR which comes with 3-1/8" long shackle straps. These MORyde kits are great quality and will be a nice upgrade...
