  • Makes starting easier by first lowering compression; once the engine fires and rpm increases, the decompression cam retracts under centrifugal force, and the engine returns to full compression with no loss of performance
  • Designed as bolt‑in camshafts for 103” engines with a stock compression ratio between 9.7:1 and 10.5:1
  • Delivers more power across the entire rpm range, with optimal performance from 2,500 to 5,500 rpm
  • Complete kit includes camshafts, cam cover gasket, bearings, retaining ring, O‑ring, threadlocker, and installation instructions
  • Made in the USA
  • Compatible with stock, unmodified heads, while also ideal for S&S CNC‑machined heads
