The BD Diesel Exhaust Manifold Bolt & Spacer Kit (engineered for Ford F250/F350 6.0L Power Stroke models from 2003-2007) offers enhanced thermal durability and prevents zinc embrittlement. Typical aftermarket exhaust manifold bolts often fall short of the factory specifications, leading to potential issues after repeated exposure to high temperatures. These shorter bolts can experience fatigue and stretching over time, resulting in exhaust leaks and an increased risk of breakage, particularly after multiple re-torquing attempts. Furthermore, the surface treatments commonly found on these bolts can be susceptible to premature corrosion and zinc embrittlement.
To address these concerns, BD Diesel has developed a robust solution. This kit includes class 10.9 bolts and precisely engineered spacers, designed to improve the overall thermal durability of the exhaust manifold fastening system. The use of non-zinc plated fasteners eliminates the risk of zinc embrittlement, ensuring long-lasting performance.
