ATI Performance Products ATI916433 Super Damper Crankshaft Harmonic Balancer

ATI Performance Products ATI916433 is a high-performance Super Damper crankshaft harmonic balancer engineered to reduce torsional vibration and protect your engine's crankshaft, bearings, and rotating assembly under demanding performance and racing conditions.

ATI Super Dampers are manufactured in the USA and are SFI 18.1 certified, making them legal for use in sanctioned racing events. Unlike rubber-bonded OEM-style dampers that can slip, degrade, or fail under high RPM and heat, ATI Super Dampers use precision steel shells bonded with elastomer rings specifically tuned to the resonant frequency of your engine combination.

Key Features:

• SFI 18.1 certified for sanctioned racing use
• Reduces torsional crankshaft vibration to protect engine components
• Precision-machined billet steel construction
• Elastomer-tuned damping for specific engine resonance frequencies
• Will not slip or degrade like rubber OEM-style dampers
• Includes timing marks for accurate ignition timing reference
• Made in the USA by ATI Performance Products
