Standard Motor Products VVT550 Engine Variable Valve Timing VVT Sprocket

The Standard Motor Products VVT550 is a direct-fit OE replacement engine variable valve timing (VVT) sprocket, also commonly referred to as a cam phaser. Designed to restore accurate variable valve timing, this sprocket helps maximize engine horsepower and torque curves while reducing emissions and improving overall vehicle efficiency.

Key Features:

• Direct-fit OE replacement — engineered to match original equipment dimensions and performance specifications
• Precision-machined construction — ensures accurate variable valve timing, corrects rough idle, and restores drivability
• All-metal integrated machined design — eliminates paddle inserts while providing a larger contact area for improved wear and proper lubrication
• OE-matching sprocket tooth profiles — deliver quiet, smooth operation
• Tight dimensional tolerances — improve internal sealing, minimize oil drain-back, and reduce frequency of PCM correction
• 100% new components — contains no remanufactured parts
• Extensive quality testing — undergoes thermal shock, thermal cycling, salt spray, vibration, storage, and dirty oil testing for long-lasting durability

Standard Motor Products VVT sprockets are engineered to lower leakage and lash for noise-free, high-performance operation. The reduced friction design allows the sprocket to respond quickly at lower oil pressure, delivering optimal cam phasing performance. When replacing VVT components, it is recommended to inspect and replace related timing chain components and VVT solenoids as a complete system service.
