Subaru Super Dampers

ATI Performance Products, Inc. is proud to introduce its renowned Super Damper
for Subaru EJ20, EJ22 and EJ25 engines -- Part # 917991. Unlike undampened
underdrive 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 a dual four-groove serpentine belt drive 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.

The patented ATI Super Damper is the only damper designed exclusively for high performance engines:
- Eliminates torsional crankshaft vibrations
- Exceeds SFI 18.1 specs
- Laser engraved timing marks
- Black zinc chromate finish

Damper Components: Hub, Outer Shell, Inertia Ring and Bolt Kit.
