  • Valve Lift: .550" Intake / .550" Exhaust (with 1.7:1 rocker ratio)
  • LSA (Lobe Separation Angle): 116°
  • Designed for use with stock or aftermarket valve springs

Features & Benefits:

  • Low Spring Tension design reduces valvetrain stress and wear
  • Optimized grind specifically for manual transmission applications
