ATI Performance Products 918854 Super Damper Harmonic Balancer 7.5" 6-Groove for Cadillac CTS-V LSA

The ATI Performance Products 918854 Super Damper is a high-performance harmonic balancer engineered specifically for 2009-2015 Cadillac CTS-V applications equipped with the supercharged LSA 6.2L V8 engine. This precision-machined damper features a 7.5-inch diameter lightweight aluminum construction that reduces rotational mass while providing superior crankshaft harmonic dampening compared to OEM rubber-style balancers.

Key Features:

• 7.5-inch diameter aluminum shell with internal elastomer dampening system
• 6-groove serpentine belt design for stock accessory drive compatibility
• Lightweight construction reduces parasitic drag and improves throttle response
• Rebuildable design extends service life and reduces long-term costs
• SFI 18.1 certified for racing applications
• CNC-machined from billet aluminum for precise balance and durability
• Laser-etched timing marks for accurate ignition timing adjustment

ATI Super Dampers utilize a patented elastomer bond system that absorbs harmful crankshaft vibrations across the entire RPM range, protecting engine bearings and reducing stress on internal components. Unlike OEM rubber dampers that deteriorate over time, the rebuildable design allows the elastomer to be replaced, making this a long-term performance solution. This damper is ideal for street performance, road racing, and drag racing applications on modified LSA engines producing elevated power levels.
