ARP 247-4204 Diesel Custom Age 625+ Head Stud Kit

The ARP 247-4204 Diesel Custom Age 625+ Head Stud Kit is designed for 1998.5-2024 Dodge Ram 2500 and 3500 models equipped with 5.9L or 6.7L Cummins 24-valve engines. Using ARP’s proprietary Custom Age 625+ material, this kit delivers exceptional tensile strength and clamping force, making it an ideal solution for high-performance or heavily modified engines operating under increased boost and combustion pressures.

Detailed Product Description

Exceptional Material Composition

Manufactured from Custom Age 625+, a chromium-cobalt-nickel alloy, this head stud kit provides unmatched strength and fatigue resistance. The material is fully resistant to corrosion and oxidation, ensuring consistent performance even in demanding conditions. This durability makes it a superior choice for diesel engines subjected to extreme stresses.

Unmatched Tensile Strength

The ARP 247-4204 head studs boast a tensile strength of 260,000 to 280,000 psi and a yield strength between 235,000 and 255,000 psi. These characteristics allow the studs to maintain cylinder head integrity under high combustion pressures, preventing head lifting and ensuring long-term engine reliability.

Precision Engineering for Reliability

Each stud undergoes a meticulous heat treatment process while vertically aligned to ensure uniform heat penetration. Centerless grinding guarantees perfect concentricity, while threads are rolled post-heat treatment to significantly enhance fatigue resistance. A black oxide finish protects the studs from corrosion, ensuring durability in all conditions.

Comprehensive Kit for Installation

The ARP 247-4204 kit includes 26 Custom Age 625+ studs, chrome moly steel 12-point nuts, and parallel-ground washers. This comprehensive package ensures a secure, precise installation, facilitating optimal engine performance without the need for additional components.

Compatibility and Application

This head stud kit is designed for 1998.5-2024 Dodge Ram 2500 and 3500 models with 5.9L or 6.7L Cummins 24-valve diesel engines. It replaces factory head bolts with a stronger, more reliable solution, making it particularly beneficial for engines subjected to high boost or heavy-duty usage.
