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




by:

I had worn out my original shackles (nylon bushings, dry bolts, thin shackles) and ungraded to wet bolts, brass bushings, and thick shackles. I ran into a problem when I discovered that the non-shackle bolts supplied were too short for my Correct-Track system. I used the old (dry) bolts to complete the job.




by:

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.




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.

Excellent upgrade! My puma unleashed toy hauler really needed a suspension upgrade. Makes a huge difference on rough roads and the wet bolt system was a very nice upgrade. highly recommend this product.

by:

The wet bolts were easy to install. No issues. The hardest part was removing the old bolts from the hangers. Although they were expensive, I feel pretty good about the purchase. TIP: I was able to remove the nylon bushings and install the new brass ones at the same time. The new ones pushed the old ones out in the same step.




by:

Arrived on time. Parts seem very heavy duty (see comparison to old picture). I'm a safety freak and I'm confident this kit will provide extra protection while pulling my rig. The original hangers and bushings were completely worn out and bolt holes were elongated (see picture). I'm hopeful that the grease-able hanger bolts will extend the life of these parts.




by:

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.




by:

Crazy Awesome kit. Much stronger than stock. Replaced bad bushings and provided greaseable bushings and pivot points. This will always be my first RV upgrade if I get another trailer. Original shackles fell apart after 5,000 miles and caused uneven tire wear. New shackle kit fix that issue also.




by:

Terrific upgrade. Our fifth wheel is ten years old. When we saw the condition of the old shackles after the MORryde shackles were installed we knew this was a good decision. Furthermore, with the ability to grease the wet bolts annually we know they will last a long time.




by:

All the MORryde components we added work well with the upgrade to two (2) 8000 Lb axles and disc brakes on our NuWa HitchHiker II. Particularly, the three (3) suspension crossbraces added a great deal of stability when turning and backing up.




by:

The bolt kit arrived promptly, as is almost always the case with etrailer products, which I appreciated. The packaging however was of poor quality. The packaging inside the box had broken open and the bolts and nuts were loose everywhere inside the box. The box had also been damaged and I thought for sure there must be some parts missing. Thankfully, after getting everything sorted out, I could see I had the same number of bolts and nuts, so I thought I must have all the parts. I didn't contact etrailer about the substandard packing because I thought all the parts were there, and after all I don't think the seller has a great deal of responsibility in how the the actual shipper smashes up the shipping boxes. The only thing I was shocked about was that there were no instructions. ZERO. I realize it's a pretty straight forward process, But, a few basic instructions would have been helpful. And, after watching a few [online videos], there are plenty of 'helpful hints' that could have been included in the package. After laying out all the loose pieces and figuring out where everything goes, it's fairly straight forward (watch a few [online videos] first, and I don't recommend the one from Morryde, they edit out a couple critical parts the are a pain in the butt to do). I ordered the bolt upgrade as well as the Morryde SRE-4000 suspension with the cross support bar. The box that came a couple days later with the SRE-4000 and cross bar was in perfect shape, had all the contents, but again ZERO instructions. Watched a couple more [online videos] and figured it out. And just FYI, all the parts did NOT fit my Forest River 2916-G Toyhauler. The small 3" bracket plate that goes behind the trailer bracket that holds the new cross piece support bar is too short for that trailer frame. It's not a huge deal to temporarily put the support bar in place and mark the bracket so you can drill a hole through the bracket and then you can use the supplied parts (basically making the parts fit). So, for me this was a 2 day job (4 hours each day) for a 69 year old man with a bad back, working by himself with 2 floor jacks,4 jacket stands, outdoors on a concrete driveway.




by:

This wet bushing kit was installed along with an SRE 4000 rubber suspension upgrade. The combination made the 36 ft. toy hauler ride and tow much smoother and the shackles were a much needed upgrade as the originals were very worn. This kit seems to be holding up very well.




by:

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.




by:

Everyone I worked with was very helpful although they could’ve when they emailed me the invoice had part numbers mor ride and their own part number so you know what you’re looking at




by:

The MORryde Suspension kit arrived in excellent condition and installation instructions were included. It took more time to jack up the trailer and put safety stands under than it did installing the shackles.




by:

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


Comments
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.

Definitely a smoother ride for the trailer, less bucking and noise. After two bent spindles, the MORyde system made our lives on the road for 10’s of thousands of miles much safer and extended tire the mileage.




by:

Arrived in a timely manner. I am very impressed with the extra heavy duty shackle links




by:

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!




by:

Very easy installation. Excellent product. Hardest part was securing the trailer safely.




by:

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




by:

Probly a good product some how would not fit pretty sure I went over this with sales person but my trailer is 30 in wheel base would not work found out after installed i have them for sale




by:

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.




by:

So far so good. Used trailer twice since install. Seems like the same towing feel. Just knowing I have a better suspension helps my overall traveling mind set.




by:

The morryde suspension kit is heavy duty and will probably outlast my trailer.
