I just installed airbag suspension and now have a set of extra 4" lowering springs.

Specs on the springs:
Ordered from GMCPauls and installed August 2005
Truck sat October 2005-Present (snow in SD)
Removed March 2006
4" coil springs for 67-72 Chevy/GMC Pickup -- (Mine is a 70 GMC C1500)

Make me an offer. I live in SE South Dakota (57110) for shipping/pickup.
