Product Details

The COMP Cams K12-417-8 Xtreme Marine camshaft kit is a complete hydraulic roller cam package designed specifically for Chevrolet small block engines in marine applications. This performance camshaft features 218°/224° advertised duration and is engineered to deliver excellent mid-range torque and horsepower while maintaining smooth idle characteristics suitable for marine use.

Complete K-Kit Includes Everything You Need:

  • Hydraulic roller camshaft with optimized marine profile
  • Hydraulic roller lifters for reduced friction and improved durability
  • Performance valve springs engineered to match cam specifications
  • Steel retainers for reliable valve train operation
  • Valve locks (keepers) for secure retention
  • Valve stem seals to prevent oil consumption
  • Timing chain set for precise cam timing
  • Assembly lube for proper break-in procedures
  • COMP Cams decals and detailed installation instructions

This Xtreme Marine series camshaft is specifically designed to handle the demanding conditions of marine environments, including sustained high RPM operation and exposure to moisture. The hydraulic roller design reduces friction compared to flat tappet cams while providing excellent durability and requiring no valve lash adjustments. Ideal for marine small block Chevy applications seeking improved throttle response and power delivery throughout the RPM range.
