  • Greatly eases starting by first reducing compression; once the engine fires and rpm rises, the decompression cam retracts under centrifugal force, restoring full compression for normal operation with no loss of performance.
  • Designed in a bolt-in configuration for 103" engines with a stock compression ratio between 9.7:1 and 10.5:1, with no major internal modifications.
  • Delivers power across the entire rpm range, with a performance sweet spot between 2,500 and 5,500 rpm.
  • Complete kit includes camshafts, cover gasket, bearings, retaining ring, O-ring, threadlocker, and installation instructions.
  • Made in the USA for consistent quality and reliability.
  • Compatible with unported stock heads, while also ideal with S&S CNC-ported heads for maximum output.
  • Installer must verify: available spring travel/lift, valve-to-valve clearance, and valve-to-piston clearance.
  • Not compatible with models equipped with OEM compression releases.
