Product Details

The COMP Cams K54-418-11 XFi RPM K-Kit is a complete hydraulic roller camshaft package designed specifically for GM LS Gen III and Gen IV engines. This comprehensive kit provides everything needed for a camshaft upgrade, delivering improved performance with 224/228 duration specs that enhance mid-range power and throttle response.

Complete K-Kit Includes:

  • XFi RPM hydraulic roller camshaft with 224°/228° advertised duration
  • High-performance hydraulic roller lifters engineered for LS engines
  • Beehive valve springs for reduced valve train weight and improved RPM capability
  • Chromoly steel retainers designed for beehive spring applications
  • Precision valve locks for secure valve train operation
  • Premium valve stem seals to prevent oil consumption
  • Double roller timing chain set for accurate valve timing
  • Assembly lube to ensure proper break-in and protection
  • COMP Cams decals and detailed installation instructions

This camshaft profile is ideal for street/strip applications, providing excellent power gains from idle to 6,200 RPM while maintaining good vacuum for power brakes. The hydraulic roller design offers the performance benefits of a performance cam with the durability and low maintenance of hydraulic lifters, making it perfect for engines with stock or mildly modified cylinder heads and intake systems.

Key Specifications: The 224/228 duration split provides strong torque characteristics while the hydraulic roller design eliminates the need for break-in procedures required with flat tappet camshafts. Compatible with stock LS engine components including factory fuel injection, emissions equipment, and computer controls.
