Question:

I would like to purchase these springs as replacements for my trailer. I understand the spring capacity is 2,500lbs. What is the spring rate?

So trailer leaf springs like the part # e28SR typically only flex about 1-1/2 inch when at capacity. So that means it takes 2,500 lbs for this spring to move 1-1/2 inches and spring rate is weight required to move spring 1 inch. That means it takes 1,675 lbs to move the spring 1 inch.
