BD Diesel

BD Diesel has been engineering performance solutions for trucks and heavy-duty applications since 1987, building a reputation for tackling the weak points in factory powertrains and exhaust systems. At Stateside Performance, we stock BD Diesel parts designed to deliver real-world durability and improved performance for daily drivers, tow rigs, and work trucks alike. Our current BD Diesel lineup focuses on 5.7L Hemi exhaust manifold kits, a critical upgrade for owners battling cracked or warped factory manifolds, broken studs, and exhaust leaks that rob power and create that all-too-familiar tick at startup. These heavy-duty replacements are engineered to outlast the OEM units, restoring proper exhaust flow and sealing for years of reliable service. While our BD Diesel exhaust manifold offerings are tailored specifically for Ram 1500, 2500, and 3500 trucks equipped with the 5.7L Hemi across a wide range of model years, Stateside Performance carries a full catalog of aftermarket parts and accessories with fitments for Ford, Chevy, GMC, Ram, Dodge, Jeep, and Cadillac trucks and SUVs. Whether you're refreshing a high-mileage Hemi or proactively upgrading before the factory manifolds fail, BD Diesel components give you confidence that the repair will hold up to whatever you throw at it. Every product ships with the quality and engineering BD Diesel is known for, backed by Stateside Performance's commitment to fast shipping and straightforward customer support.
