ATI Performance Products ATI917469 Super Damper Harmonic Balancer 6.78 Inch Mopar

The ATI Performance Products ATI917469 Super Damper is a high-performance harmonic balancer engineered specifically for Dodge Neon SRT-4 and PT Cruiser 2.4L turbo engines. This patented crankshaft damper eliminates harmful torsional crankshaft vibrations that can rob horsepower and cause engine damage at high RPM.

Key Features:

• 6.78-inch outside diameter with aluminum construction
• 3-ring elastomer design with steel inertia weight for superior damping
• Dual 4-groove serpentine belt configuration for OEM accessory drive compatibility
• Internal balance design for proper engine harmonics
• Black anodized finish with laser-engraved 360-degree timing marks
• Exceeds SFI 18.1 certification requirements for racing applications
• Rebuildable and tunable for maximum longevity
• Total weight: 4.50 lbs with 2.40 lb hub weight

Unlike rubber-bonded OEM dampers that deteriorate over time, the ATI Super Damper uses precision-machined grooves and proper durometer O-rings to maintain consistent performance. This design is proven in Winston Cup competition and drag racing, providing effective damping at all RPM ranges from idle to redline. The damper is especially critical for turbocharged applications where increased cylinder pressures create greater torsional stress on the crankshaft.
