PPE Main Stud and Girdle Bolt Kit: Dodge Ram Cummins 6.7L 2007.5-2018

PPE Main Stud and Girdle Bolt Kit

2007.5–2018 Dodge Ram Cummins 6.7L

218035500

Overview:

The PPE Main Stud and Girdle Bolt Kit is engineered specifically for the Dodge Ram Cummins 6.7L engines produced between 2007.5 and 2018. This kit addresses a critical engine component: the main cap bolts, which are essential for maintaining crankshaft alignment and ensuring proper sealing at the main bearing caps. In high-performance or even stock applications, factory main cap bolts can stretch or yield over time due to repeated stress cycles, potentially leading to catastrophic engine failure. PPE’s Main Stud Kit offers a robust solution designed to enhance engine reliability and durability under demanding conditions.

Ideal for diesel enthusiasts, performance builders, and anyone seeking to reinforce their engine’s bottom end, this kit provides peace of mind by significantly reducing the risk of main cap bolt failure.

Key Features:

Designed with precision and durability in mind, the PPE Main Stud and Girdle Bolt Kit includes:

• Premium chrome-moly alloy studs with a yield strength exceeding 215,000 psi and tensile strength over 230,000 psi
• Heat-treated studs for enhanced strength and fatigue resistance
• Centerless ground and thread-rolled studs to minimize stress concentrations and improve longevity
• EDM broaching for precise stud geometry and fitment
• Black oxide finish on all studs and nuts for corrosion resistance and a professional appearance
• Compatibility with the stock main cap girdle for straightforward installation
• M10 girdle bolts featuring a 12-point head for secure fastening
• Assembly lubricant packet included to ensure uniform load distribution and accurate torque readings

Construction & Design:

The studs are crafted from high-grade chrome-moly alloy, a material known for its exceptional strength-to-weight ratio and resistance to fatigue. Each stud undergoes a rigorous heat treatment process to optimize mechanical properties, followed by centerless grinding and thread rolling to reduce stress risers that can lead to premature failure. The use of EDM (Electrical Discharge Machining) broaching ensures precise and consistent stud dimensions, critical for maintaining proper main cap alignment and engine integrity.

The black oxide finish not only enhances corrosion resistance but also provides a sleek, professional look. The included M10 girdle bolts with 12-point heads are designed for maximum torque application and durability, complementing the studs perfectly.

Installation & Fitment:

This Main Stud and Girdle Bolt Kit is a direct fit for Dodge Ram Cummins 6.7L engines from 2007.5 through 2018 and works seamlessly with the stock main cap girdle. Installation requires standard engine disassembly procedures and proper torque specifications to ensure optimal performance and reliability. The included assembly lubricant packet aids in achieving accurate torque readings and uniform load distribution during installation.

While professional installation is recommended to ensure correct fitment and torque, experienced enthusiasts with the appropriate tools can perform the upgrade to enhance engine durability.

What's Included:

• Chrome-moly main studs (heat treated, centerless ground, thread rolled)
• Black oxide finish nuts
• M10 12-point girdle bolts
• Assembly lubricant packet

Ideal For:

This kit is perfect for diesel performance enthusiasts, engine builders, and anyone looking to upgrade the bottom end of their Dodge Ram Cummins 6.7L engine. It is especially beneficial for vehicles subjected to heavy towing, high horsepower builds, or extended use under demanding conditions where stock main cap bolts may be prone to failure.
