• Steel inertia weight with eight computer-machined grooves retaining precision-fit durometer O-rings for consistent harmonic control
• Aluminum or steel inner and outer shells for durability under extreme race conditions
• Black zinc chromate finish for corrosion resistance and clean appearance
• Computer-controlled, laser-engraved 360-degree timing marks for precise ignition timing
• SFI 18.1 certified — exceeds SFI specifications, tested in NASCAR Winston Cup competition over two million cycles and in drag racing engines for over ten years
• Compatible with ATI crank hub systems for maximum drivetrain flexibility

ATI Performance Products has been a leader in high-performance driveline components since 1961, manufacturing Super Dampers, racing transmissions, torque converters, and related components at their facility near Baltimore, Maryland. The ATI917076 Super Damper is built to outperform OEM harmonic balancers in demanding race and street performance environments.
