ATI Performance Products ATI917317 Super Damper Harmonic Balancer Ford - 6.78 3.3L 3.5L 3.7L V6

The ATI Super Damper ATI917317 is a high-performance harmonic balancer engineered specifically for Ford 3.3L, 3.5L, and 3.7L V6 engines, including Mustang and Raptor Ecoboost applications. This damper provides superior protection against destructive torsional crankshaft vibrations across all RPM ranges, especially during high-performance and competition use.

Key Features:

• 6.78-inch diameter aluminum shell construction for lightweight strength
• Dual belt drive system with 6-groove and 4-groove configurations in outer shell
• 4% overdrive ratio from OEM for improved accessory performance
• Laser-etched timing marks for precise ignition timing
• 4140 heat-treated steel hub with single 3/16" keyway
• Exceeds SFI 18.1 certification for racing applications
• Direct replacement for OEM Ford part #HL3Z-6312-A

Unlike OEM dampers that are optimally tuned to a narrow band of normal driving conditions, the ATI Super Damper delivers balanced dampening across all engine speeds and driving conditions. The patented multi-ring elastomer design absorbs harmful vibrations that can damage crankshafts, bearings, and other critical engine components, making it ideal for modified engines, forced induction applications, and racing use.
