Reliable Performance for Cylinder Head Installs
When installing a cylinder head, using new head bolts is always a smart choice—and for late-model engines with TTY (torque-to-yield) head bolts, it’s absolutely necessary. TTY bolts are designed to deliver maximum clamping force for a tight head gasket seal, but they permanently stretch during installation and can fail if reused. The Victor Reinz Head Bolt Set ensures a secure, reliable fit for optimal engine performance.
