My 4x4 has blue springs and looks like its been lowered slightly. Are blue springs synonymous with any specific company? I would have thought standard Ford ones were black as oposed to blue?

I want to know if they are standard springs or aftermarket ones. Cheers.

 

They most likely will have the spring rate stamped on them, or if not test them easy to do yourself with bathroom scales.
