Buying advice

When choosing flywheel bolts, consider the engine's RPM range and power output. ARP bolts are widely recommended for their strength and consistency. Ensure proper thread engagement and torque to specification. For high-performance or racing, upgrade to ARP2000 or L19 material; for street use, 8740 chromoly is sufficient. Always use new bolts when replacing the flywheel.
