Along with replacing the springs on my tandem trailer I upgraded the equalizers shackles and installed with the wet bolt hardware. I am very satisfied with the quality of components. etrailer’s customer service and quick delivery will continue to be my first go to when I need parts.

Since rebuilding the suspension on my 5th wheel trailer, we have put 4500 miles on it. With the new springs and equalizers installed, my trailer does tow much better. Thanks to the customer service at etrailer we have enjoyed vacationing much better.



by:

After Ashley and others helped in an emergency situation overnighting another package of MORryde wet-bolts/shackles, I was able to complete the installation along with a Correct Track Alignment/Lift Kit. This was a JOB with 2 dudes hard at it to get the wet bolts/shackles on with the alignment and lift kit, getting the axles aligned just in time to hit the road for our long scheduled vacation... I was missing 2 longer wet bolts for some reason? I have to to tell you it was FRANTIC at the end, since I was doing my own work luckily with a friends help. It's a 2 person job.But ETRAILER came through! Thank you gals and guys! Rated a 4 only because there weren't enough longer bolts that were missing. ETrailer sales and tech are a 5!

Took another 1000+ mile trip recently and the trailer tracked fine, no noticable tire wear as if out of alignment and the lift kit has solved my tire rubbing on the camper upper wheel well with hard jiltssuspension travel.



by:

we just took the trailer with the MORryde suspension up grade on a 10,000 mile trip to Alaska & back over some very rough roads with no problems.



by:

One is the best purchase's I have made. No more stress as I'm going down the road with things banging in the 5th wheel.

Easy installation as long as you have the skill and tools to do it safely.



by:

Great to have grease-able suspension it really helps the wear and tear on your camper, well worth the money .



by:

So far so good. Definitely seems to minimize noise, which I’m hoping is also reducing wear and tear. Tricky at first to get grease to flow all the way through the bushings, definitely need to take some weight off the springs to do so. What I did was drive one axle on blocks, then take all the weight off the other axle with a jack to get to the grease to flow properly. Maybe there’s a better way to do it, but this worked for me.



by:

From what i have delt with in the past from other companies, customer service at e-trailer is the best in the business. Adam that took my order was pure proffesional and awesome to deal with. Great company, will be purchasing alot more from e-trailer...thanks again Adam....



by:

The kit supplied only Qty 2 of the correct length wet bolts when my particular application requires Qty 4. The four that came in the kit are too long for my front and rear axle drop down trailer brackets. As such, I was only able to install my new equalizer and wet bolt hardware kit one side of my trailer today. As you can imagine this is somewhat frustrating because my trailer is not located close by, I had to bring all the tools with me to get it done.

Here is a picture of the used bolt length that I will need a total of four more sent to me at your earliest convenience. The kit provided only two of the correct length bolts, which I utilized where the equalizer mounts to the drop down bracket.

Hopefully other customers aren’t having this same issue.



by:

This kit was an awesome upgrade from what I had and maintenance will be easier now. Not too hard to install the new bushings.



by:

Took 3 weeks to ship with promise of upgraded shipping only to take another 3 extra days to arrive and damaged when it finally did arrive

Gosh that is frustrating, I am so sorry! I will make sure our customer service team reaches out to you about this.



by:

I received this item and the plastic wrap inside box was all torn apart and items were all loose. All were there, but upon inspection I noticed that two of the bolts were not the right size for 3rd generation Correct track alignment kit. The old Alignment kit required 2-7/8 inch wet bolts at the center hangers. The 3rd gen kit requires 3-3/8 inch wet bolts at the center hangers. you can see in the photo that 2 bolts are shorter, they should all be the same length.



by:

The wet bolt kit had four bolts that were a half inch to long. Other than that everything was great.!



by:

Perfect fit. Original plastic bushing were destroyed. The new brass bushings that you can grease were a great upgrade for our 2016 Bighorn 3160EL.



by:

The upgrade quieted the axles down when maneuvering the trailer around. No more banging or squeaking from the suspension.



by:

installed MORryde 2-1/4 inch shackle straps with MORryde 14-3/4 inch Shock Absorbing Equalizers (MR34AR). The camper rides much better.



by:

The product looks great. Haven’t installed it yet but I’m sure it’s going to be a great improvement.



by:

After 1 year and several trips…awesome!!! However I also installed a”wet” bolt kit and shocks…. W-H-A-T a difference!!! All from etrailer. All trailers should come like this!! 2021 271RL Salem Hemisphere



by:

This kit should have 6 bolts @ 2 1/4" for the leaf ends and equalizer hanger and 8 longer bolts to accommodate the thicker shackles. Can with 12 longer bolts and 2 shorter. Had to cancel my memorial day trip because of it.

