Variable valve timing (VVT) sprockets (a.k.a. cam phasers) help maximize engine horsepower and torque curves while reducing emissions and improving vehicle efficiency.
Standard® has designed numerous improvements into our most popular VVT Sprocket for enhanced performance and long-lasting durability. To ensure proper performance, Standard® and Blue Streak® VVT Sprockets are direct-fit OE replacements. They meet tight dimensional tolerances to improve internal sealing, minimize oil drain back and reduce frequency of PCM correction.
Standard®-manufactured VVT Sprockets undergo extensive measurement and life testing, plus a full spectrum of environmental analysis. This regimen includes thermal shock, thermal cycling, salt spray, vibration, storage tests, dirty oil test and more.
