Key Features

ARP Pro Series cylinder head studs are crafted from high-quality materials and feature advanced manufacturing processes to ensure molecular integrity and consistent performance. Key features include:

• Cold-forged construction that enhances strength and durability, ensuring the fasteners withstand extreme engine conditions.
• Heat-treated prior to thread rolling and machining, providing excellent tensile strength and resistance to fatigue.
• Complete with hardened parallel washers that distribute load evenly across the head gasket, promoting accurate torque readings and reducing the risk of gasket failure.
• Available with 12-point nuts for easier installation and removal, especially in tight engine bays or when working with multiple fasteners.
• Designed to fit a variety of Buick engines from 2011 to 2025, covering multiple models and configurations.
• Precision thread rolling and machining processes ensure consistent dimensions and reliable performance.
• Manufactured to meet or exceed OEM standards, providing a high-quality upgrade for performance builds.
• Corrosion-resistant finishes extend the lifespan of the fasteners, maintaining their strength and appearance over time.
• Suitable for both stock rebuilds and high-performance applications where head bolt integrity is paramount.

Construction & Design

The ARP Head Stud Kits feature a robust, cold-forged steel construction that guarantees high tensile strength and longevity. The studs are heat-treated to optimize their molecular structure, ensuring they can withstand the intense pressures and thermal cycles experienced in high-performance engines. The threaded portion is precisely machined to provide a smooth, accurate fit, reducing the risk of thread stripping or galling during installation.

The inclusion of hardened parallel washers ensures even load distribution across the cylinder head and gasket interface, which is essential for maintaining proper sealing and preventing head lift under boost or high compression. The 12-point nuts are designed for easy installation and removal, especially in tight spaces, and are also heat-treated for added strength. Overall, the design emphasizes durability, precision, and ease of use, making these studs a reliable upgrade for any Buick engine rebuild or performance enhancement.

Installation & Fitment

The ARP Pro Series Head Stud Kits are designed for straightforward, bolt-on installation. They replace the factory head bolts, providing a more secure and reliable fastening solution. Installation typically involves removing the cylinder heads, cleaning the mating surfaces, and installing the studs with the provided washers and nuts. No cutting, drilling, or special modifications are required, making this upgrade suitable for both professional mechanics and experienced DIY enthusiasts.

Proper torque specifications should be followed as per ARP's instructions to ensure optimal clamping force and engine integrity. Using ARP's thread lubricant is recommended to achieve accurate torque readings and prevent galling during assembly.