Customer Service will contact you.



by:

The kit fit perfectly. The hardest part was replacing the brass bushings in the Equalizers. With that done the rest went quickly. Worked great with the Correct Track.



by:

Smooth ride and more flex over rough terrain …. No wear and easy to maintain



by:

Great product



by:

The kit includes bolts that are too long for leaf springs. The hanger bolt and shakles are correct length. They assume the hangers for the leaf springs are thicker metal like the replacement shackles. Now I need to buy 4 more bolts at $[XX] each and another $[XX] in shipping. Don't buy the kit!



by:

The kit came with two bolts that didn't belong in the kit and couldn't use do to being the wrong size.

Etrailer Expert

Well that will not do! I will have our Customer Service team reach out to you to ensure you have all the correct sized bolts.



by:

I am completely satisfied with this product. It has far exceeded my expectations. The install was painless.

Great communication

  • Replacement Bearings for a Dexter 7,000 lbs Axle and Wet Bolts for a Morryde CRE 3000
    I sure can! To replace the bearings in your 2023 Grand Design with Dexter 7,000 lbs axles you will need the following parts: Inner Bearing - Replacement Trailer Hub Bearing item # 25580 Outer Bearing - Replacement Trailer Hub Bearing item # 14125A These part numbers are for the individual replacement bearings. We do have options for complete kits that also include the races and grease seals, however there's two options for grease seals on Dexter 7,000 lbs axles. You will want to use...

  • Recommended MoRryde Equalizer and Replacement Shackles for a 2023 CrossRoads Sunset Trailer
    Thanks for the measurements and additional information! To determine which MORryde Equalizer you need you'll want to measure the distance at the bottom of your current equalizers from the center to the center of the bolt holes. The MORryde item # MR87ZR measures 6-1/2" and is for 33" wheelbases. The MORryde item # MR27ZR measures 8" and is for 35" wheelbases. I have linked a couple of diagrams below.

  • Can I Use MORryde Suspension Bolt Kit with Road Armor Equalizers?
    You can definitely use the MORryde suspension bolts if that's what you're wanting to use. The correct kit depends on what your trailer is currently equipped with and how long your shackle straps are (see attached photo of where to measure). If you have the Road Armor and Correct Track 2-1/4" Shackle Straps - # MR58ZR 3-1/8" Shackle Straps - # MR98ZR If you only have the Road Armor 2-1/4" Shackle Straps - # MR46ZR 3-1/8" Shackle Straps - # MR76ZR We always recommend when you do something...

  • How To Select The Correct MORryde AllTrek Equalizer For a Tandem Axle Trailer
    The best way to find the correct replacement for your equalizer is by measuring the distance from the front shackle hole to rear shackle hole on your current equalizer. The 33" AllTrek # MR89DR has the holes spaced 6-1/2" on center while the 35" AllTrek # MR29DR spaces the holes 8" on center. While the MORryde qualifier is very helpful I find that measuring is best since different trailer manufacturers do not always follow the same practices for welding on the spring hangers and setting...

  • MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers With 35" Wheelbase
    We do carry the MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers # MR29DR. This is going to be their 35" wheelbase version which is going to be 8" from center of front shackle mounting hole to the center of the rear shackle mounting hole. I recommend pairing this with one of their shackle kits.

  • Recommended Replacement Equalizers and Wet Bolt Kit For a 2014 Heartland Landmark Savannah 5TH Wheel
    With the recent addition of the MORryde AllTrek 4000 Equalizers # MR29DR I feel these are now the best option. These equalizers provide up to 4" of travel with axles up to 8,000lbs. Be sure to pair this with one of the shackle kits listed below. You will need to identify if you have Correct Track suspension(adjustable axle hangers) and what the length of your straps are from center to center on bolt holes.

  • Troubleshooting Lower Suspension Height On a 371 Fuzion 5TH Wheel Toy Hauler With MORryde CRE3000
    It is normal for the rubber to push out of your MORryde Shock Absorbing Suspension Equalizers # MR27ZR the way it is. The main issue I see is your Shackle Strap # TRSL313 is wearing out. I can see a bit of the hole on the top left strap which means the holes in the strap are being elongated. I recommend replacing these immediately with one of the following kits.

