Use this sprocket on listed Buick, Chevrolet, GMC, Pontiac, Saturn, and Saab applications, including 2015-2017 Chevrolet Equinox exhaust, 2015-2017 GMC Terrain exhaust, and 2012-2017 Buick Verano. Standard Ignition VVT524 is also listed for 2006-2011 Chevrolet HHR exhaust and 2006-2009 Pontiac Solstice exhaust applications.

What It Helps Address

• Rough or unstable idle related to worn VVT components
• Loss of horsepower or torque from incorrect cam timing
• Excessive timing noise from worn sprocket tooth profiles
• Performance issues caused by leakage or lash in the VVT system
• Reduced fuel efficiency tied to inconsistent valve timing
