ATI Performance Products ATI917754 Super Damper Harmonic Balancer Nissan - 300ZX VG30

The ATI Performance Products Super Damper is a high-performance harmonic balancer engineered specifically for the Nissan 300ZX VG30 engine. This precision-manufactured damper provides superior protection against torsional crankshaft vibrations at all RPM levels, addressing a critical weakness in factory dampers and non-dampened pulleys that leave high-performance engines vulnerable to damage.

Key Features:

• 5.5-inch diameter aluminum construction with black zinc chromate finish
• Elastomer-based damping system with steel inertia weight for balanced vibration control
• Rated for street and race applications up to 600-800 horsepower
• Laser-etched 360-degree timing marks for precise tuning
• SFI 18.1 certified for competition use
• Internally balanced design for proper crankshaft operation
• Fully rebuildable and tunable for extended service life

Underdrive Configuration:

• Power steering pulley: 6% underdrive
• Alternator and water pump: 12% underdrive
• OEM serpentine groove locations maintained

The patented ATI Super Damper utilizes computer-machined grooves to retain proper durometer O-rings, creating an elastomer construction that effectively dampens harmful crankshaft vibrations throughout the RPM range. Unlike factory dampers that deteriorate over time, this Super Damper is rebuildable, providing infinite years of reliable service. The three-ring design and aluminum shell construction keep weight to just 3.60 pounds while maintaining exceptional durability. Mounting hardware sold separately.
