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.

It has been a year since installed the upgraded parts. I have to say I am 100 satisfied with ALL the upgraded parts.



by:

Got my upgrade kit yesterday along with new springs and Road Armor equalizer. This will be a huge improvement over the stock units i had on the trailer. I want to give kudos to etrailer for the prompt and quality shipping. Everything is great. Also, to @BigTruckBigRV for the invaluable information on the different types of equalizers and parts. His report guided me to etrailer. Finally, and big thanks to Phillip and this guidance and suggestions. I had shopped on the web site and had a pretty good idea of what i was looking for and at. Phillip made a couple of key suggestions and really tied it all together for me. Thanks Phillip.

@Skip Great to hear. Thank you for the update.

Please see attached photo of how this package arrived, the outside box was not damaged at all. This means someone at etrailer really packed it like that and thought it was fine.

I can understand your disappointment in how this was packed. It will be sent to our shipping department for review.



by:

Installed quick & easy , gave it a 4 because I think the bolts should be grade 8 , just my opinion, the straps are heavy duty and the bronze bushings are a must, watch the video before i started to have a game plan



by:

1 star
These bushings have entirely
to much slop
About .030 worth
If my original shackles weren’t busted I would have returned this rebuild kit
As for the curved equalizer 1 star as well
Much thinner castings that my “stock” original parts
And the bushing holes are machined crooked and off center

E-trailer doesn’t want comments on their shipping but my orders in the last couple years has been extremely unreliable
I will probably never use this company again



by:

Good product, wish the kit was available with 7 3/4" equalizers & 3 1/8" straps. have to piece-meal it together. E-trailer was a bad choice through. Should have ordered elsewhere- cheaper and faster for identical kit.



by:

Used with a complete suspension overhaul, with the exception of the axles. Paula was excellent in assisting with the right (4) springs, equalizer, u bolts and this kit. She worked with me over the phone asking the right questions as I measured and rechecked lengths and widths. Got everything right the first time, everything bolted together with a little persuasion.



by:

Heavy duty shackles to be sure. However the quick lube holes on the shackles will not be on the 3 or 9 o'clock position once installed. I don't know if this will be an issue but I've been told greasing is facilitated by having the lube holes in that position.



by:

Did not have long enough shackle bolts to attach to trailer hangers. Called etrailer customer support. They took information and told me they would be calling me back with an answer. It has now been several weeks and I have yet to receive a response. I went to locate trailer shop and they were kind enough to order the correct wet shackle bolt to attach spring to trailer.



by:

I bought this kit to upgrade the suspension on my RV. I installed Road Armor equalizers when I installed this kit and everything worked perfectly together.

The shackles are massive and you get everything you need to completely re-work your leaf spring suspension. The wet bolts are machined perfectly and include locking style nuts - no lock washers needed.

Putting grease into the bolts really quieted down the suspension on the RV. No more low speed squeaking when parking or moving.

etrailer was great to buy from. Their tech support confirmed for me that I could use this kit with the Road Armor equalizers. Their pricing was good and my order was processed quickly.



by:

As many here have said, initial reaction when unboxing these MoRryde shackle kits is surprise at how inadequately they are packaged ,- I took had a box full of loose nuts, bolts, shackles and bushings because the thin plastic broke loose in transit. Nothing damaged or missing just not a great first impression. I did read thru many of the reviews and saw some said to be sure to check that all wet bolts actually allowed grease to flow thru to the bushings BEFORE install and sure enough, one of the bolts did not. Could not get grease to flow. I found the hole at the bushing side of the bolt wasn't drilled far enough. It was easy enough to fix but if I hadn't caught it, one bushing would not have been greased. So, BE SURE TO RUN GREASE THRU EACH WET BOLT AT THE BENCH - DO NOT INSTALL BEFORE CHECKING EACH. If you find one or more not flowing you should be able to quicky solve by drilling those a bit deeper.



by:

These are a very high quality upgrade if you use your trailer a lot, I would definitely recommend this kit if you care about the maintenance on your trailer. The grease ports are what keeps the parts alive and the parts thickness compared to standard shackles is clearly up for those heavy hauls. Absolutely worth the money!



by:

Excellent upgrade to my suspension!



by:

Thank you e-trailer the kit you sent by moRryed worked. Excellent. This what we had from the kit from dune sport in the first kit we bought and as you can see the straps were to short. So anyone putting road armor on your trailer make sure you get 3.125 straps. Sent a picture of the finish but did not load.

Much stronger and should make maintenance a bit easier !

