Product Details

The COMP Cams XFI VVT hydraulic roller camshaft is engineered specifically for GM LS Gen IV engines equipped with Variable Valve Timing (VVT). This performance camshaft delivers a 226/236 duration split designed to optimize power delivery while maintaining compatibility with factory VVT systems.

Key Features:

  • Hydraulic roller design for reduced friction and maintenance-free operation
  • 226/236 degree duration profile optimized for mid-range torque and top-end power
  • VVT compatible design works with factory cam phasers
  • Precision ground lobes for consistent valve lift and timing
  • Designed for GM LS Gen IV engines with VVT (L76, L92, L94, L99, LS3, LSA, LS9)
  • Direct drop-in replacement for stock camshaft

This camshaft is ideal for enthusiasts seeking improved performance from their Gen IV LS engine while retaining the benefits of variable valve timing. The hydraulic roller design eliminates the need for valve adjustments while providing excellent durability. Compatible with factory valve springs in most applications, though upgraded springs are recommended for maximum performance and reliability.
