ATI Damper - 7.48in - Alum - 6 Grv - LS1/2/3/6/L76 97-13 - Y Body & SS & G8 - 28T 8mm HTD - 3 Ring

When you're working on your LS engine, especially one that's been modified or sees hard use, controlling torsional vibrations is key to its longevity and performance. This ATI Damper, part number 917304, is designed specifically for LS1, LS2, LS3, LS6, and L76 engines from 1997 through 2013. It's also noted for fitment on Y-Body, SS, and G8 models within that timeframe. What you get in this package is the 7.48-inch diameter aluminum crankshaft damper itself, ready to be installed.

This damper is constructed from aluminum, making it lighter than a stock cast iron unit, which can be beneficial for overall engine balance. It features six grooves for accessory belts and a three-ring design, indicating a robust construction aimed at absorbing harmful crankshaft harmonics. The 28-tooth, 8mm HTD (High Torque Drive) pulley system is integrated into the damper, often used for supercharger or other accessory drives where precise belt engagement is critical. ATI is known for making well-built performance components, and this damper is no exception, offering a solid option for builders looking to protect their investment and ensure smooth operation.

Installing a damper like this is a critical step when rebuilding or significantly upgrading an LS engine. It's designed to be a direct replacement for the factory unit, though proper installation tools and procedures should always be followed to ensure it's seated correctly and torqued to spec. This damper is a substantial piece of equipment that plays a vital role in the health of your engine's rotating assembly.
