• Independent mounting locations for the heat shield, isolating it from mounting bolts to enhance durability
• Machined bolt mating surfaces for a secure, leak-free bolted joint
• Available as a passenger side unit or as a complete kit including both driver and passenger sides
• Includes all necessary hardware such as bolts, nuts, spacers, and gaskets for comprehensive installation
• Designed for precise fitment with specific Dodge, Jeep, and Ram models using VIN decoding for Ram 1500 applications

Construction & Design

This exhaust manifold is crafted from high-silicon ductile iron, a material known for its excellent thermal stability and resistance to deformation under high temperatures. The uniform wall thickness throughout the casting prevents common issues such as warping and cracking that can compromise exhaust integrity.

BD Diesel’s design incorporates extended studs and spacers that accommodate thermal expansion, significantly reducing stress on the fasteners and extending the manifold’s service life. Additionally, the heat shield mounting bosses are independently mounted, separating heat shield stress from the manifold bolts. This thoughtful engineering detail enhances the reliability and longevity of the assembly, ensuring consistent performance under demanding conditions.
