ATI Performance Products ATI916311 Super Damper Harmonic Balancer

The ATI Performance Products ATI916311 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's rotating assembly. ATI Super Dampers are among the most trusted dampers in racing and high-performance street applications, built to outperform OEM rubber-bonded balancers that degrade over time.

Unlike factory harmonic balancers that rely on a rubber ring bonded between two metal rings, the ATI Super Damper uses a precision-machined steel shell with a series of inertia rings and O-rings that absorb and dissipate torsional energy across a broad RPM range. This design remains effective for the life of the damper and does not degrade with heat or age.

Key Features:

• Precision-machined from high-strength steel for durability and balance
• Multi-ring O-ring damping design for broad-spectrum torsional vibration control
• SFI 18.1 certified for sanctioned racing use
• Does not degrade over time like OEM rubber-bonded dampers
• Laser-etched timing marks for accurate ignition timing
• Designed for performance street, strip, and competition applications

ATI Super Dampers are manufactured in the USA and are a direct upgrade over stock harmonic balancers, offering superior protection for high-horsepower and high-RPM engines. The ATI916311 is engineered to exact tolerances for a precise OEM-style installation with performance-level results.
