  • Cam is easy starting, increases throttle response and fuel mileage. Responds well to increased compression ratio, performance exhaust and a high-flow air cleaner
  • 1900 - 6000 rpm power range
  • The 'Freeway Flyer', great camshafts for those who want more top end power than the 525 cams without sacrificing low end torque
  • Extremely smooth cam lobe layout maintains quiet valve train and produces the smoothest cruise power band available