  • What Shackles Do You Recommend For My Equa-Flex Cushioned Equalizers, Part # LC279688
    Since you are going with a slightly bigger equalizer, the Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 6K to 8K, part # LC279688, you will go with a smaller shackle strap. The MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track - 2-1/4" Shackle Straps, part # MR58ZR, is my recommendation. This change will minimally affect the height of your toy hauler, if they affect it at all. I have included a product description link and video review links below.

  • MORryde Cushioned Equalizer Kit for 2017 Keystone Outback Ultra Lite 278URL with 33" Wheelbase
    The MORryde Cushioned Equalizer kit part # MR87ZR is the correct kit for your 2017 Keystone Outback Ultra Lite 278URL based on your axle capacity and wheelbase. Then to compensate for it replacing your shorter width equalizer you'd want to go with the shorter shackle kit part # MR58ZR which has shackles that are 2-1/4 inches long.

  • Cushioned Equalizer Recommendation for Trailer with 33 inch Wheelbase
    For a trailer like your 2017 Shadow that has a 33 inch wheelbase the best cushioned equalizer upgrade is the MORryde ALLTREK 4000 part # MR89DR which is only option that has vertical and horizontal cushioning. To upgrade your shackles you'd want the part # MR76ZR for if you need 3-1/8 inch shackles or part # MR58ZR for if you need 2-1/4 inch. This comes with new bushings, wet bolts, and heavy duty shackles.

  • Selecting the Equa-Flex Cushioned Equalizers For a Forest River Cherokee Artic Wolf 23MLE 5TH Wheel
    You will want to use the Equa-Flex Cushioned Equalizers # LC279687 on your Forest River Cherokee Artic Wolf 23MLE 5th wheel. These equalizers are much closer to your 6-1/8" spread at 5-1/2". They are also designed for the lighter axles you have under your 5th wheel since they were designed for axles with individual capacities ranging from 3,000-6,000lbs. The Equalizers # LC279688 you found are not going to work correctly as the 7-1/2" bolt centers are much more than the difference above...

  • Can I Lift One Side of My Trailer at a Time to Install New Equalizers?
    Yes, you can install the MORryde Shock Absorbing Suspension Equalizers for Tandem Axle Trailers w/ 35" Wheelbase - 8K item # MR27ZR by lifting up one side of the trailer at a time. You don't have to have sides of the axle off of the ground at the same time. Since you're swapping out equalizers you will want to change your shackles too.

  • Availability of 2-1/4" Heavy Duty Shackle Straps
    I do have a solution, but the heavy duty shackle straps that come with the # MR58ZR are not available without the rest of the kit. For equivalent shackles you can use the Replacement Shackle Strap for E-Z Flex Heavy Duty Rubber Suspension System by Dexter Axle # 018-024-01. However, depending on the cost you may be better off purchasing an entirely new kit and not the individual shackles. It is also worth noting that the # MR58ZR is for trailers with Correct Track installed. If you do...

    Yes, the MORryde Suspension Upgrade Kit # MR58ZR does include wet bolts for the front, rear and center hangers as well as the the wet bolts for the shackles. Do be sure you have the correct track style hangers as this kit has the longer bolts those hangers require. If you do not have correct track hangers you want to use the Kit # MR46ZR as it has the shorter bolts for standard hangers. I recommend using the Grease # L11390 with a grease gun like the # L30416 which makes it easier access...

  • Replacement 2-1/4" Shackle Strap Recommendation

We don't carry the TPU5212 kit but from what I'm seeing it looks like a whole kit so for a whole replacement kit I recommend the MORryde Suspension Upgrade Kit # MR58ZR which comes with bolts, shackles, and bushings for a tandem axle trailer.

  • Recommended Equalizer Upgrade For a Tandem Axle Trailer With 5-3/4" Wide and 2" Tall Equalizer
    I recommend installing the MORryde Rubber Equalizers # MR87ZR on your trailer. This equalizer is slightly longer and taller than your current equalizer but will still work with your suspension. We have either the MORryde Suspension Upgrade Kit # MR46ZR which fits with standard hangers or the Correct Track Kit # MR58ZR which is for trailers that have adjustable hangers. Both kits use shackle straps which are 2-1/4" on center. This is probably the size you have as thinner shackle straps tend...

While the length does not have to match exactly you will want it as close as possible to maintain your current ride height.

  • 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...
