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:

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:

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:

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:

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:

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:

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:

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:

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



by:

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



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:

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:

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



by:

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



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.

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.

Great communication



by:

Item is well packaged and arrived on ti me.



by:

Love buying from e-trailer. Good people to deal with.



by:

Our bushings were worn through so it was time to replace. Everything worked just as described.

Great upgrade to the suspension on my 2016 Cougar XLite 29RLI 5th wheel. I've always received great products and prompt service from E-Trailer!

  • 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.

  • Torque For Shackle Strap Bolts on MORryde Suspension Upgrade MR58ZR
    I took a look at the instructions and the correct torque is 50 ft-lbs for the shackle strap bolts on the MORryde Suspension Upgrade Kit for Tandem Axle Trailers w/ Correct Track - 2-1/4" Shackle Straps # MR58ZR.

  • Tandem Axle Lift Kit For Double Eye Leaf Spring Suspension Systems
    While the Lippert Components Tandem Axle Lift Kit is discontinued we do have the Correct Track Trailer Alignment and Lift Kit # RR23QX that will raise your suspension either 1-1/4" or 2-1/4". It will also give you the adjustability to move the axle up to 1/2" forward or back if the axles are out of alignment. Adding a Wet Bolt Kit # MR58ZR(2-1/4" shackles) or # MR98ZR(3-1/8" shackles) is a great add on when you add the lift kit. The wet bolts help the suspension to travel easier through...

  • How Many MORryde X-Factor Crossmember Supports Are Needed For A Tandem Axle Trailer?
    The MORryde X-Factor Crossmember for CRE, SRE, or Stock Leaf Spring Suspension # MR33WR includes one adjustable crossmember. Your existing hardware will be too short due to the extra thickness of the crossmember, so you will need to add # MR58ZR if your current shackles are 2-1/4" long, or # MR98ZR if your current shackles are 3-1/8" long. This will install to the leaf spring hangers, located in-between the front and rear axle. So, for full support, a tandem axle trailer will utilize 3.

  • 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...

    You are right on with the equalizer kit you need for your 42 inch axle spacing, though the correct upgrade kit is going to be different than the # MR58ZR. What you will need is the following: - MORryde 14-3/4" Shock Absorbing Equalizers for Tandem Axle Trailers w/ 42" Wheelbase # MR34AR - MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR The # MR46ZR is correct for the upgrade kit as opposed to the # MR58ZR (which is only for trailers that...

  • 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...

  • Coupler Mounted Bike Rack for a 2020 Keystone Passport SL Series Travel Trailer Reciever
    I have a solution for you but seeing how your factory leveling system spans the entire rear of your 2020 Keystone Passport SL Series Travel Trailer you're not going to be able to go with a hitch. There will be no where to mount one securely enough to support your bike rack and bikes. I recommend the Stromberg Carlson Bike Bunk Trailer-Mounted Bike Rack Carrier for A-Frame Trailers - 2"-100 lbs item # CC-275. This carrier is designed for use with 2" hitch-mounted bike racks that are approved...

  • Length Options for MORryde Suspension Upgrade Kit for Tandem Axle Trailers
    The MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track comes in two different lengths, part # MR58ZR for 2-1/4" or part # MR98ZR for 3-1/8". Please note, the above are for models with the Correct Track system. For standard models you'd simply use part # MR46ZR or part # MR76ZR. The shackle straps are measured from the center of each eye. The 1/4" should not create any issues. These are however standard sizes that most trailers use.

  • Recommended Heavy Duty Shackles for Tandem Axle Trailer
    We do have some more heavy-duty type shackle kits and for that I recommend one of the following from MORryde based off of the length of your shackles: - 2-1/4" Shackles # MR58ZR - 3-1/8" Shackles # MR76ZR The shackles that come with these kits are 1/2" thick so they will be much more durable than your current shackles.

This kit will allow you to replace all your shackles, wet bolts, and bronze bushings included with the Dexter EZ Flex # K71-653-00 in one easy kit.

    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.

    For your application I recommend checking out the Shackle Strap # TRSL225 which is 2-1/4" apart for the bolt holes, has an overall length of 3-1/2" and a 1-1/4" width like what you're looking for. 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.

  • 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...

    Yes the Equa Flex Equalizers part # LC279688 can be used with 5,100 lb axles like what your trailer has. This will also work great with the HD shackle kit part # MR58ZR you are interested in as well. Sounds like you have standard trailer leaf springs as well based on your dimensions.

    You are able to reuse the nuts for your wet bolts. And you are able to use the Road Armor Shock Absorbing Equalizer Kit # LC696740 to replace your current equalizers. The minor measurement difference will not cause a noticeable difference in the height of your trailer. I do typically recommend replacing all the wet bolts when you do change out the actuator as it is typically a good time to do so to clean out any dirt and get fresh parts in. Here is a list of the different kits we have depending...

Once you have this information you can find the correct part in the list I have included below. You can filter them by the length of the shackle straps.

    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...

For your trailer you'll need the following components: MORryde Rubber Equalizers # MR87ZR MORryde Suspension Upgrade Kit # MR58ZR This is not too bad to install yourself assuming you have...

It includes longer bolts for the adjustable mount on the end of your leaf springs. It includes new bronze bushings that you can use to replace your nylon bushings.
