Product Description

The ATI 918456 Super Damper is engineered specifically for Honda D-Series engines installed in Civic, CRX, Del Sol, and Integra platforms from 1990 to 2000. Its 10% underdrive serpentine pulley reduces accessory speed - extending the lifespan of engine components - while preserving harmonic control across the RPM range.

Featuring an aluminum shell with a steel hub, this damper includes a 5.5-inch 4-rib pulley compatible with the factory belt layout. With laser-etched 360° timing marks, a dual-ring elastomer design, and SFI 18.1 certification, this part is built for high-rpm street or racing applications of up to 750 HP. Mounting hardware is not included.

Fitment is confirmed through 2000; coverage beyond 2000 is unverified at this time.
