ATI Performance Products 918525 Super Damper Harmonic Balancer Toyota Inline-6

The ATI Performance Products 918525 Super Damper is a high-performance harmonic balancer engineered specifically for Toyota inline-6 cylinder engines. This patented crankshaft damper is designed exclusively for high-performance applications, effectively eliminating torsional crankshaft vibrations at all RPM levels to protect against parasitic horsepower loss and engine harmonics.

Key Features:

• 5.67-inch outer diameter aluminum shell with 3-ring design for superior damping
• Steel crankshaft hub with inner shell for durability and strength
• Internal engine balance configuration
• SFI 18.1 certified for competition use
• Laser-engraved 360-degree timing marks for precise tuning
• Black zinc chromate finish for corrosion resistance
• Computer-machined grooves retain proper durometer O-rings dyno-tested for each application
• Steel inertia weight (2.2 lbs) with 3-ring design
• Direct replacement for OEM harmonic balancer

The ATI Super Damper uses a unique elastomer-based damping system with eight computer-machined grooves that retain specialized O-rings, providing superior vibration control compared to conventional rubber-style dampers. The aluminum outer shell weighs 3.60 lbs, while the steel hub adds approximately 2.6 lbs, creating optimal inertia characteristics for high-performance engine protection. Whether you're building a race engine or upgrading your street performance, the ATI 918525 delivers professional-grade crankshaft protection and improved engine reliability.
