ATI Damper - 6.78in - Alum - 6 Grv - 10 Percent UD - LS1/LS2 - F & V Body - No A/C - 3 Ring

ATI is well-known for making robust performance engine components, and this crankshaft damper is a prime example of their focus on durability and function. This 6.78-inch aluminum damper is built for LS1 and LS2 engines found in F and V body vehicles, specifically those without A/C. It features a 10 percent underdrive pulley and a 3-ring design with 6 grooves, which helps manage torsional vibrations and ensures consistent operation.

The aluminum construction keeps the weight down while providing the strength needed to handle the stresses of a performance engine. The 6-groove design offers flexibility for accessory belt setups, and the 3-ring configuration is a key part of ATI's approach to controlling crankshaft harmonics. This damper is a solid option for LS engine builds where reliable performance and vibration control are important.
