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.


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.


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.


This kit is so much heavier than the original I was concerned that I ordered the correct kit. Thanks to the ETrailer support staff for assisting me and getting the correct kit, the figment was perfect. Installation was very easy.
I’m glad I ordered the kit when I did as the original plastic bushings were already worn out.


Great phone service.. help with solution and product selection.
"How to" video most helpful!
Outstanding product is heavy duity, 3× thicker steele than original shackles.. only negative was delivery time was two days later than promised even though order shipped immediatly... recomend UPS rather than USPS..

@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.


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


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


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.


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.


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.


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.


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.


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.


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!


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.


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.


Excellent upgrade to my suspension!


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.


Much stronger and should make maintenance a bit easier !



Holding up well ! Easy to grease and maintain .

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


Very happy with what I purchased Trailer tows great


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


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


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.


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

  • Can Plastic Bushings In Curved Equalizer TREQ356 Be Replaced W/ Bushings In MORryde Kit MR76ZR?
    You have a pretty good game plan! The Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 6-1/8" Long - 9/16" Center Hole # TREQ356 you mentioned will work perfectly to replace your current 6-1/8" long equalizer and will be an exact replacement, and the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR will be an exact replacement for your current hardware while giving you bronze bushings and wet bolts.

  • Picking Out Wet Bolt Shackle Kit for MORryde CRE3000 Kit on Trailer Suspension
    The correct wet bolt/ shackle upgrade kit for your MORryde CRE/3000 kit will depend on the length of your current shackle links, measured center hole to center hole. For 2-1/4 inch shackle links, use # MR46ZR or for 3-1/8 inch shackle links, use # MR76ZR.

  • Recommended Equalizer and Replacement Shackles for a 2019 Grand Design 2850
    Yes, it is. However since you have a 35" wheelbase you're going to want the MORryde Shock Absorbing Suspension Equalizers item # MR27ZR. These are specifically designed for trailers with a 35" wheelbase. They are made for 8,000 lbs axles so you will be good on the weight. The MORryde Rubber Equalizers for Tandem Axle Trailers item # MR87ZR are for a 33" wheelbase. The only reason you should go with these over item # MR27ZR is if your current equalizers are the same dimensions. I have linked...

    When choosing an upgraded equalizer like the Road Armor Shock Absorbing Equalizer Kit - Tandem Axle - Qty 2 # LC696740 you want to choose a kit that is as close as possible to your current equalizer width. The # LC696740 measures 6" from center to center across. I recommend measuring your current equalizers in order to make the best choice. If your current equalizers share the same 6" measurement, or are very close, then this kit will work well for you. This is the only size available...

  • Troubleshooting Grease Only Going Through Grease Zerk and Not Into Wet Bolt On MORryde # MR76ZR
    It sounds like you may have one of 2 things going on inside your wet bolts. I have seen some instances where some particles/dirt get inside the wet bolt and clog the weep hole the grease is allowed to pass through. You can remove the bolts not taking any grease and try using a compressor air tool to blow out any debris that may be stuck inside the bolt. Be sure to blow from the weep hole out once you remove the grease zerk from the end of the bolt. You can also use some brake cleaner or...

  • Is 1/4 Inch Height Difference Okay For Use With E-Z Flex Equalizers
    Hi Sam, Good question, and the mere 1/4 inch difference in the height is not going to have any type of negative effect on your trailer so you can 100 percent use the E-Z Flex Equalizers # K71-655-00. These are a smart choice as they'll make a nice difference in how your trailer rides due to its rubber cores absorbing bounce and shock.

  • 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.

  • Recommended Equalizer Upgrade for 2011 Keystone Springdale Travel Trailer
    The best option for an equalizer upgrade on your 2011 Keystone Springdale is the one that matches the dimensions of your current equalizer. The # LC696740 measures 6" across, which is the most important measurement, and is 3-1/2" tall from the line between the center of the left and right eye. See the diagram below. If your measurements match the Road Armor, or are very similar, then this would be the best choice. If you have different measurements feel free to reach out with what you...

  • Replacement Axle, Springs, Wet Bolts, Equalizers, and Brakes for Tandem Axle Trailer
    I'll start by covering the axle since this information is important for other components as well. The first thing you want to do is identify your axle capacity. Since this is a tandem axle trailer and you're thinking 7,000 lb capacity you probably have tandem 3,500 lb axles. Take a look and see if you have the capacity listed on axle tags. If not, you can measure the diameter of the axle. A typical 3,500 lb axle has a 2-3/8" diameter. If you find that you have a 3,500 lb axle, and your...

    Yes, the Road Armor Shock Absorbing Equalizer Kit - Tandem Axle - Qty 2 item # LC696740 will work on axles that are 33" center to center. These equalizers measure 6" from center to center of the two center bolt holes as shown in the included diagram. As long as your current equalizers are the same length these will be a direct replacement. These equalizers work with 3,500 lbs - 8,000 lbs axles.

  • Upgrading To a Shock Absorbing Suspension Equalizer With A 42" Wheelbase Tandem Axle Trailer
    It is a good way to measure for a replacement equalizer, but I always recommend verifying the equalizer length as different springs will allow for different length equalizers. As you have a 42-1/2" spacing you most likely have the 14-3/4" equalizer. This is the measurement from the center of front bolt eyelet to center of rear bolt eyelet on your equalizer. I recommend the MORryde 14-3/4" Shock Absorbing Equalizers for Tandem Axle Trailers w/ 42" Wheelbase # MR34AR. This CRE3000 equalizer...

    It sounds like you want an upgraded equalizer to replace your Dexter 12-142 equalizers. I recommend the # LC314336 you were looking at for a replacement. This matches the length of your current equalizer, which is the most important factor when choosing a replacement. The Equa-Flex will help absorb road shock and improve your ride while towing your trailer. For shackles and wet bolts, I recommend the MORryde Suspension Upgrade Kit for Tandem Axle Trailers.

MORryde has wet bolt kits for use with the CRE3000 kits like with the part # MR46ZR which has shackles that are 2-1/4 inches long and part # MR76ZR which comes with shackles that are 3-1/8 inches. These kits also come with bushings, shackles, and nuts.

The U-Bolt Kit # CE23002 is a great upgrade to the uncoated u-bolt you currently have.
