It is tough to get a correct eye-to-eye measurement on a double-eye leaf spring when the spring is still installed in the suspension. It is much better to measure for a replacement leaf spring by removing it first. Also, if a spring is very old and well-worn it can actually become longer than it was when new. Years of use can cause a leaf spring to elongate by as much as 1/2 to 3/4-inch.

In a 1-3/4-inch wide double-eye spring rated for a 3500-lb axle, we offer the 4-leaf # SP-210275 which measures 27-inches from eye to eye as shown in the linked image.

The spring that you referenced, Redline # SP-218275, measures 25-1/4-inches from eye to eye, and is a 4-leaf 1-3/4-inch-wide spring rated for 5000-lb axles. This could be the original spring you have that has become longer from use and age. You'll know best by removing the spring before measuring it.

The linked page will show you all available 4-leaf springs in the 1-3/4-inch width. You can click on the filters on the page to narrow the results shown. I also included a link to our main page for all trailer suspension components, such as hangers, shackle straps, etc.

It is always best to replace the springs on both sides of the axle. This will ensure proper axle alignment and suspension performance.
