About GP Sorensen® VVT

The Aftermarket's Broadest VVT Coverage

Variable valve timing systems are designed to reduce emissions and maximize engine performance and fuel economy. The electro-mechanical system depends on the circulation of engine oil. Lack of oil circulation can cause VVT components to fail prematurely.

With over 525 SKUs and counting, including more than 100 exclusive units, we offer the most comprehensive Variable Valve Timing program in the aftermarket. We're determined to continue broadening our VVT program with increased coverage and expanded manufacturing at our certified facility in Bialystok, Poland.
