  • Duration at .050": 219°/235° intake/exhaust
  • Valve Lift: .525"/.525" with 1.7:1 rocker ratio
  • Lobe Separation Angle: 115°
  • Hydraulic roller design for quiet operation and minimal maintenance
  • LSR (Low Seat Ramp) profile for improved valvetrain stability
  • Compatible with stock valvetrain components

Application Notes:

  • Designed for GM Gen IV engines (LS2, LS3, L76, L92, L99) without VVT or AFM
  • Not compatible with engines equipped with Variable Valve Timing or Active Fuel Management
  • Requires valve spring upgrade for optimal performance
  • Idle characteristics: Smooth to mild lope
  • Recommended RPM range: 1,500-6,000 RPM
