ATI Performance Products 918562 Super Damper Harmonic Balancer for Toyota Supra 2JZ-GTE

The ATI Super Damper is a high-performance harmonic balancer designed exclusively for demanding engine applications, specifically engineered for 1994-1998 Toyota Supra 3.0L 2JZ-GTE turbocharged engines. This SFI 18.1 certified damper features a 6.780-inch outside diameter and utilizes an aluminum shell with steel hub construction for optimal strength and reduced rotating mass.

Key Features:

• Eliminates torsional crankshaft vibrations across all RPM ranges for improved engine longevity
• Exceeds SFI 18.1 specifications for competition use and high-performance street applications
• Laser-engraved 360-degree timing marks for precise engine tuning and diagnostics
• 15% overdriven pulley with 6-rib serpentine belt design for increased alternator output
• Computer-machined grooves retain proper durometer O-rings that are dyno-tested for each application
• Tunable, rebuildable, and extremely efficient design for long-term serviceability
• Black zinc chromate finish for corrosion resistance and professional appearance

Technical Specifications:

• Application: 1994-1998 Toyota Supra JZA80 2JZ-GTE Twin Turbo
• Outside Diameter: 6.780 inches
• Construction: Aluminum outer shell with steel hub and inertia weight
• Balance Type: Internal balance

• SFI Certification: 18.1

The patented ATI Super Damper design uses elastomer O-rings between the inertia weight and shells to effectively dampen harmful crankshaft vibrations that can lead to engine damage in high-performance applications. Unlike OEM rubber-bonded dampers that deteriorate over time, the ATI unit is rebuildable and maintains consistent performance throughout its service life. A longer serpentine belt is required due to the 15% overdrive design, with Gates K060775 being the recommended replacement belt.
