Product Details

Gates Engine Variable Valve Timing Sprocket VCP851 is built as an OE-style cam phaser/cam actuator replacement for engines that rely on precise exhaust cam timing control. The steel construction and OE Exact specification focus on restoring proper valve timing response, which can help return engine operation to factory-like behavior. This part cross-references Hyundai OE number 243703F300 for the same application.

Fits 2009-2012 Hyundai Genesis, exhaust. Fits 2011 Hyundai Equus, exhaust. Fits 2009 Kia Borrego, exhaust. The Gates VCP851 is a direct-fit choice for buyers searching for a Hyundai Genesis exhaust VVT sprocket, Hyundai Equus cam phaser replacement, or Kia Borrego timing chain cam actuator.

Common Repair Symptoms

• Check engine light related to cam timing or VVT performance
• Rough idle or inconsistent engine response
• Reduced fuel economy from incorrect valve timing control
• Loss of power caused by worn or sticking cam phaser components
• Emissions concerns tied to timing control faults

Installation Notes

Verify engine code, exhaust-side application, and timing chain alignment before installation. Replace only with the correct OE-style sprocket for the listed vehicle and position, and follow factory service procedures for cam timing setup, torque values, and synchronization checks. Because this component works within the timing system, accurate indexing and final verification are important after installation.

Quality Assurance

Gates designs this VVT sprocket to OE specifications and uses high-quality materials to support durability and service life. It is tested to help restore engine performance, fuel economy, power delivery, and emissions control when the original cam phaser or actuator has worn or failed.
