Key Features

  • Engine Application: GM LSA Series
  • Head Style: 12-Point
  • Material: 8740 Chromoly Steel
  • Finish: Black Oxide
  • Performance: High-Boost and High-Horsepower Ready

Precision is key when dealing with forced induction engines. These bolts are manufactured with exact tolerances to ensure uniform clamping force across the entire cylinder head surface. The 12-point design allows for precise torque application, minimizing the risk of bolt fatigue. By choosing this kit, you are investing in the long-term health of your engine, ensuring that your LSA stays sealed and performing at its peak. The black oxide finish adds a layer of protection against corrosion, making this kit suitable for both daily drivers and dedicated race machines.
