INA VV-VC107 Variable Valve Timing VVT Sprocket Camshaft Phaser

The INA VV-VC107 is a precision-engineered Variable Valve Timing (VVT) sprocket, also known as a VCT camshaft phaser, designed to optimize engine performance and efficiency. This critical valve train component adjusts camshaft timing by rotating the camshaft position relative to the crankshaft, allowing the engine management system to optimize valve timing under varying operating conditions.

Key Features:

• Hydraulically-actuated camshaft phaser for precise valve timing control
• Steel construction for durability and long service life
• Meets or exceeds OEM performance specifications
• Direct replacement for GM OEM part numbers 12621505 and 12578516
• Interchanges with Cloyes VC107 and Gates VCP800
• Pre-loaded and properly positioned for immediate installation

This VVT sprocket improves engine efficiency, reduces fuel consumption, and lowers exhaust emissions by allowing the engine control module to advance or retard camshaft timing based on engine speed, load, and operating conditions. The precision-machined design ensures quiet operation and maintenance-free performance when installed with clean engine oil at the proper viscosity.
