2017 Ford Expedition Timing Cam Gears

The variable valve timing sprocket is key to ensuring an engine’s performance and clean running. Replace a worn factory VVT sprocket with this quality engineered sprocket to restore lost performance. Designed to install and perform like the original.

The variable valve timing (VVT) system allows the engine control module (ECM) to regulate the intake and exhaust valve phase angle providing the most optimal engine volumetric efficiency under all engine operating condition to control tailpipe emissions and engine efficiency. Variable valve timing is an emission control device and although there are various methods of operation, the typical device is regulated by oil control valves, actuator solenoids and camshaft phasers.

Variable Valve Timing (VVT) Sprockets, also known as camshaft phasers, offer technicians a repair solution for higher mileage vehicles and include all necessary components for a complete repair. Designed and manufactured using premium materials. 100% tested and measured for function, fitment, and durability to ensure optimal performance. Test parameters include adjustable angle, leakage, locking pin functionality and friction. Includes new camshaft phaser torque-to-yield (TTY) attachment bolts including valving bolts to ensure proper installation and phaser function. Cloyes recommends replacing the timing chain, tensioners, sprockets, and guides alongside VVT components to maintain system stability and ensure precise engine timing. Trusted by professionals for over a century and backed by an industry-leading warranty and technical support.

Optimal long-term performance of a variable valve timing (VVT) system requires a reliable and rugged cam phaser, also known as a timing sprocket. The factory phasers on certain Ford and Lincoln trucks and SUVs with a 3.5L V6 Eco Boost engine can fail prematurely from excessive internal wear. This Dorman OE FIX exhaust cam phaser features significant upgrades to the original equipment design to provide longer service life and better performance than the OEM replacement. A two-step locking pin and deeper receiving seat replace the factory sprocket’s straight pin design, providing more secure engagement and stability during phaser actuations that eliminates the rattling sound typical of a malfunctioning sprocket. This cam phaser also has an innovative oil wiper designed with concave sealing edges, an upgrade from the factory’s flat wiper profile. The unique surface geometry seals oil much more effectively, enabling faster actuations of the cam to advance and retard positions and extending wiper life by reducing surface wear. The durability of this upgraded cam phaser has been proven far beyond the limits of many aftermarket competitors’ on-vehicle tests. Our custom-built VVT cam phaser testing apparatus simulates 50,000 miles of real-world driving in just four weeks, promising a highly-engineered and upgraded replacement part that offers a better and longer-lasting repair. A special service tool is included for a hassle-free installation.
