ATI Performance Products ATI951388 Super Damper Harmonic Balancer

The ATI Performance Products ATI951388 Super Damper is a high-performance harmonic balancer engineered to reduce crankshaft torsional vibration and protect your engine under demanding racing and high-performance street conditions. ATI's Super Dampers are trusted by professional racers and performance enthusiasts worldwide for their superior vibration damping characteristics and proven durability.

Unlike factory rubber-bonded harmonic balancers that can degrade over time, ATI Super Dampers use a precision-machined aluminum housing with an inertia ring tuned to the specific crankshaft's resonant frequency. This design provides consistent, effective damping throughout the RPM range, helping to extend crankshaft and engine component life.

Key Features:

• Precision-machined billet aluminum construction for strength and light weight
• Tuned inertia ring for optimal torsional vibration damping
• SFI 18.1 specification compliant — required for many sanctioned racing events
• Resists heat, oil, and chemical exposure better than OEM rubber-bonded units
• Precision balancing for smooth operation at high RPM
• Accepts standard timing pointer for accurate ignition timing
• Rebuildable and re-tunable design for long service life

ATI Performance Products has been manufacturing Super Dampers since 1966 and is the industry leader in crankshaft damper technology. The ATI951388 is designed as a direct-fit performance replacement, making installation straightforward. Always verify fitment using ATI's application guide before installation.
