Product Details

The COMP Cams 26925CS-KIT is a complete dual valve spring kit engineered specifically for GM LS engines. This performance upgrade kit features high-quality dual valve springs paired with chromemoly steel retainers to deliver reliable valvetrain control at higher RPMs and aggressive camshaft profiles.

Key Features:

  • Dual valve spring design for superior valvetrain stability and control
  • Maximum valve lift capacity of .660 inches
  • Chromemoly steel retainers for exceptional strength and durability
  • Direct fit for GM LS engine platforms
  • Complete kit includes springs and retainers for simplified installation
  • Designed to handle increased spring pressures from performance camshafts

This valve spring kit is ideal for LS engine builders looking to upgrade their valvetrain to accommodate performance camshafts with lift up to .660". The dual spring configuration provides the necessary seat and open pressures to prevent valve float at high RPM while the chromemoly retainers offer superior strength compared to standard steel retainers. Perfect for street performance, bracket racing, and high-performance street applications.
