Product Details

The COMP Cams 189-303-13 Stage 2 LST (Late Model LS Truck) camshaft is specifically engineered for L99 engines equipped with automatic transmissions and Variable Valve Timing (VVT). This performance camshaft delivers a significant upgrade over stock, providing improved throttle response, increased horsepower and torque throughout the powerband, while maintaining excellent street manners and drivability.

Key Features:

  • Designed specifically for L99 engines with automatic transmission and VVT systems
  • Stage 2 performance profile delivers noticeable power gains without sacrificing reliability
  • Maintains compatibility with factory VVT components for optimal performance across the RPM range
  • Improved airflow characteristics for better cylinder filling and combustion efficiency
  • Engineered to work with stock valve springs and related components in most applications
  • Aggressive idle tone with excellent street drivability

This camshaft is ideal for L99-equipped Camaros seeking a balanced performance upgrade that enhances power delivery while retaining the benefits of variable valve timing technology. The Stage 2 profile provides an excellent foundation for naturally aspirated performance builds focused on street and occasional track use.
