The Cummins Engine: A Tradition of Legendary Power

The history of Cummins, Inc. is a story of American ingenuity meeting the greater public’s needs. Clessie Cummins — a farm boy from rural Indiana with no formal education past the eighth grade —made the first Diesel-powered automobile out of a Limousine, and within only three years, his engine would power a car that completed more than 13,000 miles at Indianapolis' motor speedway.
Then, in post-WWII America, the Cummins N Series engine would go on to power over half of the heavy-duty trucks used in the U.S. building boom between 1952 and 1959. By 2013, the company had established operations in nearly 200 countries and territories worldwide.
Today, Cummins engines can be found powering practically every category of vehicle, from heavy-duty 18-wheelers and construction equipment to pickup trucks and even commercial Cummins marine diesel parts.

Cummins Engine Parts for Sale for Both Newer and Older Engines

We are focused on stocking Cummins parts online for a wide selection of engine types. We carry Cummins 4BT parts, with everything from pumps to rebuild kits, to gaskets and much more.

Looking for an older engine? With some Cummins engines logging over 1 million miles, it's no wonder that many of these engines are still running today. However, the key to longevity is proper care, maintenance and especially parts. These include the N14, which was gradually phased out and replaced with the Cummins ISX and QSX models. We also have parts for the Cummins L10 and its later incarnation, the M11.
