BDD Hardware

Typical aftermarket exhaust manifold bolts are much shorter than stock which after numerous heat cycles can cause them to fatigue and start to stretch, leading to exhaust leaks and possible breakage after repeated re-torques. The finish and coating on most of these bolts can also lead to premature corrosion and zinc embrittlement. Replace damaged or corroded exhaust manifold bolts with BD's class 10.9 bolts and black oxide spacers which improve thermal durability to stand up to the heat and non-Zinc plated fasteners prevent zinc embrittlement. 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. Located in Abbotsford, British Columbia, Canada, BD's state-of-the-art facility covers 65,000 square feet, and employs 60 plus highly-trained individuals. 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.
