ATI Performance Products ATI916998 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI916998 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration at the crankshaft, protecting your engine from damaging harmonic stress during high-RPM operation. ATI Super Dampers are a trusted choice among professional racers and performance enthusiasts who demand reliability and precision from their rotating assembly components.

Unlike stock rubber-bonded balancers that degrade over time and lose their dampening effectiveness, ATI Super Dampers utilize a precision-machined billet aluminum shell with an elastomer ring and inertia ring tuned specifically for the target application. This construction ensures consistent harmonic control across the RPM range, whether on the street or at the track.

Key Features:

• Precision-machined billet aluminum construction for superior strength and durability
• Tuned elastomer dampening ring for effective torsional vibration control
• SFI 18.1 certification for sanctioned racing applications
• Laser-etched timing marks for accurate ignition timing
• Replaces worn or stock harmonic balancers with a performance-focused upgrade
• Designed for high-RPM performance and endurance

ATI Performance Products has been a leader in performance drivetrain components since 1966, and the Super Damper line reflects decades of engineering expertise. The ATI916998 is built to exacting tolerances, making it an ideal upgrade for engine builds where protecting the crankshaft and maintaining timing accuracy are top priorities.
