Product Details

The COMP Cams SK12-418-8 Xtreme Marine camshaft kit delivers proven performance for Chevrolet small block engines operating in marine and other moisture-prone environments. This complete SK-Kit (Small Kit) provides everything needed for a professional camshaft upgrade with a 224/230 duration hydraulic roller cam profile designed for reliable mid-range power and torque.

Complete Kit Includes:

  • Xtreme Marine hydraulic roller camshaft with 224/230 duration profile
  • Matched hydraulic roller lifters engineered for the camshaft specifications
  • Precision timing chain set for accurate valve timing
  • Assembly lube for proper break-in protection
  • Installation instructions and COMP Cams decals

The Xtreme Marine series features enhanced corrosion resistance and durability for harsh marine environments where moisture and saltwater exposure are concerns. The 224/230 duration profile provides improved throttle response and power delivery over stock camshafts while maintaining good idle quality and vacuum for street-friendly drivability. This hydraulic roller design reduces friction and wear compared to flat tappet camshafts while eliminating the need for break-in procedures required by flat tappet cams.

Key Features:

  • Marine-grade corrosion resistant coating and materials
  • Hydraulic roller design for reduced friction and maintenance-free operation
  • 224/230 duration for strong mid-range power and torque
  • Complete kit eliminates guesswork in component matching
  • Includes all essential installation components

This camshaft kit is specifically engineered for Chevrolet small block V8 engines and provides a reliable performance upgrade for marine applications, as well as street rods, muscle cars, and other vehicles where enhanced durability is desired.
