VCM Camshaft + PSI Performance Spring set Package Deal

Lightweight Control • Proven Reliability • Street/Strip Ready

A balanced, cost-effective upgrade package designed for LS enthusiasts wanting a sharp bump in power while maintaining drivability and reliability. This bundle combines your choice of VCM Performance camshaft with PSI 1511ML beehive valve springs — one of the most popular spring choices on the market.

With excellent spring pressure, reduced valvetrain weight, and high-RPM stability for most street and moderate performance builds, the PSI springs are a trusted match for many VCM cam profiles.

What’s Included

• VCM Performance Camshaft (choose your grind)
  Engineered for precision power delivery and clean tuning.
• PSI 1511ML Beehive Springs
  Lightweight design improves valve control and reduces stress on LS valvetrain components.

DISCLAIMER: PSI single valve spring kits do not come with new retainers and collets – the factory retainers and collets are to be reused with your new valve springs.
