Lightly used and in outstanding condition foes Curnutt air rear shock.  Made in California 11.25" eye to eye 3.25" stroke.   This came directly from foes when they recently moved locations so I don't know its history but it appears to be in outstanding condition. Rebound damping and preload adjustable. Dual air chambers.   I pumped 150psi into both chambers and a week later it's holding air
