Question:

My 6-year old double-eye leaf springs for my 5x10 single 3500 lb. axle trailer measure exactly 26 from eye to eye. The front eye mounts directly to a hanger, while the rear eye is connected to the hanger with shackle links. In another answer posted on your website, you stated that leaf springs stretch over time with use. Should I purchase 26 replacement leaf springs e27SR, or shorter springs, like a 25 1/4? Also, do either of these leaf springs come with bushings, or do I need to purchase the bushings separately?

There is a lot of variance in how much a spring will stretch. A trailer that carries a lighter load or is not used frequently will not have as much spring stretch. The springs you were looking at, part # e27SR, are made for trailers with 4,500 pound axles. It might result in a bit rougher of a ride.

The double eye springs we carry for a 3,500 pound axle are 25-1/8 inch long. At six years of age, I can see the springs stretching 3/4 of an inch. We have two springs that would work for you, part # e54SR, would probably be the best to use. Always try to match your new springs as closely as possible to the original springs so that the trailer will have the same suspension behavior that you are used to.

I double-checked this part in the warehouse, and they do have bushings already inside the spring eyes.
