Product Details

The COMP Cams K12-556-4 Nitrous HP K-Kit is a complete camshaft upgrade package designed specifically for small block Chevrolet engines running nitrous oxide systems. This hydraulic flat tappet camshaft features 218/230 degrees of advertised duration, delivering a broad powerband with excellent mid-range and top-end performance ideal for nitrous-assisted applications.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with nitrous-optimized profile
  • Hydraulic lifters matched to cam specifications
  • High-performance valve springs designed for increased valve control
  • Precision valve spring retainers
  • Hardened valve locks for secure retention
  • Valve stem seals to prevent oil consumption
  • Timing chain set for accurate cam timing
  • Assembly lube to ensure proper break-in
  • Installation instructions and COMP Cams decals

This all-in-one kit provides everything needed for a professional camshaft installation, eliminating the guesswork of component matching. The Nitrous HP grind is engineered to work with nitrous oxide's instant power delivery, featuring valve timing that accommodates the increased cylinder pressure while maintaining good vacuum and drivability. Ideal for street/strip applications where nitrous is used for supplemental power.
