This set centers on reliable operation, precise oiling paths, and a clean installation experience, making it a solid choice for enthusiasts who rebuild or refresh their LS engines without active fuel management.

Engineered as a direct upgrade from the GM OEM 12499225 reference, these lifters are the Delphi/LS7 style you know from a factory fresh setup. The kit includes 16 lifters and 4 guide trays, packaged to support a balanced, predictable lifter seating process and help preserve consistent performance over time.

What’s Included

Why Dynosty

  • Direct OEM-style replacement designed for longevity and dependable lifter wear
  • Delphi-based design aims for smooth lifter action and consistent oiling paths
