ATI Performance Products ATI916777 Super Damper Harmonic Balancer

The ATI Performance Products ATI916777 is a high-performance Super Damper torsional crankshaft damper (harmonic balancer) engineered for demanding street, strip, and racing applications. ATI's Super Damper line is the industry standard in crankshaft vibration dampening, trusted by professional racers and engine builders worldwide.

Unlike OEM rubber-bonded dampers that degrade over time and lose effectiveness under heat and high RPM, the ATI Super Damper uses a precision-tuned elastomer ring dampening system housed in a billet aluminum shell. This design provides consistent, reliable torsional vibration control that helps protect your crankshaft and rotating assembly from damaging harmonic stress.

Key Features:

• Precision-machined billet aluminum construction for reduced rotating weight
• Elastomer-based torsional dampening system — no rubber bond to fail
• SFI 18.1 certification for sanctioned racing applications
• Precision-engraved timing marks for accurate ignition timing setup
• Rebuildable and re-tunable design for long service life
• Manufactured in the USA by ATI Performance Products

The ATI Super Damper is a direct upgrade over stock and aftermarket rubber dampers, offering superior durability and protection for high-performance and high-revving engine builds. SFI certification makes it legal for use in many sanctioned drag racing events.
