S&S CYCLE Cam - 450 Series - Big Twin 33-5063

If you're running a lower-compression Big Twin and need reliable torque delivery across the RPM range, the S&S 450 Series cam delivers proven performance without sacrificing streetability. This is a bolt-in upgrade backed by hundreds of dyno, street, and track test hours—not marketing claims. You get the engineering expertise of a manufacturer that's been refining Harley powerplants for decades.

Designed specifically for motors with compression ratios up to 8.5:1, this cam excels at generating low and mid-range torque where you'll actually feel the difference. Solid lifter compatibility means zero valve train slop and precise power delivery, while U.S.A. manufacturing ensures quality control at every step.