@John We're glad to hear that your # MR76ZR MorRyde wet bolt/shackle kit is working well for you!


by:

This is a really well made kit, everything seems really sturdy. Installed very easily. Have had no problems. I particularly like that it has good grease fittings and grease path that really gets grease everywhere.



by:

Both orders delivered shackle kit took longer to get it was ordered first how ever all perfect fit easy installation thanks



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:

Exactly what was needed and got here very fast! Etrailer is always great with getting us what we need the first time!



by:

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



by:

Just installed today everything went together well. I like that these are grease. Just see how they last compaired the standard shackles



by:

Quality bolts and bushings. Much better than the original nylon bushings that were worn out after only about 15k miles.



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.

Ive put several thousands of miles on my 5th wheel without a problem. Very happy with this product.

This kit has some serious looking shackles. Can't wait to install them on. Looks like an awesome upgrade to my rigs suspension.

  • Availability of 7-3/4 inch Equalizer Kit with 3-1/8 inch Long Shackles
    The lengths of the shackles that come with the equalizer kit part # K71-449-00 that you referenced are 2-7/8 inches measured from hole center to hole center. If yours are currently 3-1/8 inches this change would slightly lower the height of the trailer but it would still work. To match the shackle lengths and also be the thicker style you'd need the kit # MR76ZR with the # K71-655-00 which is cushioned. Or for just a standard equalizer and shackle kit you'd want the # e99ZR.

  • Suspension Upgrade Kit Recommendation for a 2007 Weekend Warrior 23FS Super Lite
    It sounds like you're needing to replace the wet bolts and shackle straps on your suspension setup, and you're wanting to use bolts with grease zerk fittings. For that I recommend checking out the following: - MORryde Suspension Upgrade Kit with 2-1/4" Long Shackle Straps # MR46ZR - MORryde Suspension Upgrade Kit with 3-1/8" Long Shackle Straps # MR76ZR You'll need to measure from the centers of the shackle strap bolt holes to ensure you get the correct length for replacements.

    MORryde does have a suspension upgrade kit that I highly recommend. It comes with 1/2" thick shackles, along with wet bolts and bronze bushings. You will want to choose a kit based on the length of your current shackles. For 2-1/4" you need the # MR46ZR and for 3-1/8" the # MR76ZR. For replacement leaf springs you will need to know your axle capacity along with your spring eye to spring eye measurement. Your current leaf springs will be slightly elongated since they flatten over time so...

  • How To Confirm Fit of MORryde CRE Shock Absorbing Suspension Equalizers for Tandem Axle Trailers
    In order to confirm fit of the MORryde Shock Absorbing Suspension Equalizers for Tandem Axle Trailers you'll simply measure the axle spread on center. If the axles measure 33" apart then use part # MR87ZR but if they are 35" apart then use part # MR27ZR. If you want to add shackle straps and wet bolts, part # MR76ZR is for 3-1/8" long and part # MR46ZR is for 2-1/4" long. If you can inform of which LRE system you have I would be glad to inform of which CRE replaces this.

  • Lift Kit and Wet Bolt Kit for 2019 Dutchmen Voltage 3815
    We do have what you're looking for, but some more information will be required to find the right parts. If your leaf springs run under your axle you can use a flip kit for a lift. Based on your GVWR I'm assuming you have 6,000 - 7,200 lb axles which would have a 3" diameter. If that is the case, you can use the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00. This will raise your trailer by the diameter of the axle plus the height of the leaf spring stack. If your leaf springs...

    The only 3-1/8" shackle kit we carry from Dexter is the # K71-358-00 which is for a single axle trailer. If you are in need of a complete kit for a tandem axle trailer, we recommend the MORryde Suspension Upgrade Kit # MR76ZR. This will come with very similar 3-1/8" HD shackles, bronze bushings and wet bolts just like the Dexter kit. The equalizers are sold separately, and we have many different sizes available depending on what you are needing. We just want to make sure a replacement...

  • Determining The Correct Replacement Suspension Components For A 2018 Keystone Bullet Crossfire 270BH
    To determine the correct replacement equalizers, bushing, wet bolts, shackles straps, etc. you'll need to do a bit of measuring first. The manufacturer designed the suspension to sit in a specific way so that it can roll back and forth so it's important to match the factory sizes. Starting with the equalizer you'll want to measure from the center to center of the shackle strap holes (horizontal) and from center of the shackle strap hole to the hanger bolt hole (vertical).

    Thank you for the photo and dimensions of your 368 equalizer! You can upgrade your leaf springs from 4K to 6K but just keep in mind that it will make the ride quality of your trailer a bit more stiff and the springs need to have the same length as your current springs. Measure from center eye to center eye without weight on your current springs (lift the trailer by the frame to do this) and then choose from the following: 25-1/4" Long - 4K # e57SR (3-leaf) - 6K # e34SR (5-leaf) 26"...

They both work with 8,000 lbs axles so don't worry about the wheel base. I have linked an installation video below.

Although I'm fairly certain the # MR46ZR is the right wet bolt kit, they do not list the shackle size so I recommend measuring. If you have 2-1/4" shackles then this is the correct kit.
