Spring Rate (F/R): 6.0 / 8.0 Height Adjustment (F/R): -3/8~-2in / -3/8~-2 3/8in SUSTEC PRO S-0C is for those who desire both high performance and maximum comfort from a suspension system. S-0C is ideal for performance or street applications. Dispelling a popular belief that a firm or harsh ride is a sign of a performance suspension, the short stroke, shortened case dampener of the S-0C is extremely unique in that it’s internal construction allows it to deliver superior handling without sacrificing strength or ride comfort. Unique double-cylinder design allows for full suspension stroke within the shortened shock body while Low-pressure gasses ensure smooth rebound characteristics for additional ride comfort.
