every thing ordered fit perfectly a little labor intensive but job completed in approximately 6 hrs shear springs will make a big difference as the old ones had worn out and were splitting bad on left side not so much on right but replaced both sides and all bushings and new wet bolts and shackles now the suspension is like new as my Montane is 10 yrs old

- MR46ZR

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.

- MR46ZR

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.

- MR46ZR

The rear mounting bolt and the front mounting bolt to the frame are the wrong length! I called but they can’t get me the correct size which is the same size as the shackle bolts to the equalizers

I have spoken with one of our installers and it seems that you will need longer bolts for your application than normal. I see in your pictures that your hangers are a bit thicker than normal. Unfortunately, we currently do not carry bolts that will fit that extra inch or two. I apologize for any confusion, the 3.3750 inches that is on our site is the overall length. I have sent in an update to get that clarified on our site.

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.

- MR46ZR

Easy to install a huge upgrade from the cheap plastic bushings. Glad I changed them out the bushings were wore through and some of the bolts had flat spots shakel holes were oblong trailer has about 15000 miles and is in it's 3 rd season. Read tires were starting to wear funny,hope this helps tightens things up

- MR46ZR

Well made quality product with dimensions I couldn't find elsewhere and easily installed. Only reservation about design is lack of provision for cotter pins for safety to prevent nuts from backing off.

- MR46ZR

Have only put about 4K miles on these parts since I installed them (took about 8 hours and some cuss words) and so far everything is holding up well and a huge improvement over the stock trailer parts. Impressed with etrailer and their handling of my order. Will definitely go to them in the future if needed.

- MR46ZR

Nice product, my shackles were showing some wear so I upgraded to these with wet bolts, now I can grease them

- MR46ZR

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.

- MR46ZR

Install was easier than I thought it would be. Bigtime upgrade over stock shakes as they would not have lasted the next trip! Parts arrived in 2 days. Easy breezy, great piece of mind!

- MR46ZR

I had the Morryde equalizer installed & my mpg improved from 10 mpg to 14 mpg.

- MR46ZR

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.

Thank you for the review and bring this to our attention. It is not our policy to restock used items. Our customer service team should be reaching out to you in the near future.

5 stars for ease of order and delivery of the MORyde3000 and shackles. I plan on installing them in a week or so. Looking forward to taking them out for a ride.

- MR46ZR

poor quality threads on the bolts full of dings and I had 1 strip out with less then [] of torque on it.. had to purchase separate wet bolts to replace the ones that we messed up.

I will have our customer service team reach out to you.

It's nice to have items fit and function as the discription depicts.

- MR46ZR

Awesome customer service when I called with questions about the shipping of my order.

- MR46ZR

Great kit for a DIY project. Straight forward with everything needed but the grease to lube everything which is the user’s choice anyway.

- MR46ZR

Quick easy install, very heavy duty. R ecommended!

- MR46ZR

It looks good, now I have to crawl under the trailer and install it.

- MR46ZR

Nicely packaged and ready to install. Installation went well, had one bolt that would not accept grease. Called Morryde and they are sending me a new bolt. Trip planned will follow up after that on performance.

- MR46ZR

parts look good . but package looks like it was dropped off a train going 80mph. most of the parts were broken out of the vacuum packaging .luckly nothing missing

I will have our Customer Service team reach out to you.
