ATI Performance Products ATI918913S Super Damper Harmonic Balancer

The ATI Performance Products ATI918913S is a high-performance Super Damper harmonic balancer engineered to protect your engine from torsional vibration damage. ATI's Super Dampers are the industry standard in professional racing and high-performance street applications, offering superior vibration dampening compared to OEM-style rubber bonded units.

ATI Super Dampers use a precision-machined steel hub with a tuned elastomer ring and inertia ring assembly, effectively absorbing and dissipating harmful crankshaft torsional vibrations across a broad RPM range. This design dramatically extends the life of your engine's crankshaft, bearings, and accessory drive components under high-performance conditions.

Key Features:

• Precision-machined billet steel construction for long-lasting durability
• Tuned elastomer dampening ring for broad RPM vibration control
• SFI 18.1 certified for use in sanctioned racing events
• Replaces OEM harmonic balancer with a performance-grade alternative
• Designed for use with standard ATI timing pointer and degree markings
• Compatible with ATI and other leading aftermarket pulley and belt drive systems
