Part #: 4AJ1.500-2SU

Overview

The ARP Pro Series Rod Bolt Kit is engineered for automotive enthusiasts and professional engine builders seeking maximum reliability and strength in connecting rod fasteners. Designed with precision CNC-machining and advanced heat treatment processes, these rod bolts are built to withstand the intense stresses of high-performance and high-compression engines. Whether you're building a race engine, upgrading your street machine, or restoring a classic with modern reliability, these bolts provide the peace of mind that comes with superior quality fasteners.

By choosing ARP's Pro Series rod bolts, you ensure that your engine's connecting rods are secured with fasteners that offer exceptional fatigue strength and durability. This translates to improved engine integrity, reduced risk of bolt failure under extreme conditions, and the ability to safely support increased horsepower and torque. These bolts are ideal for those pushing their engines to the limit, including forced induction setups, nitrous oxide applications, and high-revving builds.

Key Features

The ARP Pro Series Rod Bolt Kit incorporates several advanced features designed to maximize performance and longevity:

• Precision CNC Machined: Each bolt is machined to exact specifications, ensuring perfect fitment and consistent quality across every set.
• Heat-Treated for Strength: The bolts undergo a proprietary heat treatment process that significantly enhances their fatigue strength, making them capable of handling the stresses of high-performance applications.
• Rolled Threads: The threads are rolled to increase fatigue strength and reduce the risk of thread stripping, providing a more reliable fastening solution.
• Material: Made from ARP2000 alloy, these bolts offer a superior balance of strength, ductility, and corrosion resistance compared to standard OEM fasteners.
• Designed for Durability: The combination of material and manufacturing processes results in fasteners that can withstand the rigors of high-revving engines and aggressive driving conditions.
• Optimal for High-Performance Builds: These bolts are suitable for engines subjected to increased power levels, including turbocharged, supercharged, or nitrous setups.
• Easy Installation: Designed to be a direct replacement for OEM bolts, requiring no modifications or special tools for installation.

Construction & Design

The ARP Pro Series Rod Bolts are crafted from ARP2000 alloy, a high-strength material specifically developed for demanding engine applications. The bolts feature a one-piece design with rolled threads, which enhances fatigue life and overall strength. The CNC-machining process ensures precise dimensions and surface finishes, promoting consistent torque and clamping force during assembly. Heat treatment further refines the material's properties, providing a reliable fastener that maintains its integrity under extreme conditions. These design choices collectively contribute to improved engine durability, reduced risk of bolt failure, and the ability to safely support increased power output.

Installation & Fitment

The ARP Pro Series Rod Bolt Kit is designed as a direct replacement for factory connecting rod bolts, making installation straightforward for experienced engine builders and technicians. No cutting, drilling, or special modifications are required. It is recommended to follow ARP's torque specifications and procedures during installation to ensure maximum clamping force and reliability. Proper tightening and re-torquing after initial run-in are essential for optimal performance and longevity of the fasteners.
