ATI Damper - 5.50in - Alum - 8 Grv - Ecotec - 12 Percent UD - 800HP or Less - 1Pc - 3 Ring

This ATI damper kit includes the 5.50-inch aluminum crankshaft damper, featuring an 8-groove pulley system and a 12 percent underdrive design. It's constructed with a 3-ring setup, intended for Ecotec engines and rated for applications up to 800 horsepower. This damper is designed to help reduce torsional vibrations from the crankshaft, which is crucial for engine longevity and smooth operation, especially in modified Ecotec engines.

Crafted from aluminum, this damper is lighter than steel alternatives, contributing to reduced rotational mass. The 12 percent underdrive means the accessory pulleys will spin slightly slower than the crankshaft, which can help reduce accessory drag and potentially improve horsepower at the wheels. The 3-ring design offers a robust solution for managing crankshaft harmonics, a common concern in higher-performance Ecotec builds. This damper is a well-built component for those looking to enhance their engine's reliability and performance.
