I bought a match set of axles all set up for a spring over and the perches are set up for a 2.5" wide spring. Not an issue for the front - found Skyjacker GM spring that work, but are too long for the rear.

Has anyone swapped out to a wider spring? If yes, what spring did you use - part number would be great.

I have talked to a few "Binder" shops but all they can offer is a bolt on 2" spring. I would like to upgrade to the wider spring and not have to cut the perch and replace with 2".
