Standard Motor Products VVT540 Engine Variable Valve Timing VVT Sprocket

The Standard Motor Products VVT540 is a premium direct-fit replacement Variable Valve Timing (VVT) sprocket, also commonly referred to as a cam phaser. Designed as a new-production component with no remanufactured parts, it restores proper camshaft timing control to maintain engine performance, fuel efficiency, and emissions compliance.

Key Features:

• Direct-fit OE replacement engineered to match original equipment dimensions and performance
• All-metal, integrated machined design eliminates paddle inserts for improved wear resistance and a larger internal contact area
• Tight dimensional tolerances improve internal sealing, minimize oil drain-back, and reduce frequency of PCM correction
• 100% new construction — contains no remanufactured components
• Extensive validation testing including thermal shock, thermal cycling, salt spray, vibration, storage, and dirty oil testing
• Precision-machined for accurate variable valve timing to correct rough idle and restore drivability
• Reduces friction for fast response at lower oil pressure, delivering optimal performance

Variable Valve Timing (VVT) sprockets are a critical engine component responsible for maximizing horsepower and torque curves while reducing emissions and improving overall vehicle efficiency. A worn or failed VVT sprocket can trigger diagnostic trouble codes, cause rough idle, stalling, and poor engine performance. The Standard Motor Products VVT540 is manufactured to meet the rigorous demands of modern VVT systems and is backed by Standard's comprehensive aftermarket warranty.
