Cloyes (9-0391SBVVT): Variable Valve Timing (VVT) Chain Kit for Ford 4.6L/5.4L

Cloyes’ Variable Valve Timing (VVT) Chain Kits and Components offer technicians a complete repair solution for higher mileage vehicles and are designed for the replacement of worn or damaged timing chains, tensioners, sprockets, guides, and VVT actuators (also known as cam phasers). Cloyes parts are CAD designed and manufactured using premium materials. VVT components are 100% tested during production. Each part is extensively tested and measured for function, fitment, and durability to ensure optimal performance. Test parameters include adjustable angle, leakage, locking pin functionality, friction, max oil flow, and holding duty cycle. VVT Chain Kits include new camshaft phaser torque-to-yield (TTY) attachment bolts to ensure proper installation and phaser function

For the popular 3V Ford 4.6-liter and 5.4- liter applications, Cloyes has developed a uniquely designed actuator that is superior to the OE and competitive aftermarket product, performing better under low oil pressure conditions by eliminating contact between rotor and stator resulting in 10% more torque and 20% less internal drag.
