ARP High Performance Rocker Arm Stud 7/16-20 Purple Hex Bolt

Description

Product Overview

The ARP High Performance Rocker Arm Stud is engineered for the most demanding automotive applications. Constructed from Grade 10.9 alloy steel, the stud offers exceptional tensile strength and durability, ensuring it can handle high torque loads without deformation. The 7/16-20 thread size follows a right‑hand, full, coarse pitch specification, providing a secure and repeatable fit in a wide range of engine configurations. A distinctive painted purple finish not only adds visual identification but also offers an additional layer of corrosion resistance, extending the service life of the component. The hex head design, paired with a flat head style, allows for easy installation using standard tools while maintaining a low profile that fits within tight engine bays. Every stud is manufactured to ARP’s stringent quality standards, guaranteeing consistent performance across each unit. Whether you are rebuilding a classic vehicle, upgrading a performance engine, or performing routine maintenance, this stud delivers the reliability and precision required for optimal engine operation.

Usage

This rocker arm stud is ideal for high‑performance street cars, race‑ready builds, and heavy‑duty trucks that demand robust fastener solutions. It is designed for vehicle‑specific installations, meaning it matches the OEM specifications for a variety of makes and models, ensuring a seamless fit without the need for additional modifications. During installation, the stud’s 7/16-20 thread engages cleanly with the corresponding rocker arm hole, providing a firm grip that resists loosening under the extreme vibrations and thermal cycles typical of high‑output engines. The flat head style distributes load evenly across the mating surface, reducing the risk of stress concentrations that could lead to premature failure. Technicians appreciate the hex head’s accessibility, which allows for torque application with standard socket wrenches, while the painted purple coating aids in quick visual identification during assembly and inspection. This product is also suitable for aftermarket performance upgrades, where increased horsepower and torque place additional demands on engine components. By choosing the ARP stud, users benefit from a component that not only meets but exceeds OEM standards, delivering confidence in both daily driving and competitive environments.

FAQ

What makes the ARP rocker arm stud different from standard bolts?

The ARP stud is manufactured from high‑grade 10.9 alloy steel, offering significantly higher tensile strength than typical automotive bolts. Its precise 7/16-20 thread pitch, combined with a flat head design, provides a more secure connection that resists loosening under extreme vibration and heat. Additionally, the painted purple coating not only aids in visual identification but also adds a protective layer against corrosion, extending the component’s service life.

Can this stud be used in both street and race applications?

Yes. The stud is engineered to meet OEM specifications while also exceeding them, making it suitable for everyday street driving as well as high‑performance racing environments. Its robust construction handles the increased loads and thermal cycles associated with race‑tuned engines, and the flat head design distributes stress evenly, reducing the likelihood of failure in both scenarios.

How do I determine the correct torque setting for installation?

ARP provides detailed torque specifications in the product documentation and on their website. For the 7/16-20 stud, the recommended torque typically falls within the range of 70‑80 ft‑lb, but the exact value may vary depending on the specific engine model and the material of the mating components. Always consult the vehicle’s service manual and follow ARP’s guidelines to achieve optimal performance.

Is the stud compatible with all engine types?

While the stud conforms to a standard 7/16-20 thread size, compatibility depends on the engine’s design and the rocker arm’s mounting requirements. It is vehicle‑specific, meaning it matches the OEM part numbers for many popular makes and models. Users should verify the part number (1357101) against their vehicle’s specifications to ensure a proper fit.

What support does ARP offer if I encounter installation issues?

ARP provides extensive technical support through phone, email, and online resources. Their engineering team can assist with installation questions, torque settings, and troubleshooting. In addition, ARP’s return policy allows for easy replacement or refund if the product does not meet expectations, ensuring customers have confidence throughout the purchase and installation process.
