Which Leaf Springs for my 5x10 Trailer with a 3,500 Pound Axle

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 PR626, or shorter springs, like a 25 1/4 PR4B? 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 # PR626, 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 25-1/4 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 your, part # PR4B, as you pointed out, would probably be the best to use. If your current springs are 3 leaves, then I would use part # PR3. 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 these parts in the warehouse, and they do have bushings already inside the spring eyes.
