ATP 102166 Engine Harmonic Balancer

The ATP 102166 engine harmonic balancer, also called a crankshaft damper or crankshaft pulley balancer, absorbs crankshaft vibrations. It is built to the original equipment design so it installs and works as intended.

Key Features:

• Dynamically balanced to absorb crankshaft vibration
• Precision machined to zero runout for smooth performance at all engine speeds
• 6S (six-groove serpentine) balancer design
• No keyway

A worn harmonic balancer can let the outer pulley drift out of alignment and put extra stress on the drive belt. This replacement balancer restores the damping function of the original part.
