Standard Motor Products VVT547 Engine Variable Valve Timing VVT Sprocket

The Standard Motor Products VVT547 is a direct-fit OE replacement engine variable valve timing (VVT) sprocket, also commonly referred to as a cam phaser or camshaft phaser. Engineered to restore proper variable cam timing function, this sprocket is a precision-manufactured component designed to meet or exceed original equipment specifications.

Key Features:

• Direct-fit OE replacement — engineered to match original equipment dimensions and performance characteristics
• All-metal integrated machined design — eliminates paddle inserts for improved wear resistance and more consistent lubrication and gap control
• Tight dimensional tolerances — improves internal sealing, minimizes oil drain-back, and reduces the frequency of PCM correction cycles
• Fast response at lower oil pressure — reduced internal friction allows the sprocket to respond quickly, delivering optimal variable timing performance
• Extensive quality testing — undergoes thermal shock, thermal cycling, salt spray, vibration, storage, and dirty oil testing to ensure long-term durability
• Sold individually

Variable valve timing (VVT), also known as variable cam timing (VCT), plays a critical role in modern engine performance. A failing cam phaser can cause rough idle, poor fuel economy, increased emissions, and stored diagnostic trouble codes. The VVT547 restores accurate camshaft timing control, helping to maximize horsepower and torque output while supporting cleaner, more efficient combustion.
