Question:
I have a utility trailer with a single axle that I believe is 3500 lb. rating. It has double eye leaf springs that are 1-3/4 wide. I would like to buy an upgrade kit with wet bolts. I think the K71-358-00 kit is what I need. The only thing that doesnt match up with what I have is that the original shackle straps have holes at 2-9/16 between centers and the kit has 3-1/8. Will this work for my application or is there a better match?

Hey Phillip,
The Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00 would work but it's going to add a bit of extra height to your trailer and could potentially cause a bind up. Personally, I'd go with the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 2-1/4" Long Shackle Straps # MR46ZR instead to minimize the difference between what you have and what you're changing to so that the suspension can travel properly.
