ATI Damper - 6.325in - Alum - Ford SB & 6 Cyl - Chevy Frt - 3in Long - C-Timing - 3 Ring

This is the ATI 6.325 inch aluminum crankshaft damper, part number 917661. It's designed to fit Ford small block engines and Chevrolet 6-cylinder engines with a front seal. This damper is 3 inches long and features a 'C-Timing' mark and three separate rings for enhanced timing accuracy.

Crankshaft dampers are crucial for absorbing torsional vibrations that occur during the combustion cycle. Without a properly functioning damper, these vibrations can lead to premature wear on your crankshaft, bearings, and other critical engine components. ATI dampers are well-built using aluminum for a lighter weight compared to stock steel units, and their multi-ring design offers a notable improvement in timing stability. The three rings on this damper provide distinct reference points for your timing light, making it easier to achieve precise ignition timing, especially in modified or high-performance applications.

This damper is a solid option if you're looking to replace a worn-out unit or upgrade your engine's timing stability. Ensure you have the correct front seal configuration for your specific engine application before installation.
