Real stout, should last a long time, great upgrade, should help long travels better, I added a lippert suspension at same time. Takes quite a few different tools. But not a super hard job ,if you have a few of the right tools and mechanical know how to.

Bought these to replace existing shackle straps on my travel trailer that had warn dangerously low. These shackles were twice as thick as what was on the trailer at delivery. Very easy to install (save some time and make sure the ground is level) and don’t forget to grease!

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.

etrailer customer service is second to none! I had ordered the wrong size suspension kit and they were quick to get me the correct version I needed. These are much beefier than the ones that came with my travel trailer. Thank you etrailer!!!

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.

I had the SAME issue as a prior reviewer had. The outer spring bolts are too long for the frame connection. Each of the 4 bolts are 1/2" to long. I was forced to temporarily shim with washers. They need to correct this issue!!!

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.

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.

It was not hard to install the up grade kit, if I had better shop equipment to do the job I could have it done a little quicker. The grease fittings will not take grease I'm going to get new grease fittings and try grease it again, other wise this upgrade kit should out last the 5th wheel camper.

This is WRONG kit for anything without Correct Track system on trailer. For Coachmen Freedom Express trailers, you will need MR46ZR, which has the correct bolts for your job. Went 2 rounds with Customer Service, on why their system would not give me this correct info. Got no where and cost me extra $xxx to complete the job, by having MORryde over night the 4 correct bolts I needed. I will not ever be ordering from etrailer again.

This kit is designed specifically for tandem-axle trailers with Correct Track alignment and lift kits. You will also want to make sure to measure your shackle strap length from center of hole to center of hole to make sure its 2.25 inches and the bolt hole diameter being 0.5625 inches.

I would have given these the highest rating because the product is excellent. The reason for just an average rating is solely because of the customer service or rather lack of customer service. I placed the order for this and 2 additional items to replace the entire suspension on a Passport 3350BH. All items were in stock when order was placed on 1/31/2022 with a delivery date of 02/03/2022. There was a snow storm on 02-03 which delayed the item to the following week which is understandable. However it continued to be delayed until the following week. After my first call I was told the storm had caused a delay. I asked why my order was in a gathering stage for days and then changed to back to order accepted, only response was the snow had slowed them down. After another week of no order, I sent 2 emails with just a standard response of blaming a snow storm 2 weeks prior. I asked several questions on my order which were never answered, I’d have to assume that they just didn’t care to answer or it’s a general email they send to everyone. Long story short the order came on 02/19 which is completely unexceptionable based on a 3 day original ship date. Hard to explain to a customer that a snow storm that we had as well pushed the ship date out 16 days on in stock items.

My suspension squeaked horribly before installing this kit. I installed Lippert Road Armour Equalizer at the same time.
I was surprised to find two nylon bushings worn through completely and all the others in poor condition. Also one link so badly worn I don’t think it would have lasted the season. I few others were in bad condition. Didn’t expect that for a 2018 Unit with what I thought to be low mileage.

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.

- Selecting The Correct Cushioned Equalizer and Wet Bolt Kit For a Grand Design 2800BHThe Lippert Equa-Flex # LC145546 is the closest cushioned equalizer from Lippert to fitting your Grand Design 2800BH. This particular kit is rated for 5K-8K axles. The MORryde CRE3000 # MR27ZR is going to be the best option for your camper. While this is rated for axles up to 8K all of the CRE3000 equalizers carry this same weight capacity. Do understand the different constructions for these equalizers mean while they may look similar they actually operate differently and since the Lippert...

To find the right MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track you will need the center to center bolt hole measurement from your current shackle straps.

The easiest way to determine what size shackle straps you need is going to be to measure yours. The shackles on the MORryde item # MR58ZR measure 2-1/4" long and the shackles with item # MR98ZR are 3-1/8" long. You'll want to measure from center to center of the bolt holes as shown in the included diagram. Which ever one is closest to what you currently have is what you will want to go with. How did you decide on the MORryde Shock Absorbing Suspension...
view full answer... - Replacement Leaf Springs and Cushioned Equalizer for 2017 Reflection 303RLSHey Harlan, since you have a 35 inch wheelbase you can use the CRE3000 kit part # MR27ZR but you will need to go with a shackle kit that is shorter than what you have now. For that you'd want the part # MR58ZR. These are 2-1/4 inches long. Then for leaf springs the part # e34SR that you referenced would be the correct ones to go with as well. This comes with wet bolts as well.

To replace your 13-144 equalizers, I recommend the Dexter E-Z Flex Suspension Kit item # K71-653-00. Aside from the cracked rubber these will be identical equalizers to your current ones.

To upgrade your current equalizers to ones that dampen road shock, I recommend the MORryde Rubber Equalizers for Tandem Axle Trailers item # MR87ZR. They measure 6-1/2" from bolt hole to bolt hole and are 3-1/4". They're a bit shorter but that won't negatively affect the movement or height of your suspension. These cushioned equalizers will help to extend the life of your suspension components by absorbing the harsh road shock and reducing back and...

