Product Details

The COMP Cams CL12-417-8 Xtreme Marine camshaft and lifter kit is specifically engineered for marine applications in Chevrolet small block engines. This complete kit features a hydraulic roller camshaft with 218/224 duration specs, designed to deliver improved throttle response and reliable performance in wet marine environments.

Key Features:

  • Hydraulic roller design for reduced friction and increased durability
  • 218/224 duration profile optimized for marine torque characteristics
  • Corrosion-resistant components designed for marine engine environments
  • Complete kit includes camshaft, hydraulic roller lifters, assembly lube, installation instructions, and COMP Cams decals
  • Direct fit for Chevrolet small block engines
  • Engineered to work with stock valve springs and components in most applications

This Xtreme Marine series camshaft is ideal for boat owners seeking improved low-end and mid-range power delivery while maintaining smooth idle characteristics. The hydraulic roller design reduces valve train wear and provides quieter operation compared to flat tappet designs, making it well-suited for the demanding marine environment.
