We can help you with replacement leaf springs for your tandem axle boat trailer. We recommend to replace the springs on both sides of the trailer axle, not just the one broken one, to avoid problems with the trailer tracking straight as you go down the road.

If you click on the linked page you'll see our main page for trailer springs. Just click on the type you need, double-eye or slipper, and then on the axle weight rating. Usually there will be a sticker on your axle that tells you its weight capacity.

Then you'll just want to measure your spring (after you remove it from the trailer's suspension) to determine its length. Then click on that dimension to see springs that will work. The linked articles will help you determine the type of spring you have.

Do note that very old and well-worn springs can become a little bit longer over time. It is possible that a leaf spring can become as much as 3/4-inch longer than new due to flattening of the spring stack. If you do not see a spring length that matches yours exactly, then just keep in mind that when new your existing springs may have been a bit shorter than they are now.
