Product Details

The COMP Cams 54-468-11 is a specialized hydraulic roller camshaft engineered specifically for GM LS Gen III/IV engines equipped with Roots-style superchargers. This LSR (LS Roots) series camshaft features a 247/251 duration split designed to optimize power delivery and boost response in forced induction applications.

Key Features:

  • Hydraulic roller design for quiet operation and reduced maintenance
  • 247/251 advertised duration optimized for Roots blower compatibility
  • Engineered specifically for GM LS Gen III and Gen IV engines
  • Valve timing calibrated to maximize boost efficiency and prevent reversion
  • Milder duration profile reduces stress on valvetrain components under boost
  • Maintains strong mid-range torque while supporting upper RPM power

This camshaft is ideal for street/strip vehicles and performance builds running Roots-type superchargers like Eaton or Magnuson units. The hydraulic roller design provides excellent durability and compatibility with factory-style valve train components, making it a smart choice for forced induction LS swaps and upgraded OEM applications.
