Replacement 3-Leaf Slipper Springs and Bushings for 1,200 lb Trailer
Updated 06/30/2025 | Published 06/20/2025
Question:
How do I know what kind of material wise leaf springs bushings or which type or material I need for what appears to be a 3 leaf spring perhaps referred to as slipper springs. I am assuming in this that these leaf springs require a bushing of some type for where the fastening bolt goes through on the front of each of these two springs. I believe the trailer it rated as 1200 lbs maximum capacity.

Hey Dave, thanks for reaching out!
It looks like our 24-5/8" Long 3-Leaf Slipper Spring # e99SR is going to be the best replacement for your setup.
This comes with a nylon bushing (which is standard) in that eyelet, so you actually won't need to get a whole new bushing either. I do recommend checking on the weight rating though. This spring is designed for axles up to 1,500 lbs and while your overall weight rating is near that range, we do want to make sure you aren't over or under loading your springs by much.
Let me know if you have something different, and I'll be more than happy to make a different recommendation if I need to!

Jon. I would also need to be sure what is included with these springs when ordered. I understand it would be best to replace both at the same time if they need replacement. Please list any separate parts required such as bolts. My hangers are welded on and have a single bolt I believe inf the front of each spring.

Jon, Can I assume you would need a current weight on the boat and equipment minus the weight of the trailer to be able to determine the over or under weight? I suspect since the MinnKota anchor winches were added from the original weight, there's a possibility of being over weight some vs. under weight. I doubt allot but I can try to get it double checked. For us the simplest means of achieving a weight is getting the boat with trailer weighed with the vehicle, subtracting vehicle and trailer weights to obtain the weight of the boat and equipment typically setting on the trailer. Does that seem correct? Thanks Dave
