ATI Performance Products ATI918895 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI918895 Super Damper is a high-performance elastomer-style crankshaft harmonic balancer engineered to protect your engine from the destructive effects of torsional vibration. ATI Super Dampers are built using a precision-machined billet aluminum hub with one or more inertia rings tuned to a specific frequency, effectively absorbing and dissipating crankshaft harmonics that can lead to premature bearing wear, broken cranks, and power loss.

Unlike OEM rubber-bonded balancers that can degrade over time, ATI Super Dampers use a highly durable elastomer material that maintains consistent damping characteristics across a wide RPM range — making them a trusted choice in street performance, road racing, drag racing, and high-horsepower builds.

Key Features:

• Precision-machined billet aluminum hub and inertia ring(s)
• High-durability elastomer damping material for long service life
• Tuned to specific crankshaft torsional frequencies for maximum protection
• SFI certification (where applicable) for sanctioned racing events
• Includes timing marks for accurate ignition timing reference
• Direct bolt-on replacement designed to OEM dimensional specifications
• Compatible with stock and aftermarket front accessory drive setups

ATI Performance Products has been a leader in performance drivetrain components since 1966, and the Super Damper line reflects decades of engineering expertise. The ATI918895 is designed for enthusiasts and racers who demand reliable crankshaft protection without sacrificing performance.
