Pontiac Rod Bolt Kit - Fits Iron Duke 4-Cyl.

The ARP Pontiac Rod Bolt Kit (191-6001) is a high-performance connecting rod fastening solution engineered for Pontiac Iron Duke 4-cylinder engines. This set of eight chromoly bolts delivers the critical clamping force and fatigue resistance required in demanding engine applications where stock fasteners cannot reliably handle elevated horsepower, boost pressure, or sustained high-RPM operation.

Manufactured from 8740 chromoly steel and finished in black oxide, these 11/32-inch bolts provide superior tensile strength and load-carrying capacity compared to standard fasteners. The black oxide coating offers corrosion resistance while maintaining precise torque-to-yield characteristics essential for proper preload and bolt stretch. ARP rod bolts are manufactured to exacting tolerances and include detailed installation and torque specifications, ensuring consistent, repeatable clamping force across all eight cylinders.

This kit is purpose-built for engine builders, performance enthusiasts, and rebuild shops working on Iron Duke applications—whether upgrading from OEM fasteners during an overhaul or assembling a modified short block destined for increased boost or displacement. The eight-bolt count matches the complete rod complement required for a full bottom-end installation, eliminating the need to source fasteners separately.

ARP is recognized among engine builders and machine shops for rod bolt engineering. This Pontiac rod bolt kit reflects the same design and quality control applied across their full lineup of powertrain fastening solutions. Proper installation requires a quality torque wrench and adherence to the supplied specifications; improper torque or installation procedure will compromise performance and reliability.
