Insist on Genuine STAMFORD, AvK and MARKON Parts

Appearances can be deceiving. This is especially true when it comes to critical parts for your ac generator. AVRs, for example. In some ways, one AVR might look much the same as another. Yet closer inspection will reveal that there are dramatic differences between Genuine STAMFORD, AvK and MARKON parts and others. Differences in design, tolerances and materials. The truth is, Genuine Parts deliver improved performance and longer life between overhauls. It's that simple.

Every Part. Genuine.

Cummins Generator Technologies continually improves the performance characteristics of its ac generators through its ongoing investment in research and development. And, as improvements are made, they are incorporated into Genuine STAMFORD, AvK and MARKON parts.

Genuine STAMFORD, AvK and MARKON Parts:

  • Meet exacting Cummins Generator Technologies specifications
  • Utilize advanced materials
  • Incorporate state-of-the-art Cummins Generator Technologies design technology
  • Are continually improved
  • Have an industry-leading warranty
  • Are backed by a global service organization

Every Part. Proven.

STAMFORD, AvK and MARKON parts undergo countless hours in the test cell, plus millions of hours in field testing to ensure reliability and durability. Genuine STAMFORD, AvK and MARKON parts are proven. Others aren't.

Even though a non-genuine part might fit your alternator, there is no guarantee it will perform. Others try to copy STAMFORD, AvK and MARKON components without knowing the design and materials specifications that are critical to performance. Installing non-genuine parts may cause early failure which can result in unscheduled downtime and increased repair costs. Play it safe and smart - purchase your replacement parts from an authorized Cummins Generator Technologies distributor or dealer.
