I just took this off my SC Heckler after I upgraded to a RP23 for better climbing performance. It measures 8.5" eye-to-eye and has a 2.5" stroke, which fits several all-mountain bikes similar to the Heckler. The shock is less than a year old (I bought it new last fall) and is in perfect condition- see picture below. $100 plus shipping if necessary, located in Boulder.

Rebound Tune: M
Velocity Tune: L
Boost Valve Tune: 250

PM if interested.
