PPE Main Stud and Girdle Bolt Kit
2004–2007 Dodge 5.9L Cummins 24-Valve
218035400
Overview:
The PPE Main Stud and Girdle Bolt Kit is engineered specifically for the 2004 to 2007 Dodge 5.9L Cummins 24-valve engines, providing a critical upgrade to the engine’s bottom end integrity. Designed for diesel enthusiasts and performance builders, this kit addresses the common failure points associated with stock main cap bolts, which can yield under stress and lead to severe engine damage. By upgrading to PPE’s premium main studs and girdle bolts, you ensure superior crankshaft alignment and maintain proper sealing at the main bearing caps, enhancing engine durability and reliability under demanding conditions.
This kit is ideal for those seeking to reinforce their engine for high-performance applications or to extend the longevity of their stock setup by preventing catastrophic failures caused by bolt fatigue.
Key Features:
The PPE Main Stud and Girdle Bolt Kit combines advanced materials and precision manufacturing to deliver exceptional strength and durability. Key features include:
- Constructed from premium chrome-moly alloy with a yield strength exceeding 215,000 psi and tensile strength over 230,000 psi
- Heat-treated studs for enhanced toughness and fatigue resistance
- Centerless ground and thread rolled studs to reduce stress concentration and improve longevity
- EDM broaching for precise stud geometry and fitment accuracy
- Black oxide finish on all studs and nuts for corrosion resistance and a professional appearance
- Compatible with the factory main cap girdle for straightforward installation
- Includes M10 girdle bolts with 12-point heads for secure fastening
- Assembly lubricant packet provided to ensure uniform load distribution and accurate torque readings
Construction & Design:
PPE’s main studs are crafted from high-grade chrome-moly steel, chosen for its superior strength-to-weight ratio and excellent fatigue resistance. Each stud undergoes a rigorous heat treatment process to optimize mechanical properties, followed by centerless grinding and thread rolling to minimize stress risers that can lead to premature failure. The studs are then broached using Electrical Discharge Machining (EDM), ensuring exceptional dimensional accuracy and consistency.
The black oxide finish not only protects against corrosion but also reduces galling during installation. The included M10 girdle bolts feature a 12-point head design, allowing for precise torque application and improved fastening security. This kit’s design maintains compatibility with the stock main cap girdle, simplifying upgrades without requiring additional modifications.
Installation & Fitment:
The PPE Main Stud and Girdle Bolt Kit is a direct fit for 2004 to 2007 Dodge 5.9L Cummins 24-valve engines, designed to replace the factory main cap bolts and studs. Installation requires standard engine disassembly to access the main bearing caps. The included assembly lubricant ensures proper torque application and uniform load distribution during installation, critical for maintaining crankshaft alignment and bearing integrity.
While professional installation is recommended to ensure correct torque specifications and assembly procedures, this kit is engineered to integrate seamlessly with existing engine components, requiring no modifications to the main cap girdle or block.
What’s Included
- Main studs constructed from chrome-moly alloy
- M10 girdle bolts with 12-point heads
- Matching nuts with black oxide finish
