Variable valve timing sprockets (a.k.a. cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency. To ensure proper performance for this important category, NAPA® Echlin® VVT sprockets meet tight dimensional tolerances to improve internal sealing, minimize oil drain back, and reduce frequency of PCM correction.
Our all-metal, integrated machined design eliminates paddle inserts while providing a larger contact area. This means improved overall wear as well as proper lubrication and gap. Less friction means our sprocket responds fast at lower pressure, delivering optimal performance.
Better performance in timing-phase response, oil loss and working life of locking pin and overall component
Better match and correct tolerance
No friction between sprocket and rotor
New re-designed coil spring
OE-style installation bolts included with sprocket for ease of installation
