Pontiac Rod Bolt Kit - Fits 326-455

The ARP Pontiac Rod Bolt Kit (190-6001) is designed for high-performance engine builders and serious enthusiasts focused on reliability in Pontiac engines ranging from 326 to 455 cubic inches. This kit addresses the critical fastening needs of these engines, particularly where factory rod bolts may fail under extreme conditions such as boost, nitrous, or high-RPM applications.

Manufactured from 8740 chromoly steel, these premium bolts are heat-treated and shot-peened to enhance fatigue resistance and maintain consistent clamp load. Each fastener is individually inspected to ensure uniform tensile strength, which is essential for proper torque specifications. This attention to detail helps prevent issues like thread stripping and catastrophic failure, ensuring a reliable performance in demanding applications.

Engine builders working on Pontiac 326, 350, 389, 400, 421, and 455 engines—whether restoring classic muscle cars or constructing modern street or strip engines—will find this rod bolt kit to be a foundational upgrade for enhanced reliability. The installation process is straightforward, making it accessible for both experienced builders and those new to performance modifications.
