Dorman 916-777 Exhaust Camshaft Phaser Variable Timing VVT Sprocket

The Dorman 916-777 is an OE FIX exhaust camshaft phaser engineered with significant upgrades over the original equipment design to provide longer service life and better performance for Ford and Lincoln vehicles equipped with 3.5L V6 EcoBoost engines. This part addresses the premature failure issue common with factory phasers that occurs due to excessive internal wear.

Key Design Improvements:

• Two-step locking pin with deeper receiving seat replaces the factory sprocket's straight pin design, providing more secure engagement and stability during phaser actuations that eliminates rattling sounds
• Innovative oil wiper designed with concave sealing edges, upgrading from the factory's flat wiper profile
• Unique surface geometry seals oil more effectively, enabling faster actuations to advance and retard positions

Quality Testing:

Dorman's custom-built VVT cam phaser testing apparatus simulates 50,000 miles of real-world driving in just four weeks, ensuring this upgraded replacement part delivers a better and longer-lasting repair. A special service tool is included for hassle-free installation.

This camshaft phaser is also known as a variable valve timing (VVT) sprocket or timing sprocket and is an essential component for optimal long-term performance of the engine's variable valve timing system.
