BD Diesel Performance is unique among its peers in that it designs, manufactures and distributes a wide range of products specifically engineered for performance diesel applications. The BD name became recognized in 1989, when the company introduced the first exhaust brake for the burgeoning diesel pick-up truck market. BD's roots, however, actually date back to 1972, when Valley Fuel Injection, Ltd. first opened its doors. Today, Valley Fuel Injection and BD Diesel Performance are one, with eight specialty divisions that focus on diesel power train components: Fuel Injection Calibration Department, Exhaust Brake Manufacturing, Electronic Circuit Design and Assembly, Transmission and Torque Converter Design and Remanufacturing, Turbocharger Design, Installation and Research and Development.
