BD Diesel Exhaust Manifold Kit

2011–2026 Dodge Durango / 2011–2023 Jeep Grand Cherokee / 2019–2024 Ram 1500 5.7L HEMI

Part #: 1041467

Overview

The BD Diesel Exhaust Manifold Kit is a precision-engineered upgrade designed specifically for Dodge Durango, Jeep Grand Cherokee, and Ram 1500 models equipped with the 5.7L HEMI engine. This kit addresses common factory manifold issues such as bolt failures caused by thermal expansion and manifold warping, providing enhanced durability and long-lasting performance under demanding driving conditions.

Ideal for enthusiasts, fleet operators, and professionals seeking a reliable and direct-fit replacement, the BD Diesel manifold kit ensures optimal exhaust flow and maintains structural integrity. It is engineered to improve upon OEM manifolds without sacrificing compatibility or ease of installation.

Key Features

BD Diesel’s Exhaust Manifold Kit incorporates advanced design elements to maximize reliability and performance:

• Constructed from high-silicon ductile iron for superior strength and exceptional resistance to warping and cracking
• Uniform wall thickness throughout the manifold casting to ensure consistent heat distribution and prevent distortion
• Extended fasteners and spacers designed to accommodate thermal expansion, reducing bolt stress and preventing failures
• Independent heat shield mounting locations that isolate heat shield vibrations and stresses from manifold bolts
• Machined bolt mating surfaces for a secure, leak-free bolted joint
• Complete kit includes all necessary gaskets, bolts, nuts, and spacers for a hassle-free installation
• Available as a full kit or as individual left (driver’s side) and right (passenger side) manifolds for selective replacement
• Designed to fit specific VIN configurations for Ram 1500 models from 2019 and newer
• SEMA certified, ensuring quality and performance standards are met

Construction & Design

The BD Diesel Exhaust Manifold Kit is crafted from high-silicon ductile iron, a material chosen for its excellent thermal stability and durability under extreme heat cycles. This construction minimizes the risk of warping and cracking that commonly affect stock manifolds over time. The uniform wall thickness throughout the manifold casting promotes even heat distribution, reducing stress points and extending the component’s lifespan.

Innovative engineering features such as extended studs and spacers allow the manifold to expand and contract with heat without compromising fastener integrity. Additionally, the heat shield mounting bosses are independently mounted, isolating heat shield vibrations and stresses from the manifold bolts. This design significantly enhances the manifold’s durability and reliability in high-temperature environments.

Installation & Fitment

This exhaust manifold kit is designed for direct bolt-on installation on select Dodge Durango (2011–2026), Jeep Grand Cherokee (2011–2023), and Ram 1500 (2019–2024) models equipped with the 5.7L HEMI engine. The kit includes all necessary hardware—gaskets, bolts, nuts, and spacers—to ensure a straightforward installation without the need for additional modifications.

For Ram 1500 models from 2019 and newer, proper VIN decoding is recommended to confirm compatibility, specifically verifying the 6th digit of the VIN for model designation. Note that this kit is not compatible with 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.

What's Included

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