Ultimate Reliability for Your LS1 Drivetrain

When building a high-performance Chevy LS1 engine, the connection between your crankshaft and flywheel is a critical failure point. The ARP Chevy LS1 M11 Flywheel Bolt Kit is engineered to provide superior clamping force that exceeds OEM standards, ensuring your flywheel stays securely mounted under extreme RPM and torque loads.

Technical Specifications and Benefits

  • Material: Premium 8740 chromoly steel for high tensile strength.
  • Design: M11 thread pitch specifically engineered for LS1 crankshafts.
  • Quantity: Complete 6-piece kit for a full installation.
  • Finish: Black oxide coating for enhanced corrosion resistance.
  • Performance: Prevents bolt stretch and shear failure during high-performance driving.

These bolts are cold-forged and heat-treated to ensure they handle the stresses of racing applications, track days, or high-horsepower street builds. Unlike standard factory hardware, ARP bolts are reusable and maintain their torque specs consistently over time. Whether you are performing a clutch swap or a full engine rebuild, do not compromise on the hardware that keeps your drivetrain together. Trust the industry standard in fastener technology for your next project. Find all your essential engine hardware at GGCRACING.
