Product Details

The COMP Cams XFi VVT hydraulic roller camshaft is specifically engineered for GM LS Gen IV engines equipped with Variable Valve Timing (VVT). This performance camshaft delivers a powerful combination of mid-range torque and top-end horsepower, making it an excellent choice for street/strip applications and aggressive street builds.

Camshaft Specifications:

  • Advertised Duration: 218° intake / 230° exhaust
  • Hydraulic roller lifter design for reduced friction and maintenance-free operation
  • VVT compatible - works with factory Variable Valve Timing system
  • Designed specifically for GM LS Gen IV engines (LS2, LS3, LS7, L76, L92, L99)
  • Aggressive lope at idle with strong acceleration characteristics

Key Features:

  • XFi (Xtreme Fuel Injection) profile optimized for fuel-injected applications
  • Maintains compatibility with factory VVT system for improved low-end response
  • Precision-ground lobes on high-quality core material for durability
  • Ideal power range: 1,800-6,400 RPM
  • Recommended for engines with aftermarket cylinder heads, intake, and exhaust systems

This camshaft requires compatible valve springs, pushrods, and a proper tune to maximize performance. It delivers excellent street manners while providing significant performance gains over stock. Professional installation and tuning are recommended to ensure proper valve train geometry and optimal engine performance.
