I realize your post above is meant to be funny^^^^ but I'd say "barnco's" post is a serious one, and there are not a lot of threads on spring failure.

When I bought my 2005 Z51 that I converted into a racecar, I found that the original spring had split exactly as you have described. I replaced it with a C5Z06 spring and it's been fine ever since.

There have been reports of spring failure caused by chemicals attacking the spring. Aluminum brighter (used on suspension parts) is one culprit, there are probably others but I don't know them.

Impacts with big rocks, or accidentally jacking on the spring, are also possibilities.
