Cadillac CTS-V Crankshaft Damper - ATI - 7.48in - Alum LW - 6 Groove - LSA - 09-15 is a direct-fit, lightweight ATI crank damper designed for LSA-powered CTS-V models. This damper replaces the factory unit with a precision-made aluminum pulley intended for reliable accessory drive compatibility.

Built by ATI for street and performance applications, the 7.48-inch aluminum lightweight damper retains the correct 6-groove accessory interface while reducing rotating mass compared to heavier cast units. It is made to fit 2009–2015 Cadillac CTS-V LSA engines and is supplied excluding the supercharger (SC) pulley — verify pulley application before purchase. The construction and balance process are engineered to preserve proper crank vibration control while offering a lower-mass pulley for crisper throttle response and reduced parasitic loss.

• 6-groove accessory interface (matches factory belt configuration)
• Designed specifically for LSA engines in 2009–2015 CTS-V
