Comparing Different Leaf Spring Sizes for 3500 Lb Trailer Axle

Question:

I am trying to replace the springs and hangers on a 3500 pound axle. I would like more info on the difference between the 27 inch and 25 1/8 inch 4 leaf springs. I would also like to know the differences in the hanger sizes

The difference between the two spring lengths really just comes down to what the distance between the hangers is on the trailer. There isn't an advantage to a longer or shorter spring so it's best to just match the length with what the trailer calls for.

The more common size is definitely the 25-1/8 inch part # e54SR over the 27 inch long # SP-210275.
