Standard Ignition VVT549 is a direct-fit engine variable valve timing sprocket for the intake right side on a wide range of GM vehicles. It is built to restore accurate cam timing, smooth rough idle, and recover lost drivability in applications such as the Buick Enclave, Chevrolet Traverse, and GMC Acadia.

Key Features

• Engine Variable Valve Timing sprocket for intake right applications
• Precision-machined for accurate variable valve timing control
• OE-matching sprocket tooth profile for quiet operation
• Designed to reduce leakage and lash for improved performance
• 100% end-of-line tested to meet or exceed OE performance targets
• OE-style installation bolt included where applicable

Detailed Description

Standard Ignition VVT549 is an OE replacement VVT sprocket engineered for direct fitment on supported GM platforms. By helping restore proper cam phasing, this part can recover horsepower and torque delivery, improve engine efficiency, and reduce emissions. It is a practical replacement for worn or noisy intake right variable valve timing components on vehicles including the Chevrolet Impala, Cadillac CTS, and Buick LaCrosse. This part cross-references Dorman OE Solutions 916-946 and Gates VCP804 for the same application.

What It Helps Fix

• Rough idle caused by worn variable valve timing hardware
• Timing noise from excessive lash or tooth wear
• Reduced engine response from inaccurate cam timing
• Emissions concerns related to VVT performance loss
• Loss of drivability on intake right cam timing systems
