Product Details

The COMP Cams 54-501-11 XFI solid roller camshaft is engineered for high-performance GM LS Gen III and Gen IV engines. This aggressive cam profile delivers 243° intake duration and 248° exhaust duration, providing excellent mid-range to top-end power for street/strip applications and aggressive street machines.

Key Features:

  • Solid roller design for maximum valve control and high-RPM stability
  • 243° intake / 248° exhaust duration for aggressive power delivery
  • Optimized for GM LS Gen III and Gen IV small block engines
  • XFI series profile designed for enhanced throttle response and power
  • Precision-ground cam lobes for consistent performance and durability
  • Requires matching solid roller lifters, valve springs, and supporting components

This camshaft is ideal for modified LS engines with increased compression, ported heads, and upgraded intake/exhaust systems. The solid roller design eliminates lash variation for precise valve timing throughout the RPM range. Professional installation and proper valvetrain setup are required to achieve optimal performance and reliability.
