Question:

Hi. My question is about leaf springs. I measured my leaf spring on trailer. The measurement is 26 inches from bolt hole to bolt hole. The axles is rated for 3000 pounds. Going to put a 4000 pound axle underneath it now. Was wondering can I get heavier leaf springs the will fit?

If your eye diameter is 9/16 of an inch, then I recommend the Redline # e27SR leaf spring. I would double check the other measurements listed for this spring to ensure fit on your trailer, but this will work for your higher axle capacity and accommodate your 26 inch bolt hole to bolt hole spread. It's important to note that each spring carries 50 percent of the axle's weight rating.

I have linked an image with the measurements as well as a help article and installation video for your convenience.
