BD Diesel Exhaust Manifold Kit

Fits 2013–2018 RAM 3500, 4500, and 5500 with 6.7L Cummins Engine Cab & Chassis

Part #: 1046068

Overview

This BD Diesel Exhaust Manifold Kit is engineered specifically for 2013 to 2018 RAM 3500, 4500, and 5500 Cab & Chassis models equipped with the 6.7L Cummins engine. Designed as a fully divided pulse manifold, it supports efficient exhaust flow and thermal management under demanding conditions. Ideal for owners seeking a durable replacement or upgrade, this kit enhances manifold longevity and reliability by addressing common issues related to heat and vibration.

Constructed to endure extreme temperatures and engine vibrations, this manifold kit helps maintain consistent exhaust performance while reducing the risk of thermal fatigue. It is a practical choice for those who prioritize long-term durability and ease of maintenance in their diesel truck’s exhaust system.

Key Features

Key features of this exhaust manifold kit include:

• Made from high-silicon ductile iron for superior heat resistance and durability
• Fully divided pulse design to optimize exhaust gas flow and reduce backpressure
• Precision slip joints that accommodate thermal expansion and contraction, minimizing cyclic fatigue
• Includes new gaskets, bolts, and spacers for a complete and convenient installation
• Engineered specifically for 6.7L Cummins engines in RAM 3500, 4500, and 5500 Cab & Chassis trucks
• Designed to withstand harsh operating environments typical of heavy-duty diesel applications

Construction & Design

The manifold’s high-silicon ductile iron construction provides exceptional resistance to cracking and warping caused by high exhaust temperatures and vibration. The fully divided pulse design helps maintain exhaust pulse timing, which can contribute to smoother engine operation and reduced stress on exhaust components. Precision slip joints allow the manifold to flex with thermal cycles, significantly extending the service life compared to rigid designs.

Installation & Fitment

This kit is designed as a direct fit replacement for the specified RAM Cab & Chassis models with the 6.7L Cummins engine, simplifying installation. The inclusion of all necessary gaskets, bolts, and spacers ensures you have everything needed for a secure and proper fit, reducing downtime and installation complexity.
