LT Cylinder Head Bolt Set | GEN 5 5.3L 6.2L 2014–2022 (LT1 LT2 LT4) V8| Thread Sealer – Torque-to-Yield | Replaces 19418279

This Gen V LT Cylinder Head Bolt Kit (Part #EQ-HB323N) is a complete replacement set designed for 2014–2022 5.3L and 6.2L LT engine platforms, including LT1, LT2, and LT4 configurations. Modern cylinder head bolts are torque-to-yield (TTY), meaning they stretch during installation and are not intended for reuse. Replacing head bolts during engine service is critical to maintaining proper sealing and consistent clamping force. This kit includes all required bolts for both cylinder heads and comes with pre-applied thread sealer to simplify installation. It is a reliable solution for engine rebuilds, cylinder head service, or general maintenance. Replaces OEM reference number: 19418279
