ATI Damper - 7.074in - Steel - Chevy BB - Chrysler Front - w/Blower - 6 Bolt - 3 Ring - 2nd 1/4 Key

This ATI 918871E crankshaft damper is a well-built component designed for Chevy Big Block and Chrysler engines that are equipped with a blower. You'll receive the damper itself, which features a 7.074-inch diameter and is constructed from steel for durability. It's configured for a 6-bolt crank pulley setup and includes three rings for harmonic balancing, along with provisions for a second 1/4-inch keyway to ensure secure timing.

ATI is known for making solid components for performance applications, and this damper is no exception. The steel construction helps it withstand the stresses of a high-performance engine, especially when a blower is involved. The multi-ring design is key to its function, as it helps to cancel out torsional vibrations that can occur at the crankshaft, particularly at higher RPMs. This helps protect your engine's internal components and can lead to a smoother running engine.

When installing this damper, ensure you have the correct tools and follow the manufacturer's recommended procedures for proper alignment and keyway engagement. This damper is a critical part of your engine's front-end assembly, especially in boosted applications where harmonic issues can be more pronounced.
