ATI Damper - 5.67in - Alum - 6 Grv - 25 Percent UD - LS1/LS2 - F & V Body - No A/C - 1Pc

This ATI crankshaft damper is a well-built component designed for LS1 and LS2 engines, specifically for F-body and V-body applications without A/C. It's a 5.67-inch aluminum damper featuring 6 grooves and a 25 percent underdrive pulley system. This damper helps to control torsional vibrations from the crankshaft, which is crucial for engine longevity and smooth operation, especially in performance applications.

Crafted from aluminum, this damper is lighter than cast iron alternatives, contributing to reduced rotational mass. The 6-groove design allows for multiple accessory belt configurations, offering flexibility for custom setups. The 25 percent underdrive means the accessories driven by the crankshaft pulley will spin at a slower speed than the crankshaft itself, which can reduce drag on the engine and potentially free up a small amount of horsepower. This damper is a direct replacement for specific LS1/LS2 configurations, ensuring a proper fit.

When installing this damper, ensure you have the correct tools to remove the old unit and properly seat the new one. It's important to verify that your specific engine setup is compatible with the 'No A/C' designation and the 1-piece design.
