ATI Damper - 6.325in - Steel - Ford SB & 6 Cyl - 4 Bolt OEM - 3.35in Long - C-Timing - 3 Ring

This is the ATI 6.325-inch steel crankshaft damper, part number 918920, designed for Ford small block and 6-cylinder engines. It's built with a 4-bolt OEM style configuration and is 3.35 inches long, featuring a C-timing mark and three separate rings. This damper plays a crucial role in reducing torsional vibrations from the crankshaft, which can otherwise lead to premature wear on your engine's internal components.

ATI is known for making well-built performance parts, and this damper is no exception. The steel construction offers solid durability, while the three-ring design is a notable feature that helps to absorb a wider range of vibration frequencies compared to single-ring designs. This improved vibration control can lead to a smoother running engine and potentially extend the life of your crankshaft and other rotating assembly parts. The C-timing mark is also a practical addition for setting ignition timing accurately during engine setup or tuning.

When installing this damper, ensure you have the correct tools to properly seat it on the crankshaft snout. It's designed to fit Ford SB and 6-cylinder applications with a 4-bolt OEM style pulley setup. Proper installation is key to its effectiveness in managing crankshaft harmonics.
