Hi David! Great question, when it comes to finding the right shackle and bolt kit for your MORryde ALLTREK 4000 part # MR89DR, you’ll need to do a little bit of measuring first.
There are two main kits to choose from, and it all comes down to the length of your current shackle straps. You will need to measure from center to center on the bolt holes:
If your shackles measure 2-1/4", go with kit #MR46ZR
If they’re 3-1/8", you’ll want kit #MR76ZR
Please let me know if you need any help deciding on the kits by commenting below!
