Who is Industrial Injection?

Industrial Injection is a family-operated business that the late Brady Williams founded in 1985. He started having an interest in the business when he was young and mopped floors in a local shop every after school.

From then on, his interest in engines increased. He became a Diesel specialist for all turbo and fuel equipment manufacturers. After years of hard work and sacrifices, Brady then opened Industrial Injection at the age of 30.

The Turning Point

Initially, Industrial Injection catered to industries such as construction, agricultural, and mining equipment. He was also catering to some road truck engines but not that much.

It was not until major automotive companies such as Ford, Dodge, and GM decided to use diesel engines for their pickup trucks that Industrial Injection decided to change its focus market.

The company has become one of the leading companies that supply and remanufacture diesel fuel systems, engines, and turbochargers. Even after all those years, they still have not forgotten their roots as it still caters to the industries it initially serviced.

For more than 35 years, the company has consistently provided quality diesel products that many enthusiasts enjoy.
