ATI Performance Products 918437 Super Damper Harmonic Balancer Overdrive HEMI - 17% 6.1L

The ATI Performance Products 918437 Super Damper is a high-performance harmonic balancer engineered specifically for 2005-2010 6.1L HEMI engines found in Dodge, Chrysler, and Jeep SRT8 vehicles. This patented crankshaft damper features a 17% overdrive design with a 7.48-inch diameter and 6-rib serpentine belt configuration, making it ideal for supercharged and high-RPM applications.

Key Features:

• 17% overdrive design increases supercharger speed without requiring smaller pulleys that can cause belt slip
• SFI 18.1 certified for both street and racing applications
• Aluminum 3-ring design outer shell with steel crankshaft hub for optimal strength-to-weight ratio
• 360-degree laser-etched timing marks for precise engine tuning
• Internal balance configuration eliminates harmful torsional crankshaft vibrations at all RPM ranges
• Rebuildable and tunable design with computer-machined grooves and application-specific O-rings
• Black zinc chromate finish for corrosion resistance

The ATI Super Damper uses a steel inertia weight suspended between inner and outer shells with precision-durometer O-rings that are dyno-tested for each specific application. This advanced elastomer construction provides balanced dampening of crankshaft vibrations, improving reliability and performance in demanding street and track environments. The 7.074-inch outside diameter and internally balanced design ensure direct compatibility with 6.1L HEMI engines and 392 HEMI crate motors.
