ATP 102373 Engine Harmonic Balancer Crankshaft Damper

The ATP Graywerks 102373 is a high-quality OE replacement engine harmonic balancer, also known as a crankshaft damper or torsional vibration damper. Designed to restore proper engine operation, this unit is a direct-fit replacement engineered to match the form, fit, and function of the original equipment part.

How It Works:

A harmonic balancer mounts directly to the front of the crankshaft and is responsible for absorbing and dampening the torsional vibrations generated during engine operation. The assembly consists of a central hub that bolts to the crankshaft, a rubber or fluid dampening layer that absorbs vibration, and an outer metal ring with grooves that drive the serpentine or accessory belt. Over time, the rubber and fluid layer deteriorate, causing the outer pulley to shift and resulting in belt misalignment and potential crankshaft damage.

Key Features:

• Engineered to OE design specifications for a direct-fit replacement
• Manufactured with high-grade steel and precision machined to ensure zero runout
• Dynamically balanced and machined with counterweights for proper vibration absorption
• Rubber bonding process follows OEM-recommended procedures
• Woodruff key included where applicable to replace damaged or lost hardware
• Backed by ATP's Limited Lifetime Warranty

ATP Graywerks harmonic balancers are the trusted choice for restoring your engine's front-end accessory drive system to proper working order. Each unit is precision-built to ensure reliable, long-lasting performance under normal operating conditions.
