Features to know about

Tougher Hardware for a Longer-Lasting Suspension: 1/2" Thick Steel Shackle Straps

Factory shackles wear out fast under real miles. These 1/2" thick steel shackle straps are twice as thick as most stock parts, giving your suspension the strength it needs to stay tight and smooth over time. The heavy-duty brackets are built to replace your existing hardware and prevent elongation, so the connection between your springs and equalizer stays solid mile after mile.

Smooth, Quiet Operation That Lasts: Bronze Bushings and Wet Bolts

Nothing ruins a drive like squeaks and clunks from worn bushings. This kit swaps out plastic bushings for durable bronze and adds wet bolts with built-in grease fittings. Together they keep the suspension well-lubricated, reduce wear, and make maintenance simple. Regular greasing keeps things quiet and helps extend the life of every moving part.

Built for Rough Roads and Heavy Loads: Reliable Mounting for LRE Leaf Spring Suspensions

Rough roads and long hauls demand more from your suspension. Designed for tandem-axle setups with MORryde LRE leaf spring suspensions, this kit brings the durability and support needed to handle rubber shear springs under load. With shackle straps measuring 2-1/4" center-to-center and 9/16" bolt holes, every component is sized for a secure, precise fit.

All the Essentials in One Kit: Complete Hardware for a Solid Upgrade

Everything needed to upgrade your suspension is here—8 shackle straps, 4 shackle brackets, 12 wet bolts, 8 bronze bushings, and (12) 7/16" locknuts. The hardware installs in place of your old components for a straightforward refresh that strengthens your entire setup and cuts down on long-term maintenance.

Peace of Mind on Every Trip: Heavy-Duty Design That Holds Up

When your suspension hardware is solid, you feel it in the tow. The thick steel, greasable bolts, and long-lasting bushings in this kit keep your trailer steady and responsive. It’s a simple way to protect your investment and make sure your suspension is ready for the next stretch of rough road.

Changed the grease zerks to 90 degrees instead of the straight zerks too close to the tires to hook up grease gun.

Kit was well packaged and arrived quickly. Quality materials and looks to be very well put together. Installation should be a breeze. Looking forward to the benefits of this modification.



by:

Excellent upgrade, heavy duty, easy to install.



by:

Excellent kit!!! Like everything ETrailer sells, this is top shelf!!!



by:

First trip out with the new shackle system felt lime it did when it was brand new, and after a year of trips it still feels like it’s new. And with the grease-able shackles is rides super quiet



by:

Bought this complete kit to replace one I installed back in 2015 and about 30000 miles ago! Cheaper than just bolts and bushings and all the small bolts are now fresh also. Prompt delivery. Hardware is plastic sealed to a card, no worries about something being lost during shipping due to a damaged box.



by:

Great service and fast shipping



by:

Was a direct replacement for my worn out parts. Fast shipping . E trailer is the best supplier I have used in years.

Working very well certainly giving a smoother ride as it should. The other one was completely worn out. Very pleased with it



by:

Replaced our old bolts with these new ones. Have over 6500 miles on them and the trailer pulls alot smoother,less noise from the suspension. This was the right choice to install on our Montana 5th wheel trailer.



by:

These things are substantial ! Very nicely made and packaged. Weren’t hard to install, either. I am very happy.



by:

I’m a happy camper now!!!



by:

Delivered in very good time all parts t here



by:

Product looked very good once they were unboxed only issue was a few of the bolts stripped out while trying to tighten them,had to use old ones to finish the job,hopefully the ones that were used do not strip out while driving,other than that looked like quality metal on the shackles and bushings, will let you know how everything goes,we got a 2100 mile trip out to Arizona to do.

After a shackle broke on the suspension I replaced the entire suspension system and have several thousand miles on the trailer with everything working well. Some of the roads on the Oregon coast are a real test. 2009 Montana. Grant



by:

Have not opened the box yet but the service and ease of doing business was great. My trailer will be happy to.

  • What Is the Best Suspension Refresh and Gooseneck Pin Box Upgrade for My 2013 Montana 3900FB?
    Hello Brady, Happy to get you all the parts you need so you can head out on your September adventure! And a million thank yous for the pictures. They are always so helpful. From the pictures, I can see you have the MORryde LRE suspension. Since you've already had a spring break and found several loose U-bolts, I think now is the perfect time to refresh the entire suspension while everything is apart. Since you're already running the MORryde LRE system, I recommend the MORryde Suspension...

  • Can I Put The MORryde Suspension Upgrade Kit For LRE Leaf Spring Suspensions 2005 bulldog Trailer
    Hey there, happy to help! The MORryde Suspension Upgrade Kit # MR79ZR can work really well, but you’ll want to double-check a couple things on your trailer first. This kit is designed for trailers that are equipped with the MORryde's LRE leaf spring suspension system with rubber shear springs. If your trailer doesn’t have that, then the better option would be the MORryde Suspension Upgrade Shackle Strap Kit # MR46ZR. That kit is more universal and is a great choice for upgrading your...

  • 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.

    Hello Tom. The MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR79ZR is for trailers with LRE suspension and rubber shear springs. It sounds like this is what you have, so please just confirm that your shackles are the 2-1/4" long (center hole to center hole). If so, this kit will work great for you. It sounds like you are on the right track with the shear springs too. I have included dimensions for the # MR79UR shear spring below so please check to make sure this matches the...

  • Replacing/Upgrading The Suspension On A 2007 Colorado Tandem Axle 5th Wheel With LRE Suspension
    It sounds like you are definitely on the right track here. The # MR79ZR is indeed the correct suspension upgrade kit for your 2007 Colorado 5th wheel with LRE suspension. Moryde makes a fantastic suspension upgrade kit. The heavy duty shackles and wet bolts are highly durable and will last a very long time as long as you keep them properly greased. The shear spring # MR79UR is also correct for this setup. The leaf springs might be a bit more tricky, since you are measuring them under a...

    Thanks so much for the photos they were super helpful. What they show is that you have the MORryde LRE suspension with the shear spring, and the part number you mentioned confirmed that as well.

  • Upgraded Suspension Components for 2016 Jayco Pinnacle 38 FLSA
    You can use 8k springs on a trailer that has 7k axles. You'd just have a little more spring capacity than needed. If the dimensions of your springs are the same as the part # DX74XR springs then you would not need new hangers. Worth mentioning is that even if the dimensions are different you could always cut off your current hangers and weld them back on in the correct location. Everything you mentioned would fit and work great. MorRyde Suspension upgrade kit # MR79ZR Replacement of...

  • Correct MORryde Suspension Upgrade Kit for 2013 Keystone Monatana Mountaineer With LRE4000
    The # MR78ZR kit is designed for the older RE suspension and won't work with your setup. You have the LRE4000 if you have the #20 shear springs. You will still need to replace the rubber shear spring with the # MR79UR. Then you can use upgrade kit # MR79ZR which is designed for the LRE4000.

  • How to Find Replacement Leaf Springs for 2012 Keystone Cougar 27RLS
    The size of the replacement leaf springs on your 2012 Keystone Cougar 27RLS should be the same as what you have now. To be more specific, you need to match the length as well as the axle capacity. Based on the weight of your trailer it looks like you have 3,500 lb axles but I would check the axle tag to be sure. The length is something you will have to measure. The standard is the spring eye to spring eye measurement. You can also use the flat measurement since your leaf springs will...
