ATI Performance Products ATI918040 Super Damper Harmonic Balancer 6.325 Inch Nissan L24 L26 L28

The ATI Performance Products ATI918040 Super Damper is a high-performance harmonic balancer precision-engineered for Nissan L24, L26, and L28 inline-six engines. This advanced damper provides superior torsional vibration control across the entire RPM range, protecting your crankshaft from damaging harmonic vibrations that can lead to bearing wear and component failure in high-performance applications.

Key Features:

• 6.325-inch outside diameter aluminum construction for reduced rotational mass
• 3-ring elastomer design for superior vibration dampening at all RPM levels
• Integral V-belt pulley with 3.200-inch bolt circle for factory accessory compatibility
• SFI 18.1 certified for racing and competition use
• Laser-etched 360-degree timing marks for precise tuning
• Black zinc chromate finish for corrosion resistance
• Internal balance design
• Steel hub construction (2.4 lbs) with aluminum shell (3.9 lbs)
• Total weight: 7.55 lbs

ATI's patented Super Damper technology uses computer-machined grooves and proper durometer O-rings to contain the steel inertia weight, providing balanced dampening that far exceeds factory dampers and non-dampened pulleys. Ideal for street, strip, or forced induction builds on classic Datsun 240Z, 260Z, and 280Z models. The damper is fully rebuildable using genuine ATI components for long-term reliability. Sold individually; mounting hardware not included.
