Big Bear Engine Company

WHO WE ARE Big Bear Engine Company - Experience The Power of Diesel Big Bear Engine Company was originally founded as a division of a larger diesel engine remanufacturing company in Denver, Colorado. As the company grew the demand for smaller industrial Caterpillar and Cummins crate diesel engines became apparent and Big Bear Engine Company spun off on its own. Today the two companies still work side by side and are located in the same engine manufacturing complex. Today we specialize in engine 3 models: Cummins 4BT Engine, Cummins 6BT Engine and the Caterpillar 3306 Engines. Our talents lie within the finite science of engineering and manufacturing of diesel engines.
