Secure your crankshaft damper the right way with the Genuine GM Harmonic Balancer Bolt (Part #11547372), designed specifically for 2014+ Gen V LT engines equipped with a wet sump oiling system. This OEM torque-to-yield (TTY) bolt is critical for maintaining proper clamping force on the harmonic balancer, ensuring long-term reliability and preventing potential crankshaft or damper issues. Commonly referred to as a crankshaft pulley bolt, balancer bolt, or vibration damper bolt, this fastener is engineered to GM’s exact specifications for precise fitment and performance. Because it is a one-time-use TTY bolt, it must be replaced anytime the harmonic balancer is removed to ensure proper torque retention and engine safety.
