ATI Super Damper - Nissan SR20DET RWD

ATI's Super Damper for Nissan SR20 RWD engines

Unlike undampened underdrive crank pulleys, which offer no protection to high-performance engines, the ATI Super Damper provides balanced dampening of torsional crankshaft vibrations at all RPM levels. The ATI Super Damper comes with laser-etched timing marks and is a direct replacement for the OEM unit. The ATI Super Damper is a critical component for all high performance cars to help protect against engine harmonics and features four-groove and five-groove serpentine belt drives on the outer shell to utilize the factory serpentine belt set-up. All ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition use.

Features:

- Eliminates torsional crankshaft vibrations
- Exceeds SFI 18.1 specs
- Black zinc chromate finished
- Tunable, rebuildable, and extremely efficient at ALL RPM
- Laser engraved 360° timing marks

Note: Honing may be required if using aftermarket crank due to tolerance differences compared with OEM.
