Detailed Description

The Dorman 916-539 variable valve timing sprocket is built to replace a worn factory sprocket that can affect engine performance and smooth running. By restoring the timing relationship on the exhaust side, this VVT sprocket helps maintain the engine’s intended operation in vehicles such as the Dodge Journey, Jeep Compass, and Jeep Patriot. The steel construction and OE-style fitment support direct replacement service for common 2.0L and 2.4L engine applications where this design is specified.

This part cross-references Standard Ignition VVT558 for the same application.

What It Helps Address

• Rough idle caused by worn VVT sprocket components
• Loss of engine response from incorrect valve timing
• Check engine light conditions related to timing performance
• Noise or irregular operation from a deteriorated sprocket
• Reduced drivability in exhaust-side VVT systems

Installation Notes and Tips

Install the sprocket on the exhaust side only where specified by the vehicle application. Verify timing marks, chain alignment, and camshaft position before reassembly. Because this is a bolt-on replacement part, proper torque procedures and service manual steps should be followed during installation. Confirm fitment by year, make, model, and engine configuration before ordering.

Quality Assurance

Dorman designs this replacement sprocket to match original fit and function for the listed applications. The part is built as a standard replacement component for service on Chrysler, Dodge, and Jeep engines that require an exhaust VVT sprocket.
