S&S Cycle 330-0093 508 Series Bolt-In Camshaft for Evolution Big Twin Engines

The S&S Cycle 508 Series Camshaft (330-0093) is a bolt-in performance cam engineered for Evolution Big Twin engines running less than 10:1 compression. Designed to deliver a noticeable improvement in low- and mid-range torque without sacrificing street manners, the 508 is an ideal upgrade for touring riders and two-up applications where smooth, tractable power matters most.

Every S&S camshaft goes through extensive dyno testing on the street and track before release, ensuring real-world performance you can count on. The 508 grind is known for its exceptionally quiet valvetrain characteristics, making it one of the most streetable performance cams in the S&S lineup. This cam is sold individually and does not require high-lift valve springs, making it a true bolt-in upgrade for stock engines.
