ATI Performance Products ATI918620 Super Damper Harmonic Balancer Corvette - 7.65 LS7

The ATI Performance Products ATI918620 Super Damper is a high-performance harmonic balancer designed specifically for GM LS7 engines in Y-Body Corvettes, Gen 5 Z28 Camaro, and LS3 Grand Sport manual transmission applications. This precision-engineered damper measures 7.65 inches in diameter and features OEM sizing for direct bolt-on installation.

Key Features:

• Lightweight aluminum construction reduces rotational mass while maintaining superior damping performance
• Dual groove configuration with 8-groove and 4-groove serpentine belt pulleys for complete accessory drive compatibility
• Two-ring elastomer design (2RG) provides optimal harmonic vibration control across the RPM range
• SFI 18.1 certified for competition use (racing applications)
• OEM diameter sizing ensures proper fitment with stock accessory drives and timing covers
• CNC-machined from high-grade aluminum alloy for precise balance and durability

ATI Super Dampers utilize a unique internal elastomer system that absorbs and dissipates harmful crankshaft vibrations that can cause premature engine wear and failure. The aluminum construction offers significant weight savings over steel dampers while the dual-ring design maintains excellent damping characteristics for both street and track applications. This damper is ideal for high-performance LS7 builds, forced induction setups, and racing applications where engine longevity and reliability are critical.
