Can Boat Trailer Replace Slipper Springs With Double Eye Springs?  

There are no U-bolts to attach the slipper part, I recommend replacing your slipper springs with double eye springs. In order to do this you need to know the weight rating of your axle as well as the length from center eye to center eye so you can…

I definitely recommend replacing your 3,500 lb 26 inch leaf springs with the 26 inch 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles #e22YR. The 4,500 lb would be too stiff and your ride would suffer so the better option by far are the 4k…

Our general rule of thumb is that the hanger spacing should be 1/4" -1/2" less than the length of the leaf spring. There is a small amount of tolerance,(1/2" or less) but not much. I do not recommend using a…

Sorry for the confusion but with the mounting brackets for your single axle trailer being separated 25-3/4" on center you will need to use a 26" leaf spring. We offer this length leaf spring in a couple different weight capacities.…

I spoke with my contact at Fulton and as long as the part that swings away when using the Fulton Fold-Away Coupler Hinge Kit #FHDPB350101 is not very long (which is doesn't appear to be) you will be just fine. If it were fairly long then…

As a general rule of thumb on a single axle trailer the hanger spacing should be around 3/8" shorter than the spring eye to spring eye measurement of your leaf spring. So for a 23-1/8" long leaf spring like the #e59SR you would want your…

For the spring eye you would use the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long #166079, but slipper springs don't have the second spring eye, so a bolt is not used on the back end. You can also use a wet bolt like…

If you can get me the overall length of your slipper springs and the axle capacity of your trailer I can help you pick out the correct replacement.

You will want to remove your spring hangers and then weld them in a position that allows the shackles to hang properly. On a spring that is 26 inches eye to eye on center and a single axle trailer you will want the hangers to be up to 1/2 inch less…

The recommended distance between the hangers of the #APS1 would be 24-7/8 inches when using the leaf spring #e54SR. When the trailer is set on the ground and the leaf spring is supporting the weight of the trailer the spring will flatten out and get…

Good question, and what happens is that leaf springs elongate over time, and since you mentioned you got measurements of 25-1/2 inches from center eye to center eye and 26 inches under partial load, the best option for leaf springs really is the…

Thank you for providing the specs for the suspension components that you already have. Correct hanger spacing really depends on the components being used such as springs, hangers and equalizers. Most of the hanger spacing dimensions that we have are…
