Converting Shorelandr Boat Trailer from Slipper Spring to Double Eye

Question

Question:

Good morning, I have a shorelandr trailer with springs OEM #4610048. Im looking for a aftermarket replacement because shorelandr doesnt have them. The eye-to-eye is 25-1/4, 3000lb capacity, 1-3/4 wide, and is a C-spring. Do you have something? Or can I convert to double eye?

The best solution is going to be to go with a double eye leaf spring setup instead of what you have now. For that the leaf spring part # e57SR is for a 4,000 lb axle and has a 25-1/4 inch length from eye to eye. Then for a hanger kit you'd want the part # APS4 and you'd be set. There isn't a slipper spring setup that matches what you are looking for.

What about for the double axle shorland'r trailer? Is there an aftermarket setup to convert to double eye? My OEM part number is the same as above for replacement springs.

@Dino What I mentioned above would also work.

Answer 1

The two tire sizes you referenced, 4.80-12 and 5.30-12, both fit 4-inch wide rims, but they differ in their overall diameter. A 4.80-12 tire/wheel when fully inflated will have a diameter of 20-1/2-inches while the 5.30-12 size will be just under…

Hey Neil. The #AM30861 and #AM35354 are very similar in size. The Kenda Karrier ST145/R12 Radial Trailer Tire #AM35354 is actually slightly smaller in diameter than the Kenda 5.30-12 tires, so out of the two 12" tires you mentioned, this will be…

Thanks for the picture! I have something close to your 26" slipper springs. It is possible to switch to a two eye leaf spring or even go down to a four leaf spring with a higher capacity. If you wanted to switch it up to a two eye leaf spring I…

I gave Shoreland'r a call and according to the information listed for your VIN, your trailer is equipped with a 1-1/16" spindle. For this you can use Replacement Trailer Hub Bearing, #L44649. Although Shoreland'r was able to provide this…

Answer 7

Since you said it was a hook leaf spring it sounds like you have a slipper spring on your trailer that you are looking to replace. Depending on your axle rating we have a few options. For a 1,000 lb axle part #WIC2, for a 2,000 lb axle part…

Answer 8

A bushing isn't required for slipper springs, but if your bolt has one it would reside in the "C" pocket at the end of the spring. The one thing that would worry me is that extra drilled hole on that hanger being too close to the…

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…

Answer 10

If the trailer currently uses double-eye spring suspension then you will want to use slipper spring hangers if you want to switch spring types. Double-eye hangers would not work in the manner you have described because the shackle bolts are not large…

Answer 11

Hey Dirk, in general double eye is a smoother ride quality than a slipper since there's more friction with a slipper setup but if the boat trailer will see saltwater I would go with slipper since there would be fewer components that would rust…

Answer 12

Hello Jack, thanks for reaching out. So I am not seeing we have a spring in that exact length. The closest we have would be a 20-7/16" Long 3-Leaf Double-Eye Spring #DX93CR which is for a 1,400 lb light duty axle. What is the weight capacity of…
