Its difficult to say what the issue is with your installation of trailer leaf springs with Redline U-Bolt Plate # 115983. If old and new parts are mixed there can be fit issues since old, worn parts may not have the same exact dimensions as they did when new. Leaf springs do stretch and elongate after years in service. A worn spring that measures, for example, 27-inches long from eye to eye may not have been a 27-inch spring when installed initially.

I suggest you submit a photo and more detailed information about the trailer's suspension. You can also refer to the linked articles on trailer suspensions for additional guidance.

Answer 8

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Answer 9

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind and…

Hey Patrick, so for your leaf spring upgrade I am going to need to know a couple of things before I can get you over to the right part. Specifically, the length from eye to eye, the spring width, leaf thickness, and the number of leaves. From here I…

Answer 11

Answer 12

The hangers you currently have on your trailer are ones I have run into before. That being said, I spoke with MORryde and the #MR27ZR will still fit your trailer, but there is a modification that will need to be made. You’ll have to trim according to…
