ATI Performance Products ATI918476 Super Damper Harmonic Balancer Honda B-Series - 5.5

The ATI Performance Products ATI918476 Super Damper is a high-performance harmonic balancer engineered specifically for Honda B-Series engines, including B16, B18, B20, and Type-R (B18C5) applications. This 5.5-inch street damper is designed as a direct OEM replacement for Acura Integra B18 and Honda CRV B20 engines, rated for high-horsepower street use up to 500 HP.

Key Features:

• Patented "damper within a damper" design eliminates harmful torsional crankshaft vibrations
• 3-ring elastomer construction with computer-machined grooves for optimal vibration control
• SFI 18.1 certified for racing applications
• Laser-engraved 360-degree timing marks for precise tuning
• 5.67-inch outside diameter with steel construction and black zinc chromate finish
• Machined multi-groove pulleys accommodate factory serpentine belt systems with A/C, alternator, and power steering
• Includes removable serpentine power steering pulley for 1994 and newer B-Series applications
• Internally balanced design
• Weighs 3.6 pounds for reduced rotational mass

This Super Damper is tunable, rebuildable, and extremely efficient across the entire RPM range. The aluminum and steel construction with steel inertia weight provides superior damping performance compared to stock rubber dampers that deteriorate over time. Whether you're building a turbocharged street machine or upgrading your naturally aspirated B-Series engine, the ATI918476 delivers professional-grade crankshaft protection and improved engine performance.

Note: V-groove power steering pulley (916769) available separately for earlier B-Series applications (1990-1993). Mounting hardware sold separately.