The correct MORryde AllTrek 4000 is the part # MR29DR for your 2024 Grand Design 2903RL and then for the X-Factor crossmembers you would then want the part # MR33WR as well. You would be able to use an X-factory for each hanger like you asked about too so you would want a quantity of 3. Since you'll have everything apart it would be a great time for a new shackle and wet bolt kit which for that you will want the part # MR58ZR which comes with 2-1/4...

- Will MORryde Suspension Upgrade Kit MR98ZR Work With Road Armor Equalizers?As long as your trailer has the Correct Track and 3-1/8" long shackles measured center to center of the holes the MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track - 3-1/8" Shackle Straps # MR98ZR will work just fine with your Road Armor Equalizers. If you have Correct Track but have short shackles you will need the # MR58ZR with 2-1/4" shackles instead. Now if your trailer does not have the Correct Track you will need either # MR76ZR if you have 3-1/8" shackles...
view full answer... - Cushioned Equalizer Recommendation for Trailer with 33 inch WheelbaseFor 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.
view full answer... - Best Trailer Suspension Cushioned Equalizer Recommendation for 33 inch WheelbaseHey Joe, long time no see haha! So if you wanted the best cushioned equalizer for a 33 inch wheelbase the MORryde Alltrek 4000 kit part # MR89DR would be what you'd want. This is only option that has vertical and horizontal cushioning so it's my favorite to recommend and what I would install on my RV. Then for a heavy duty shackle and wet bolt kit the part # MR58ZR would be what I would recommend. With this you'd be set with everything you need.
view full answer... - Lippert Road Armor Equalizer and MORryde Shackle Strap Replacement KitsHey Dan, thanks for reaching out! The Road Armor Kit # LC696740 is a great upgrade to your current equalizer system, but I do recommend referencing the attached dimensional photo to make sure it lines up well with what you already have. When it comes to the shackle strap kits, you'll want the MORryde # MR46ZR which replaces a standard system. The other MORryde kit, part # MR58ZR, is designed to work with a suspension system using the Correct Track system, which according to your photos,...
view full answer... - Can Both MORryde Suspension Upgrade Kit Shackle Strap Lengths Be Used With MORryde 3000Hi Hallzy; the # MR46ZR and # MR76ZR can both be used with the MORryde 3000. The 3-1/8" might get you a little height but at the cost of potentially throwing off your suspension geometry like I mentioned before. If you want to risk throwing off other components and adding increased wear that is up to you but I still recommend adding taller hangers. If you really don't want to cut off and weld on taller hangers you can use the Correct Track # RR23QX which will raise the trailer 1-1/4"...
view full answer... - Which MORryde Cushioned Equalizer Fits Freedom Express 248RBSHey Alan, the two MORryde part numbers you mentioned are correct for your Freedom Express 248RBS. For your 42 inch wheelbase you would need the part # MR34AR for the correct size cushioned equalizer and then the heavy duty shackle kit part # MR58ZR is also the correct kit for that as well. At this time there isn't a Road Armor version of cushioned equalizer that matches what you need but these MORryde equalizers will work great so that would be what I would recommend. Is your ride quality...
view full answer... - Can MORryde Cushioned Equalizers Replace TREQ104 in 2020 Winnebago Trailer 2401RGHey Dennis, yes the MORryde CRE3000 part # MR87ZR that you referenced will replace the # TREQ104 equalizers you have now as the dimensions are close enough. I would recommend going with a slightly shorter shackle strap to help offset the dimensional differences though. How long are your current shackles? We have the shorter length available with the part # MR58ZR which are 2-1/4 inches long.
view full answer... - Recommended 2-1/4" Shackle Straps You want to get as close to the same size as possible when replacing your shackle straps. We don't have anything closer to a 1-1/2" center hole spacing than the 2-1/4" MORryde Suspension Upgrade Kit item # MR58ZR you ordered. The only concern I would have is additional play and more movement in your suspension or that's a typo because I have never heard of shackle straps that small.
view full answer... - Recommended Equalizer for a 45" Wide Wheelbase Hey Mike! I am sure we have an equalizer that will work. It's easier to find a replacement set if you match up the dimensions of your current equalizers. We have the MORryde 14-3/4" Shock Absorbing Equalizers for Tandem Axle Trailers item # MR34AR, that measures 14-3/4" center on center from the outer shackle bolt holes. It is 3-1/4" tall from the shackle bolt hole to hanger bolt hole as shown in the picture below. If you could get me the same measurements off of your current equalizers,...
view full answer... - Replacement Shackle/Wet Bolt Kit for MORryde CRE/3000 AxleThe correct wet bolt/ shackle upgrade kit for your MORryde CRE/3000 axle 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. If your suspension uses the Correct Track alignment/lift kit, use # MR58ZR for 2-1/4 inch links or # MR98ZR for 3-1/8 inch shackle links.

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.

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.
