ATI Damper - 6.78in - AL - 6 Grv - 10 Per UD - LS1/2/3/6 - 97-13 - Y Body - No A/C - AL Hub - 3 Ring

What you get with this ATI Damper kit is a 6.78-inch aluminum crankshaft damper designed for LS1, LS2, LS3, and LS6 engines. This particular damper is set up for a 10% underdrive and features six grooves for accessory belts, along with an aluminum hub and three rings. It's intended for use on Y-body vehicles from 1997 to 2013 that do not have air conditioning.

ATI is well-known for making robust engine components, and this damper is built to handle the stresses that come with higher-performance LS engines. The aluminum construction helps keep rotational mass down, while the multi-ring design and 10% underdrive pulley setup are key for managing engine harmonics and accessory drive speeds. This can lead to improved engine longevity and more consistent operation, especially when you're pushing the engine harder or have modified it. The six-groove setup gives you flexibility if you're running multiple accessories or need to adjust belt routing.

When installing this damper, remember that it's a critical component for engine health. It helps absorb torsional vibrations from the crankshaft, preventing damage over time. Make sure to follow the manufacturer's installation instructions carefully, as proper alignment and securing the damper are essential for it to do its job effectively. This damper is a solid choice for LS engine builds where reliability and performance are important.
