Management Team

JVS has a long and successful history of providing the highest level of Quality, Delivery, Service and overall Value to our customers, globally, for the past 52 years. As a tribute to our longevity, JVS reached another milestone this year with the production of our 5 Millionth engine brake.

During this time we have developed unique processes in hydraulics, precision machining, motion, valve timing and electronics applied to engines and vehicles.  The foundation of our success is based on four Core Values that drive our business today and will continue into the future…

  • Build the Best Team
  • Continuous Improvement (Kaizen)
  • Creating An Environment That Rewards Innovation and Creativity
  • Providing Returns To Our Stakeholders That Outperform Relative to Our Competitors

As we continue our journey, increased demand for our products and technologies is coming from new geographies requiring us to evolve our portfolio and customer services to meet the high level of expectation from these markets.

We are excited to announce a new initiative at JVS which was developed to highlight our competencies and capabilities that have helped to drive our success over the years.  The result was JVS Engineering.  This is a group inside JVS that takes on engineering challenges not necessarily related to engine braking and is a means of starting conversations that will lead to relevant technology and manufacturing programs.  Take a moment to see what JVS Engineering is all about.

Our brand and reputation are important to us, so you can count on JVS to provide solutions based on proven technologies and demonstrated reliability.  We also strive to be good citizens and neighbors, so we develop our products and processes with consideration given to their impact on the environment and those we share it with.

On behalf of all of us at Jacobs, thank you for your support and interest in our company and our products.  Don’t hesitate to contact us in any way if we can be of assistance.

Sincerely,
Sergio Sgarbi, President 
Jacobs Vehicle Systems
