I just picked up a Mongoose ST 10.7 titanium with a Stratos XC Pro shock and I was wondering if someone could tell me what PSI range the shock is rated for. It has 1.5" travel.

Does anyone know if any other company ever made a similar 1.5" shock with the bolt hookup at the bottom? I found out that the Stratos was killed off by Specialized and if I ever need to replace the shock it would be nice to have an alternative option.
