ATI Performance Products ATI918584 Super Damper Harmonic Balancer Aluminum - 5.67 7-Groove VQ35HR VQ37VHR

The ATI Performance Products ATI918584 Super Damper is a high-performance harmonic balancer engineered specifically for Nissan VQ35HR and VQ37VHR engines. This precision-manufactured damper utilizes ATI's patented design to effectively control torsional crankshaft vibrations, protecting your engine while maximizing performance at all RPM ranges.

Key Features:

• 5.67-inch diameter with 7-groove serpentine belt configuration
• Lightweight aluminum construction with hardcoated finish reduces rotational mass
• 4% underdrive ratio optimized for street performance applications
• One-piece design for superior strength and reliability
• Exceeds SFI 18.1 certification standards for competition use
• Fully rebuildable and tunable for long-term durability
• Laser-engraved 360-degree timing marks for precise tuning
• Black zinc chromate finish for corrosion resistance

The ATI Super Damper eliminates harmful torsional vibrations that can rob horsepower and damage engine components. Unlike rubber-based OEM dampers that deteriorate over time, the ATI Super Damper maintains consistent performance throughout its service life. The aluminum shell reduces rotating weight compared to steel dampers while still providing exceptional damping efficiency. This damper is ideal for high-performance street builds, forced induction applications, and racing engines where precise crankshaft control is essential.
