PPE Exhaust Manifold Bolt and Spacer Kit: Dodge Ram (98-18)

PPE Exhaust Manifold Bolt and Spacer Kit

1998–2018 Dodge Ram 5.9L/6.7L Cummins

216110100

Overview:

The PPE Exhaust Manifold Bolt and Spacer Kit is a precision-engineered replacement set designed specifically for Dodge Ram trucks equipped with 5.9L and 6.7L Cummins engines from 1998.5 through 2018. Over time, factory exhaust manifold bolts can suffer from heat-induced fatigue, stretching, and corrosion, leading to exhaust leaks that affect engine performance and reliability. This kit offers a durable, high-quality solution to restore proper sealing and maintain the integrity of your exhaust system.

Ideal for owners looking to upgrade worn or rusted manifold bolts, this kit ensures a long-lasting fitment that withstands the extreme thermal cycles typical of diesel exhaust systems. By addressing common failure points, it helps prevent exhaust leaks and the associated noise, emissions, and potential engine damage.

Key Features:

Engineered for durability and precision, the PPE Exhaust Manifold Bolt and Spacer Kit includes components designed to improve longevity and performance under harsh conditions:

• Includes 12 flange head exhaust bolts (M10x1.5-60mm) made from Grade 10.9 steel for superior strength
• 12 precision-machined spacers to reduce bolt stress caused by heat expansion
• 2 stainless steel socket bolts (M10x1.5-35mm) and 2 stainless steel M10 washers for secure fastening
• Centerless ground and rolled bolts to minimize stress concentrations and enhance fatigue resistance
• Black oxide finish on all fasteners for corrosion resistance and a professional appearance
• Designed to mitigate heat-induced bolt stretching and prevent permanent yield
• Compatible with 2003–2007 5.9L Cummins models (requires removal of factory heat shield)
• Fits 1994–1998 5.9L Cummins with aftermarket manifolds (not compatible with OEM manifolds)

Construction & Design:

The bolts in this kit are manufactured from high-grade steel with a Grade 10.9 rating, ensuring exceptional tensile strength and durability under the extreme heat cycles of diesel exhaust systems. Each bolt undergoes centerless grinding and rolling processes to reduce stress risers, which are common failure points in factory hardware. This meticulous manufacturing process extends the service life of the bolts and helps maintain a tight exhaust seal.

Spacers included in the kit serve a critical function by compensating for thermal expansion differences between the manifold and bolts, reducing the risk of bolt deformation or breakage. The black oxide finish provides a protective barrier against rust and corrosion, preserving the integrity of the fasteners even in harsh under-hood environments.

Installation & Fitment:

Installation of the PPE Exhaust Manifold Bolt and Spacer Kit is straightforward for experienced mechanics and enthusiasts familiar with Cummins diesel engines. The kit is designed to directly replace factory manifold bolts on 1998.5–2018 Dodge Ram trucks with 5.9L or 6.7L Cummins engines. For 2003–2007 5.9L Cummins models, removal of the factory heat shield is required to accommodate the hardware.

Note that this kit fits 1994–1998 5.9L Cummins engines only when paired with aftermarket exhaust manifolds and is not compatible with OEM manifolds from that era. Proper torque specifications should be followed during installation to ensure optimal sealing and longevity.

What's Included:

• 12 flange head exhaust bolts (M10x1.5-60mm), Grade 10.9
• 12 exhaust manifold spacers
• 2 stainless steel socket bolts (M10x1.5-35mm)
• 2 stainless steel M10 washers

Ideal For:

This kit is ideal for Dodge Ram owners and diesel enthusiasts seeking a reliable, long-lasting solution to exhaust manifold bolt failure on Cummins 5.9L and 6.7L engines. It is especially beneficial for those experiencing exhaust leaks due to stretched or corroded factory bolts, or anyone upgrading to aftermarket manifolds requiring durable hardware. The PPE Exhaust Manifold Bolt and Spacer Kit ensures peace of mind by maintaining a secure exhaust seal and preventing costly repairs down the road.
