ATI Damper - 7.48in - Alum LW - 6 Grv - LS1-2-3-6 & L76 - 97-13 - Y Body & SS & G8 - No A/C - 3 Ring

This ATI crankshaft damper, part number 917303, is a well-built component designed for specific GM LS engines. You get the 7.48-inch aluminum damper itself, featuring a 6-rib serpentine belt groove configuration and a 3-ring design. It's intended for LS1, LS2, LS3, LS6, and L76 engines manufactured between 1997 and 2013, specifically for Y-Body, SS, and G8 platforms that do not have air conditioning.

Crafted from aluminum, this damper is lighter than stock, which can help reduce rotational mass at the crankshaft. The multi-ring design is ATI's approach to controlling torsional vibrations, which are inherent in V8 engines. By dampening these vibrations, you're helping to protect the crankshaft and other engine components from excessive stress, especially in modified applications or under demanding use. The 6-rib groove setup means it's ready to work with a 6-rib serpentine belt system.

When installing this damper, ensure you have the correct tools to properly seat it on the crankshaft snout. It's a direct replacement for applications without A/C, so verify your vehicle's configuration before ordering.
