Product Details

The COMP Cams 156-400-13 XFI RPM series hydraulic roller camshaft is engineered specifically for GM LS Gen IV engines, delivering enhanced performance across the RPM range. This camshaft features a 210/224 duration split designed to optimize power delivery while maintaining excellent driveability characteristics.

Key Features:

  • Hydraulic roller design for reduced friction and improved longevity
  • 210° intake / 224° exhaust duration at .050" lift provides broad powerband
  • Hi-lift profile optimized for increased valve lift and improved breathing
  • XFI RPM series grind balances performance with street manners
  • Direct fit for GM LS Gen IV engine applications
  • Compatible with stock hydraulic roller lifters and valve springs (verification recommended)

This camshaft is ideal for street performance and mild street/strip applications where improved mid-range to upper RPM power is desired without sacrificing low-end torque. The hydraulic roller design maintains quiet operation and eliminates the need for valve lash adjustments. COMP Cams manufactures this camshaft from premium materials with precise lobe profiles to ensure consistent performance and durability.
