Mopar Performance 06510763AA Crankshaft Damper Bolt with Washer for HEMI Engines

The Mopar Performance 06510763AA is a genuine OEM crankshaft damper bolt with coned washer assembly designed to secure the harmonic balancer (vibration damper) to the crankshaft on modern HEMI engines. This critical fastener features a 14mm thread pitch and is engineered for precise fit and reliable retention under both normal and high-performance operating conditions.

Key Features:

• Genuine Mopar OEM quality hex head bolt with integrated coned washer
• Torque-to-yield design ensures proper clamping force
• 14mm thread pitch for modern HEMI applications
• Single-use fastener - must be replaced if removed and cannot be reused
• Designed for proper fit and durability on factory and performance builds

This is a torque-to-yield fastener that permanently deforms during installation to achieve the correct clamping force. If you remove the crankshaft pulley or harmonic balancer for any reason, this bolt must be replaced with a new one to ensure safe and reliable engine operation. Using the correct OEM replacement ensures your damper remains securely attached under all operating conditions.
