Gates VCP841 Engine Variable Valve Timing (VVT) Sprocket

OE-Style VVT Sprocket for Hyundai and Kia

The Gates VCP841 is an engine variable valve timing sprocket built to OE performance standards for fit, form, and function. It is designed for 2006-2011 Hyundai Accent, 2006-2011 Kia Rio, and 2006-2011 Kia Rio5 applications with interference engines, where accurate cam timing is critical to engine operation.

Key Features

• OE performance Variable Valve Timing sprocket, also referred to as a cam phaser or cam actuator
• Built from aluminum and steel for durability and service life
• Timing chain drive with 25 teeth and .148 in tooth thickness
• Overall diameter: 3.5 in; overall height: 2.05 in
• Single-row chain design with one mounting hole and no mounting bolt provision
• Engineered to restore proper valve timing response, fuel economy, power delivery, and emissions control

Detailed Description

Gates Engine Variable Valve Timing Sprocket VCP841 is manufactured to OE specifications to match the original fit, form, and performance expected in modern timing systems. The housing uses aluminum and steel construction, and the timing chain drive layout is designed for precise camshaft control in the engine’s variable valve timing system. This part cross-references Standard Ignition VVT638 for the same application. For drivers servicing a Hyundai Accent, Kia Rio, or Kia Rio5, VCP841 provides a direct replacement solution for restoring timing system operation.

What It Helps Address

• Rough engine performance caused by worn or inaccurate cam timing
• Reduced fuel economy related to variable valve timing issues
• Loss of power from delayed or inconsistent cam phasing
• Increased emissions from timing control problems
• Timing system noise or drivability concerns tied to a failing VVT sprocket

Installation Notes and Tips

Verify engine code and timing chain alignment before installation, especially on interference-engine applications. Confirm the sprocket matches the original tooth count, diameter, and chain-row configuration before assembly. Follow factory service procedures for cam timing setup, torque values, and final synchronization after replacement. Fits 2006-2011 Hyundai Accent, N/A. Fits 2006-2011 Kia Rio, N/A. Fits 2006-2011 Kia Rio5, N/A.

Quality Assurance

Gates designs this VVT sprocket to OE performance standards and tests it to help restore engine performance, fuel economy, power output, and emissions control. The VCP841 is built for long service life using durable materials selected for timing system demands.
