OE Performance VVT Sprocket

Gates VCP977 is an OE performance engine variable valve timing sprocket for the exhaust right side. It is built to OE specifications for fit, form, and performance, making it a direct replacement for Mercedes-Benz applications that rely on precise cam timing control.

• OE performance variable valve timing sprocket for timing chain drive systems
• Steel construction for durability and service life
• 33-tooth design with a single chain row
• Engineered to restore engine performance, fuel economy, power, and emissions control
• Fits Mercedes-Benz models including E350, C350, and GLE350 applications

Detailed Fitment and Function

This Gates VVT sprocket, part number VCP977, is commonly referred to as a cam phaser or cam actuator. It is designed for Mercedes-Benz engines that use exhaust-side variable valve timing to manage cam timing under changing load and speed conditions. Compatible applications include 2012-2020 Mercedes-Benz S450, 2013-2018 Mercedes-Benz E400, and 2016-2018 Mercedes-Benz GLE350, along with additional Mercedes-Benz fitments listed for the exhaust right position. The part number VCP977 is also cross-referenced to URO 2760503900 for the same application.

Gates’ Engine Variable Valve Timing Sprocket line focuses on OE-style replacement parts built around factory specifications. For buyers replacing a worn or noisy cam timing component, this line emphasizes correct fitment, stable timing operation, and consistent engine response across supported Mercedes-Benz models.

Common Issues This Part Can Address

• Rattling or ticking from the cam timing area
• Cam timing faults that trigger engine warning lights
• Reduced power caused by unstable valve timing
• Poor fuel economy linked to timing control issues
• Higher emissions from incorrect cam phasing

Installation Notes

Verify engine code, exhaust-side application, and model-year coverage before installation. This sprocket uses a timing chain drive and has one mounting hole with no mounting bolts specified in the product data. Mounting hardware is not included. Because variable valve timing components affect engine synchronization, installation should follow factory service procedures and timing marks exactly.

Quality Assurance

Gates tests these OE performance sprockets to help restore engine performance, fuel economy, power, and emissions control. The steel construction and OE-spec design support durability and maximum service life in Mercedes-Benz engine applications.
