Hey Jeremy. I have all of the parts you'll need but I am going to need you to take a couple of measurements. There's no database that shows me what parts you have on your toy hauler. To replace your springs, I'll need you to jack up one side of the trailer(or both) and get the bolt hole to bolt measurement off of one of your leaf springs. They tend to stretch out over years of use and this is the only accurate way, other than a part number, to find out what size you need. I'll also need to know how many leafs are in your springs.
For replacement MORryde equalizers and hardware, I have two options for both and they are listed below. To determine which equalizer kit you'll need you'll want to look at the attached diagrams and compare those measurements to your current equalizers and pick the closest one. The shackle straps and wet bolt kits will be the same way. You'll want to measure from the center of one bolt hole to the center of the other on a shackle strap and pick the kit closest.
MORryde Shock Absorbing Suspension Equalizers for Triple Axle Trailers w/ 33" Wheelbase - 8K item # MR59ZR
MORryde Rubber Equalizers for Triple Axle Trailers - 35" Wheelbase - 8K item # MR39ZR
MORryde Suspension Upgrade Kit for Triple Axle Trailers - 2-1/4" Long Shackle Straps item # MR86ZR
MORryde Suspension Upgrade Kit for Triple Axle Trailers - 3-1/8" Long Shackle Straps item # MR26ZR
If your current equalizers and shackle straps are way off dimensional wise please let me know so we can look at alternative options than a MORryde setup.
You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.
