This item does not qualify for promotional discounts or wholesale pricing.
ATI Performance Products, Inc. is proud to introduce its all new Super Damper (Part # 917781) designed for the 1963-1982 Corvette 327/350 w/hydraulic lifters & 1984-1991 Corvette L83/L98 engines for both street and high performance racing applications. The new steel-shell, steel-hub damper is a direct fit replacement for the stock OEM unit and is capable of handling a wider variety of driving habits specific to individual Corvette owners. OEM dampers are optimally tuned to a narrow band of perceived normal driving conditions and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine.
The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chevy engines. Check out these 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
- 6.325" Diameter
- 6.00 lbs total weight, 2.40 lbs inertia weight
- Designed for engines that are internally balanced
ATI Performance Products, Inc. specializes in producing and maintaining high performance harmonic balancers for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail, and rigorous testing under race conditions.
