ATI Damper - 7.074in - Steel - Chevy SB/90 Deg V6 - Blower & BBC Seal - 6 Bolt - Dual Key - 3 Ring

This is the ATI 918869 crankshaft damper, a well-built steel unit designed for Chevy Small Block and 90-degree V6 engines. It's specifically configured with a blower and BBC seal, featuring a 6-bolt pattern and dual keyways for secure timing. This damper is crucial for reducing torsional vibrations from the crankshaft, which can otherwise lead to premature engine wear and potential failure, especially in high-performance applications.

Built from solid steel, this damper is made to handle the stresses of boosted engines and larger displacement BBC applications. The 7.074-inch diameter is a common size for many performance builds, and the dual keyway design offers an extra layer of security against keyway shear, a common issue when power levels increase. The three-ring design is often used for precise timing marks, making it easier to degree your camshaft or check ignition timing accurately.

When installing a damper like this, ensure you have the proper puller and installer tools to avoid damaging the crankshaft snout. It's a critical component for engine longevity and consistent performance, especially if you're running a blower or a BBC-style seal setup.
