• Patented design uses 70-durometer O-rings and a fully captured steel inertia ring instead of press-fit elastomer material
• Provides superior vibration dampening across the entire RPM range
• Tunable and rebuildable for long-term performance and value
• Steel construction with black zinc chromate finish for durability
• Laser-engraved 360-degree timing marks for precise engine tuning

Key Specifications:

• Outer diameter: 7.480 inches
• Internal balance design
• 8-rib serpentine belt configuration
• Features 18% accessory overdrive
• Exceeds SFI 18.1 safety specifications for racing applications

Unlike OEM dampers that can deteriorate over time and cause timing mark inaccuracy, the ATI Super Damper maintains concentricity and balance throughout its service life. The computer-machined grooves retain application-specific O-rings that have been dyno-tested to provide optimal dampening characteristics. Whether you're building a street performance engine or a dedicated race motor, this harmonic balancer delivers the protection and reliability demanded by serious enthusiasts and professional engine builders.
