This Cylinder Head Bolt Set is a complete replacement designed for 2014–2017 4.3L V6 engine applications. Cylinder head bolts are torque-to-yield (TTY), meaning they stretch during installation and are not intended for reuse. Replacing these bolts during engine service is essential to maintain proper clamping force, prevent leaks, and ensure long-term engine reliability. This set includes the necessary bolts for cylinder head installation and is load tested by EngineQuest to help ensure consistent strength and performance under demanding conditions. It is an ideal solution for engine rebuilds, cylinder head replacement, or routine maintenance. Designed as a direct replacement, this set matches the required fit and function for applicable engines. Replaces OE reference number: 11546959
