Please help us find a replacement leaf spring for a very heavy duty boat trailer?

We have a custom built trailer, built 40 years ago. Due to the very special design of the trailer, a near exact replacement is needed.

DESCRIPTION: 2 inch wide, 4 Leaf, Flat end Slipper type, 29 1/2 inches from pivot center to end, 3/4 inch pivot ID, and the leaves are roughly 7/16 inch thick, or 400 thousandths as measured with micrometer. We do not know the load rating of this spring.

We do know the spring was salvaged from a very large mobile home's axle assembly.

Could you please help us find a source for replacements? The most important specifications are the width (2") and the pivot hole. (3/4") Possibly a different number of leaves could work also. Any and all suggestions will be appreciated very much.

Thank you for your help.

    You should be able to find a "Spring" shop in your town. What they will need is either the spring itself, or all of the specs and weight capacity of the trailer, or all of the above. They will then custom make a new set of springs for you. It's best to replace both as a set rather than just replace a single spring.

    Trying to find a new spring for a 40 year old trailer just isn't going to happen without any knowledge of where it came from or what it's off of.
