Mishimoto Exhaust Manifold Stud Kit

1994–2018 Dodge Ram 1500, 2500, 3500 5.9L & 6.7L Cummins Diesel

Part #: MMEXH-RAM-94SK

Overview

The Mishimoto Exhaust Manifold Stud Kit is a precision-engineered solution designed specifically for Dodge Ram trucks equipped with 5.9L and 6.7L Cummins diesel engines from 1994 through 2018. This stud kit replaces the factory bolts to provide a stronger, more reliable connection between the exhaust manifold and cylinder head. By increasing clamping force, it helps prevent boost leaks and manifold warpage, common issues that can compromise engine performance and durability under high-boost conditions.

Ideal for Cummins diesel enthusiasts, professional mechanics, and anyone upgrading or maintaining their exhaust and turbo systems, this kit simplifies installation and ensures a secure, leak-free seal. Its robust design and lifetime warranty offer long-term peace of mind for critical engine components.

Key Features

Engineered to meet the rigorous demands of high-performance diesel applications, the Mishimoto Exhaust Manifold Stud Kit delivers several important benefits:

• Increases clamping force between the exhaust manifold and cylinder head to reduce boost-killing leaks
• Constructed from chromium-infused steel for superior strength and corrosion resistance
• Minimizes the risk of manifold warpage caused by uneven or insufficient clamping
• 12-point hardware design prevents nut rounding and stripping during installation or removal
• Facilitates easier and more accurate alignment of exhaust manifold and turbocharger components
• Compatible with a wide range of Dodge Ram 1500, 2500, and 3500 models from 1994 to 2018
• Backed by Mishimoto’s Lifetime Warranty for durability and reliability

Construction & Design

The stud kit is crafted from high-quality chromium-infused steel, providing exceptional tensile strength and outstanding resistance to rust and corrosion. These properties are essential for exhaust system components exposed to extreme heat and harsh environmental conditions. The 12-point nuts included in the kit are designed to distribute torque evenly, preventing rounding or stripping and ensuring a secure, long-lasting fit.

This precision engineering maintains the integrity of the exhaust manifold connection, reducing the likelihood of leaks and component failure even under demanding boost pressures and thermal cycles.

Installation & Fitment

Installation is straightforward for anyone experienced with exhaust system work. The kit replaces the factory manifold bolts with studs and 12-point nuts, making it easier to align the heavy exhaust manifold and turbocharger during assembly. This reduces installation frustration and improves accuracy, especially in tight engine bays.
