The ATI 7.425-inch steel lightweight damper for LS-family engines (LS1/2/3/6 and L76) used in 1997–2013 Y-Body, SS and G8 platforms features an eight- and four-groove face option and a three-ring damping arrangement. Steel construction provides mass and durability while the tuned rings control crank harmonics for these GM V8 applications where a heavier damper profile is acceptable or preferred.
