Product Details

The COMP Cams CK54-330-11 is a complete Stage 1 LST (Turbo) camshaft kit engineered specifically for GM LS 4.8L and 5.3L turbocharged engine applications. This kit is purpose-built to complement forced induction setups, featuring a cam profile optimized for turbo powerplants where a tighter LSA (lobe separation angle) and specific intake/exhaust timing events work in harmony with boost pressure to maximize torque and power output across the RPM range.

Camshaft Specifications:

  • Duration @ 0.050": 227°/241° (Intake/Exhaust)
  • Lift: 0.559" / 0.565" (Intake/Exhaust) with 1.7:1 rocker ratio
  • Lobe Separation Angle (LSA): 114°
  • Cam Type: Hydraulic Roller
  • Application: GM LS 4.8L / 5.3L Turbo engines

Kit Contents:

  • COMP Cams hydraulic roller camshaft
  • Matched hydraulic roller lifters
  • Timing chain set
  • Camshaft installation hardware

Key Features:

  • Turbo-Optimized Profile: Cam timing events specifically designed to build and maintain boost pressure efficiently in forced induction applications
  • Hydraulic Roller Design: Reduced valvetrain friction, improved reliability, and no lash adjustment required for street-friendly drivability
  • Complete Kit: All critical valvetrain components included for a straightforward installation without the need to source individual components separately
  • LS Platform Compatibility: Engineered to work within the LS engine architecture for Gen III/IV 4.8L and 5.3L displacements
  • Stage 1 Performance: Ideal entry-level performance upgrade delivering measurable gains in turbo throttle response and mid-range torque while retaining streetable idle quality

The COMP Cams CK54-330-11 is the ideal foundation for a turbocharged LS 4.8 or 5.3 build seeking real-world street and strip performance gains. As a complete kit, it simplifies the cam upgrade process and ensures all components are properly matched for reliability and longevity.
