ATI Performance Products ATI917028 Super Damper Crankshaft Harmonic Balancer

The ATI Performance Products ATI917028 Super Damper is a high-performance crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's crankshaft, bearings, and rotating assembly. ATI Super Dampers are the industry standard in professional motorsports and high-performance street applications, trusted by racers and engine builders worldwide.

Unlike factory rubber-bonded balancers that degrade over time and lose effectiveness, the ATI917028 utilizes a precision-tuned elastomer dampening system housed in a billet aluminum shell. This design provides consistent, reliable vibration dampening across a wide RPM range, helping to extend engine life and improve performance.

Key Features:

• Precision-machined billet aluminum construction for strength and light weight
• Tuned elastomer dampening element for superior torsional vibration control
• SFI 18.1 certification for sanctioned racing applications
• Laser-etched degree markings for precise ignition timing
• Direct OEM replacement fit — no modification required
• Resists heat, oil, and chemical degradation
• Rebuildable and re-tunable design for long service life

ATI Super Dampers are manufactured in the USA to strict tolerances and are a direct upgrade over stock harmonic balancers. The ATI917028 is an ideal choice for performance builds requiring reliable crankshaft protection and accurate timing reference marks.
