Overview:

The BD Diesel Exhaust Manifold Kit is engineered specifically for Dodge Durango, Jeep Grand Cherokee, and Ram 1500 models equipped with the 5.7L HEMI engine. Designed to deliver enhanced durability and long-lasting performance, this exhaust manifold kit addresses common issues such as bolt failures caused by thermal expansion. Ideal for enthusiasts and professionals seeking a reliable upgrade, the BD Diesel manifold kit ensures your vehicle maintains optimal exhaust flow and structural integrity under demanding conditions.

With a focus on durability and fitment precision, this kit is a direct replacement that improves upon factory manifolds by incorporating advanced design features to reduce stress and prevent warping. It is perfect for those looking to maintain or improve their vehicle’s exhaust system reliability without compromising OEM compatibility.

Key Features:

BD Diesel’s Exhaust Manifold Kit offers a range of technical enhancements designed to improve reliability and performance:

• Constructed from high-silicon ductile iron for superior strength and resistance to warping
• Uniform wall thickness throughout the manifold to prevent cracking and distortion
• Extended fasteners and spacers to effectively manage thermal expansion and reduce bolt stress
• Independent heat shield mounting locations to isolate heat shield stress from mounting bolts
• Machined bolt mating surfaces for a secure, leak-free bolted joint
• Includes all necessary gaskets, bolts, nuts, and spacers for complete installation
• Available as a full kit or as left (driver’s side) and right (passenger side) manifolds separately
• Designed to fit specific VIN configurations for Ram 1500 models (2019 and newer)
• SEMA certified for quality and performance assurance

Construction & Design:

The BD Diesel Exhaust Manifold Kit is precision-crafted from high-silicon ductile iron, a material known for its excellent thermal stability and resistance to warping under extreme heat cycles. The uniform wall thickness throughout the manifold casting ensures consistent heat distribution, minimizing the risk of cracks or deformation over time. This robust construction extends the life of the manifold, making it a dependable upgrade over stock components.

Innovative engineering includes extended studs and spacers that accommodate thermal expansion, reducing stress on fasteners and preventing common bolt failures. The heat shield mounting bosses are independently mounted, isolating heat shield vibrations and stresses from the manifold bolts, further enhancing durability and reliability.

Installation & Fitment:

This exhaust manifold kit is designed for direct bolt-on installation on select Dodge Durango, Jeep Grand Cherokee, and Ram 1500 models equipped with the 5.7L HEMI engine. The kit includes all necessary hardware—gaskets, bolts, nuts, and spacers—to facilitate a straightforward installation without the need for additional modifications. Proper VIN decoding is recommended for Ram 1500 models (2019+) to ensure compatibility, specifically checking the 6th digit of the VIN for model designation.

Note that this kit does not fit 2019 or later DS body style vehicles. For applications requiring only one side, left (driver’s side) and right (passenger side) manifolds are available separately under part numbers 1041465 and 1041469 respectively.

What's Included:

• Left and right exhaust manifolds (full kit)
• All new bolts, nuts, and spacers
• High-quality gaskets for a secure seal
• Installation hardware for heat shield mounting
• Detailed fitment guide and VIN decoder information for Ram 1500

Ideal For:

This BD Diesel Exhaust Manifold Kit is ideal for Dodge, Jeep, and Ram owners who demand enhanced durability and reliability from their exhaust system components. It suits daily drivers, fleet vehicles, and performance enthusiasts who want to prevent common exhaust manifold failures and maintain peak engine performance. It is also a smart choice for those performing maintenance or upgrades on 5.7L HEMI-powered trucks and SUVs from 2011 through 2024.

BD Diesel Performance designs and manufactures diesel performance parts aimed at stronger power delivery, improved reliability, and heavy-duty capability. Their lineup spans turbo and fueling upgrades, manifolds, intercoolers, and other supporting components—built for Cummins, Power Stroke, and Duramax owners who want more torque for towing, work, or competition.
