Valve timing determines when and how long the intake and exhaust valves open and close. This technology helps to provide smoother idling and is used to improve fuel economy, emisions and vehicle performance. Our VVT sprockets are precision machined to ensure accurate variable valve timing, correct rough idle and restored drivability. Each of our VVT sprockets help to restore and maximize engine horsepower and torque curves while reducing emissions and improve vehicle efficiency by controlling when the intake and exhaust valves open and close. Our sprockets are designed to have low leakage and lash which offers improved performance and noise free operation. Each of our VVT sprockets undergo 100% end of line testing to ensure that quality meets or exceeds OE specifications.
