Notable for its high-quality products and forward-thinking design, Moog has become a trusted brand in the global automotive industry.

During the 1930s, the Moog brothers decided to start manufacturing front-end parts.

In 1937, technicians found out that the replacement parts manufactured by Moog outperformed the original factory components.

The innovation they brought to the design and manufacturing of these components helped them earn the “Problem Solver” status they’re known for to this day.

Moog continued to innovate in the following years, which helped them build a long-standing NASCAR relationship. The company currently holds more than 50 patents.

Moog has long been a leading expert in the automotive industry in the US but launched its operations in Europe in 2001.

The company has earned a phenomenal reputation in Europe, as well as other parts of the world.
