I had a leaf spring break on my travel trailer and had some difficulty finding a local dealer for the parts. After doing some google searching, I came across etrailer. I matched the spring size and weight capability with one on etrailer and they shipped it super fast. I also ordered the suspension upgrade kit to go along with the new leaf springs. Ordered on Saturday and got it on Wednesday. I will be coming back to etrailer. Thanks for helping me get my camper back on the road.

This is a very well put together kit. Fairly easy to install. It’s nice that the bolts are already seated into one side of the shackle. I will definitely buy this kit for my other trailers. I highly recommend this kit. Just make sure you grease them once and while.

Fantastic Shackle Upgrade. The Shackles themselves are probably two times as thick as the original. The Greaseable Zirk fittings with brass bushings make it easy to keep the shackles properly lubed so they dont grind down like the original hard plastic bushings. I'm frankly amazed the originals didnt break thro0ough the shackles. But I have zero worries with this new kit. We also paired this with the Moryde CRE-3000 hanger upgrade, which makes the trailer ride much smoother.

Improved the ride of my trailer tremendously!! Stuff is where I put it when I arrive. Was hoping for a lift out of it but got less than 1/2”. The ride quality is enough for 5 stars. Very little chucking now.

by:

Disappointed that I received a repackaged part. I feel I should have been told that it we a returned part before it was delivered to me. It had grease on one of the shackles. And another shackle already has rust on it. Looks like it will be a very good upgrade to my toy hauler.

Very easy install...But use two floor jacks....I used three bottle jacks and two nylon ratchet straps ...Really glad I did this because both front shackel straps were worn oblong and loose...

The upgrade kit installed just as advertised. Only minor issue was the internal packaging was poor and all the parts were loose and banging around in transport. A few bolt threads were nicked and required some cleanup



- MR46ZR
by:

This kit is fantastic! So much better quality than the factory bolts, shackles and cheap plastic bushings... The shackles are twice as thick! I did find that filing down the aggressive knurled surface on the bolts some & applying grease to that area helps to install the bolts easier if they are too tight in your frame hanger brackets. Take your time and work smart and safe!

You are the best. You worked with us and were on the phone for at least 30+ min and did not even feel rushed to get me off the phone. You had what we needed and was here in 2 days. I'm sure when people call and get a girl on the phone they are probably thinking she is not going to be much help but that was the farthest from the case. You go girls!!!

Ask the Experts about this MORryde Trailer Leaf Spring Suspension



  • Could MORryde Shackle Upgrade Kit MR46ZR Fit 2011 Arctic Fox 23-5
    While I can't for sure promise that the Suspension Shackle Kit part # MR46ZR fits your Arctic Fox I would be willing to bet a large amount of money that it would since you have the standard 1-3/4 inch wide springs which are basically always 9/16 inch diameter like what this kit was designed for. So I'd feel very confident recommending this kit for your 2011 Arctic Fox 23-5.

  • Which MORryde Suspension Upgrade Kit For 2-5/8 Shackle Straps
    Between the two kits, the better option for replacing your 2-5/8" shackle straps is the version with the shorter 2-1/4" shackle straps, which is the following part number: - MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR This will lower your trailer ever so slightly, but still allow enough room for suspension travel. Going with longer shackle straps like the other kit has will result in more movement and travel with your suspension, which can lead to suspension components...

  • What is the Overall Length of the Bolts in the MORryde Wet Bolt Kit with 2-1/4 Inch Shackles
    Typically a suspension bolt will be measured by the shaft of the bolt not including the head, since the head of the bolt isn't used in mounting the springs. The shackles are 3-3/4" long x 1-1/2" tall overall and the bolt holes are 2-1/4" center on center. I've also included dimensional drawings of the bolts for you to check out, but the shorter bolts are 3.2285" in total length and 2.8755" from the head of the bolt to the end; the longer bolts are 3.7285" overall and 3.3755" from the head...

    It is possible that the MORryde Shocking Absorbing Equalizers # MR27ZR and Wet Bolt Kit # MR46ZR you were looking at will fit your 2020 Grand Design Reflection 337RLS, but the only way to be sure will be measuring what is currently installed on your trailer.

  • How Do I Measure Axle Spread for Upgrading The Trailer Equalizers?
    Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this harder to determine. You can also measure from common points in reference to the axle. Such as the front of the front axle tube to front of the 2nd axle tube or front of front tire to front of rear tire. If you do that you will want to be sure...

    The MORryde Rubber Equalizers # MR87ZR are most likely the correct ones for your 2003 Fleetwood Wilderness. The important part to measure is the equalizer itself. The MORryde is 6-1/2" on center from the front shackle bolt to the center of the rear shackle bolt. The height is 3-1/8" from the equalizer mounting bolt to the center line of the shackle bolts.

  • How To Determine Correct Wet Bolt/Shackle Upgrade Kit For Tandem Axle Trailer
    I can help you figure out how to determine the best option for a wet bolt/shackle upgrade kit, though in order to determine the correct one you will need to take a quick measurement of the shackle straps on your Jayco Jay Flight. The reason for that is these kits aren't specifically designed for any trailer, so to ensure the best fit you want to get the kit with the same length of shackle straps. There are a pair of options for you, depending on the length of your shackle straps: - 2-1/4"...
