ATP 102165 Engine Harmonic Balancer

The ATP 102165 is an OE replacement engine harmonic balancer designed to restore proper engine operation by absorbing crankshaft vibrations. This critical component mounts directly to the crankshaft and features a three-piece construction with a hub that bolts to the crankshaft, a dampening rubber or fluid layer, and a grooved outer metal pulley ring for belt operation.

Key Features:

• OE replacement design for direct fit installation
• Three-piece construction for effective vibration dampening
• 5-groove serpentine belt configuration
• 6.53-inch outer diameter
• Part of ATP's Graywerks line of engine components
• Meets original equipment specifications

Harmonic balancers are essential for preventing belt misalignment and potential crankshaft failure caused by deteriorated dampening layers. When your harmonic balancer shows signs of wear, such as belt wobble or forward pulley shift, replacement is necessary to maintain engine integrity and performance.
