Features to know about

Long-Lasting Strength for Heavy Use: 1/2" Thick Steel Shackles Handle the Load

Factory shackles wear out fast under miles of towing. These heavy-duty 1/2" thick steel shackle straps are twice as strong as most stock parts, giving your suspension a solid upgrade. They replace your existing shackles to tighten up the system and bring back that steady, confident feel on the road.

Keep It Lubricated and Quiet: Greaseable Wet Bolts Simplify Maintenance

A noisy, dry suspension is no fun. The kit’s wet bolts come with built-in grease fittings so you can keep everything lubricated without tearing it apart. Regular greasing keeps the movement smooth and quiet, cutting down on wear and keeping your setup in top shape longer.

Durable Bronze Bushings for Smooth Motion

Plastic bushings just don’t last when the miles add up. This kit swaps them for precision-fit bronze bushings that hold up far better under load. Working together with the wet bolts, they stay lubricated and resist elongation, helping the suspension move smoothly and stay aligned.

Complete Hardware Kit for a Solid Refresh

When it’s time to overhaul worn suspension parts, having everything in one box makes it easier. The kit includes 8 shackle straps, 4 shackle brackets, 12 wet bolts in 9/16" diameters, 8 bronze bushings, and (12) 7/16" locknuts. Each piece is built to the right spec for tandem-axle trailers with MORryde’s LRE leaf spring suspension and Correct Track system, so you can bolt it all together with confidence.

Built to Go the Distance: Designed for Rough Roads and Heavy Miles

This upgrade kit extends the life of your suspension hardware and keeps your setup tight, even after long miles or rough terrain. The thicker shackles, bronze bushings, and greaseable bolts all work together to deliver a stronger, smoother, and lower-maintenance suspension for every trip.

Video Transcript for Review of MORryde Trailer Leaf Spring Suspension - Spring Mounting Hardware - MR29ZR

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this MORryde shackle upgrade kit for the tandem axle trailers that have the LRE leaf spring suspension and the OEM correct track hanger. Now, this heavy duty shackle kit is an excellent upgrade for RV suspension. This kit uses the 1/2 inch thick shackle brackets which are a lot thicker, and stronger and more durable than the standard 1/4 inch thick factory brackets. They also use the bronze bushings instead of plastic bushings. These bronze bushings will increase durability and they hold up a lot better than the factory plastic bushings.

And the shackle bolts on this upgrade kit, they use greasable bolts, which are also known as wet bolts and those are easily maintained, help minimize wear and tear versus a tri-bolt. Now, in a multi-axle system the shackles right here, this is what'll link the springs and the equalizers in your suspension system and the shackles are what'll handle the most movement and weight in a suspension setup therefore, they are the most likely component to wear and they should be checked frequently. Now, the shackle bolts which holds the shackle straps to your leaf springs and to your equalizer, they normally use dry bolts from the factory which, over time, can wear out and fail. This nice upgrade kit, besides using the thicker straps also uses the wet bolts, we mentioned. These are shackle bolts that'll have a grease Zerk fitting on the end, allows you to connect a grease gun to this and apply grease to the inside of the bushing.

So, when your bushing is on here the grease will come out that hole and it greases the inside of the bushing, keeps that wear from happening at the connection points. Now, this upgrade kit will replace the shackle straps, the bushings, bolts, lock nuts on your RV suspension system. Everything laid out here on the table's included. I'm gonna go through em all. Comes with eight of these 2-1/4 inch long, 1/2 inch wide shackle straps.

Now, when I say 2-1/4 inch long what I'm measuring is these from the center hole here to the center hole here. So that's a 2-1/4 inch long shackle strap. Comes with 12 of the 9/16 diameter by 3-3/8 inch long wet bolts, eight of the bronze bushings, 12 of these 7/16 size flange lock nuts, the four shear spring brackets and then in this bag there's 16 of the 3/8 inch diameter yellow zinc bolts and the 16 3/8 inch size zinc lock nuts. Does come with a nice set of installation instructions that will describe how everything gets installed and these parts are made in the USA. But that should do it for the review on the MORryde shackle upgrade kit for the tandem axle trailers with the LRE leaf spring suspension and the OEM correct track hanger..

Extend the life of your trailer's suspension with this heavy-duty hardware kit. 1/2" Thick steel shackle straps will outlast the standard straps on your double-eye leaf springs. Wet bolts and bronze bushings help keep your setup lubricated.

by:

Great upgrade to wet pins and bronze bushings and heavier shackles instead of the dry plastic bushings with much thinner plate shackles. Did the upgrade just in time as several shackle plates were starting to egg out and the plastic bushings were worn through.Camper Model Grand Design XLS 23LDE



by:

Make sure your suspension is in top working order and keep them lub’ed. Perfect replacement parts, thanks E Trailer!



by:

Installation was pretty straight forward. My travel trailer pulls better and feels smoother going down the road.



by:

Heavy duty shackles, installed in a few hours.
Make sure you measure all of the bolts, the bolts supplied for the end of the spring (not the shackle bolts) were to short for my camper.



by:

Great upgrade to stock shackles and bolts. The grease from the wet bolts also quiets down all the noise from the stock plastic bushings.



by:

My PJ trailer with 3500lb axles had 3.5" center eye to center eye shackle straps and phone support said 3 1/8" would work. Assembled fine and have had no issues.



by:

I installed these along with cushioned equalizer and shocks on my 37' 5th wheel. I have less fear of the cabinets falling off the wall on the great interstate road system!
I should have done this a long time ago.



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.



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:

Rear spring hangers broke off of my triple axle toy hauler. Repared/upgraded hangers with thicker hangers and Vee braces. One of the equalizers was also broken. Researched options, found the Moryde system best fit my needs. Also installed upgraded wet bolts and shackles. Really straight forward install. Would strongly recommend the use of heavy-duty ratchet straps to aid in moving axles back into position. Did it as a one person job.



by:

Great product even after 1 year. I grease the wet bolts a couple times a year with ease!



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.



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.



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:

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:

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.



by:

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.



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.



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!



by:

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.

  • Which MORryde Suspension Upgrade Kit for Trailers w/ LRE Suspensions Fits 2019 Jayco Pinnacle 38FLWS
    Hi Willie; the only difference between the two kits is that one is made for trailers with Correct Track installed. It sounds like you do not have this on your 2019 Jayco Pinnacle 38FLWS so you need the # MR79ZR. If you have Correct Track you need the # MR29ZR instead.

  • Recommended Lift Kit for a North Trail 24RL 5th Wheel Trailer
    Hey Marv! I have a couple of options to lift your North Trail 24rl 5th wheel trailer. Which one you go with is going to depend on the orientation of your axles with your leaf springs. If your axles are already below your leaf springs your only option is to use the Correct Track Trailer Alignment and Lift Kit item # RR23QX. This kit mounts to your spring hangers and moves the attachment point down 1-1/4" or 2-1/4" giving you an equivalent lift. If your springs are below your axles you...

  • Suspension/Level Issues Flagstaff Vlite 30WTBSK
    Examine how different, if any, your trailer suspension sets when the trailer is disconnected from tow vehicle, level and unloaded with empty water/waste tanks. If you still have this measurements of uneven from side to side you will need to address possible worn/damaged suspension issues. If you have a proper setting travel trailer you need to adjust the load of your trailer.
