Product Details

The Gates Engine Variable Valve Timing Sprocket, part number VCP808, is an OE-performance cam phaser/cam actuator component engineered for precise timing control. Gates builds this sprocket to match original equipment specifications so it installs with the correct fit and operates as intended in the engine’s variable valve timing system. The steel housing and OE Exact rating support consistent operation in demanding engine environments. This part cross-references Dorman - OE Solutions 917-253 for the same application.

Compatible With 2010-2013 Mazda 3, N/A. Compatible With 2007-2011 Mazda CX-7, N/A. If you are replacing a worn Mazda 3 VVT sprocket or servicing a Mazda CX-7 cam actuator, VCP808 is the direct-fit part number to verify against your original component.

Common Problems This Part Can Address

• Erratic cam timing from a worn variable valve timing sprocket
• Check engine light concerns related to VVT operation
• Reduced engine response caused by timing control issues
• Rough running from a failing cam phaser or actuator
• Loss of fuel economy tied to improper valve timing

Installation Notes and Tips

Confirm the original sprocket tooth count, chain row configuration, and overall dimensions before installation. This part uses a timing chain drive and does not include mounting hardware. Because VVT components are timing-critical, installation should be performed with the engine properly timed and all related components inspected for wear.

Quality Assurance

Gates designs this VVT sprocket to OE specifications and tests it to help restore engine performance, fuel economy, power delivery, and emissions control. The VCP808 is built as an OE-style replacement for Mazda applications requiring precise variable valve timing operation.
