ATI Performance Products ATI918044 Super Damper Harmonic Balancer Aluminum - 6.78 6-Groove

The ATI Performance Products ATI918044 Super Damper is a high-performance harmonic balancer specifically engineered for 2003-2004 Ford Mustang SVT Cobra models equipped with the supercharged 4.6L DOHC engine and OEM crankshaft support. This precision damper features a 6.78-inch diameter aluminum outer shell with six serpentine belt grooves, providing OEM-size fitment while delivering superior harmonic vibration control.

Key Features:

• 6.78-inch diameter aluminum construction for reduced rotating mass
• 6-groove serpentine pulley design for stock belt configuration
• Patented elastomer technology dampens harmful crankshaft harmonics
• Dual-damper design with inner and outer shells for maximum vibration control
• Engineered specifically for supercharged 4.6L Cobra applications
• Exceeds SFI 18.1 safety certification standards
• 360-degree laser-etched timing marks for precise tuning

ATI Super Dampers eliminate nearly all unstable crankshaft harmonic vibrations, allowing the engine to produce more horsepower and torque while maintaining long-term reliability. The proven elastomer is specifically designed and tuned to absorb parasitic vibrations that rob performance at high RPM. This damper requires a 1-thousandth inch press fit installation onto the crankshaft snout.
