I don't have them in front of me to take a measurement....but the front springs are quite a bit shorter than the rears...I imagine it would be pretty obvious if that were the case!

I also imagine it would be pretty obvious by feel as well. rear Green springs are 2.00lbs, and front green springs are 3.15lbs. Should be able to feel the difference if that were indeed the case.

A spring difference is totally not out of the question though...
