Video Transcript for Review of MORryde Trailer Leaf Spring Suspension - Spring Mounting Hardware - MR78ZR

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the MORryde Shackle Upgrade Kit for your tandem axle trailers with the MORryde RE suspension and the 35-inch wheelbase. Now, this heavy duty shackle kit is an excellent upgrade for your RV suspension. This kit is designed for the tandem axle trailers that have the MORryde RE Leaf Spring Suspension, has the 2 1/4-inch shackles, and a 35-inch wheelbase. Now, what's nice on this upgrade kit: The shackle straps that they use are very large, 1/2-inch thick shackle strap, which is thicker and stronger, more durable than the standard 1/4-inch thick factory brackets. If you notice, they also use bronze bushings to increase durability over the standard plastic bushing and the bolts that are used, the shackle bolts, they use the greasable bolts, which are known as wet bolts.

They're easily maintained to help minimize wear and tear versus a dry bolt. Now, basically in a multiaxial system the shackles is what'll link the springs and your equalizers in the suspension system. The shackles will handle the most movement and weight in a suspension setup. Therefore they are the most likely component to wear and they should be checked frequently. The shackle bolts is what holds the shackle straps to your Leaf Springs and to your equalizer and normally uses dry bolts.

But as we've mentioned earlier these come with the wet bolts. The dry bolts basically over time can wear out and fail. The wet bolts, what you end up doing with those, as you notice, has the Zerk fitting, the grease Zerk fitting. You can attach a grease gun to it, pump grease to where it goes inside the bolt, and it will come out this little hole and with your bushing installed it'll go on the inside of the bushing and grease it. So it gives you lubrication, helps 'em wear a lot longer.

Now, this upgrade kit will replace the shackle straps, the bushings, the bolts, the locknuts on your RV suspension system. All these parts laid out here on the table are included. Basically, it comes with eight- one, two, three, four, five, six, seven, eight of the 2 1/4-inch long, 1/2-inch wide shackle straps. And on the shackle straps, when we say the length is 2 1/4 inches, basically that measurement is from the center of this hole to the center of that hole. Also comes with eight of the 9/16 diameter by 3 3/8-inch long wet bolts.

Comes with four of the 9/16 diameter by 2 7/8-inch long wet bolts. Eight of the bronze bushings. Comes with 12 of the 7/16 size flange locknuts. Comes with these two steel equalizers with the hardware for installation and a nice installation instructions that'll describe how these parts all go together. These parts are made in the USA. But that should do it for the review on the MORryde Shackle Upgrade Kit for the tandem axle trailers with the MORryde RE suspension and a 35-inch wheelbase..

Review from a similar Shackle Upgrade Kit in Trailer Leaf Spring Suspension


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!

The wet bolt shackle kit w/ correct track is a good heavy duty kit. However the description stats it will work on a standard set up. And it will, but you will need to buy 2 9/16'' x 3'' bolts to correctly install.

Review from a similar Shackle Upgrade Kit in Trailer Leaf Spring Suspension


So far so good, I hate doing reviews right after the install but I will update if things go south. Hint- the shackles do not press tight against the springs. Its obvious why when I thing about it because it needs room to travel. But while tightening the bolts there was a little slop until I figured out why...

During my upgrade to the CRE3000 and X-Factor cross member I upgraded the wet bolts too. My only issue was that I ordered the wrong kit. My trailer doesn't have the correct track so two of the wet bolts were too long. I called MorRyde and they are sending me the two wet bolts and then I will install.

Review from a similar Shackle Upgrade Kit in Trailer Leaf Spring Suspension


I purchased this upgraded product to eliminate the squealing and binding from my suspension that had worn thru the oem nylon bushings. I have used this kit on my previous trailer and was very satisfied with the upgrade and added safety that comes with the bronze bushings, hardened bolts and half inch thick shackle connections. I am very satisfied with this product and etrailer.

It was good to hear that they were shipping sooner than expected as we are going on vacation the first week of August. This gives me time to get them installed. They look like good quality parts. Thanks again for all that you did.

The Grade 5 or maybe 3 ?? greaseable bolts have really cheap flange nuts. They easily strip. Grade 8 hardware would be a much better choice for an HD Upgrade kit.

Bought this complete kit to replace one I installed back in 2015 and about 30000 miles ago! Cheaper than just bolts and bushings and all the small bolts are now fresh also. Prompt delivery. Hardware is plastic sealed to a card, no worries about something being lost during shipping due to a damaged box.
