The 3-Leaf Double-Eye Spring # D217242 that you referenced would work perfectly for you. You are correct, springs tend to flatten out over time so that is why your old spring is slightly longer than the # D217242.

We always recommend you replace leaf springs in pairs to ensure a balanced load on the trailer when towing.
