ATI Performance Products ATI917753 Super Damper Harmonic Balancer for Nissan RB26DETT

The ATI Performance Products ATI917753 Super Damper is a high-performance harmonic balancer designed exclusively for Nissan Skyline R33 and R34 GT-R RB26DETT engines. This patented damper is engineered to eliminate harmful torsional crankshaft vibrations that cause parasitic horsepower loss and premature engine wear, making it ideal for street and race applications up to 1000 horsepower.

Key Features:

• Exceeds SFI 18.1 certification standards for competition use
• Steel shell construction with 2-ring elastomer design for maximum vibration dampening
• Tunable, rebuildable, and extremely efficient at all RPM ranges
• Laser-engraved 360-degree timing marks for precision tuning
• Black zinc chromate finish for corrosion resistance
• Direct bolt-on replacement for OEM damper
• Includes billet aluminum water pump pulley for proper clearance
• 7-rib serpentine design with 7.05-inch diameter

Each combustion event creates severe torque spikes that twist the crankshaft, causing torsional vibration. The ATI Super Damper controls these destructive vibrations to protect bearings and the crankshaft while recovering lost horsepower. This damper features computer-machined grooves that retain proper durometer O-rings between steel inner and outer shells, providing superior dampening across the entire RPM range. Rated for engines producing up to 1000 horsepower, this is an essential upgrade for any high-performance RB26DETT build.
