Product Details

The COMP Cams 7228CS-KIT is a complete valve spring upgrade kit designed specifically for GM LS engine applications. This high-performance kit features conical valve springs engineered to provide superior valve control and resistance to spring surge at higher RPM ranges.

Key Features:

  • Conical valve spring design for improved stability and reduced harmonics
  • Chromemoly steel retainers for exceptional strength and durability
  • Complete kit includes springs, retainers, and locks for a full valve train upgrade
  • Engineered for GM LS engine platforms including LS1, LS2, LS3, LS6, and LS7
  • Enhanced valve control for performance camshaft applications
  • Reduced valve float at high RPM for improved power and reliability

This valve spring kit is ideal for street performance and racing applications where increased spring pressure and improved valve control are essential. The conical spring design provides progressive rate characteristics while the chromemoly retainers offer weight savings compared to stock components. Perfect for builds running aggressive camshaft profiles or higher RPM operating ranges.
