ATI Damper – 6.78in – Aluminum – (3) 4 Groove – 800 HP+ (1984 – 1996 Nissan 300ZX V6) – ATI917755

High-Output Aluminum Super Damper for 1984–1996 Nissan 300ZX V6 Engines

The ATI 6.78-inch Aluminum Super Damper (part ATI917755) is built to control crankshaft harmonics in high-power Nissan VG-series V6 engines found in the 1984–1996 300ZX. Designed for builds making 800 horsepower and beyond, this lightweight damper uses a (3) 4-groove pulley layout and advanced aluminum construction to deliver strength, precision, and improved throttle response under extreme load. It’s the proven choice for serious turbo or track applications that demand reliability and balance at high RPM.

Performance Highlights

  • 6.78-inch outer diameter for superior harmonic absorption in high-RPM VG engines
