Olds Main Bolt Kit - Fits 350 2-Bolt

The ARP Oldsmobile Main Bolt Kit for 350 2-Bolt applications (MPN 184-5001) is a high-performance chromoly fastening solution engineered for V8 engine builders and performance machine shops. ARP's main bolt kit delivers the clamping force consistency and material integrity required to maintain block torque under sustained high-RPM and boost conditions, where factory fasteners can fail under load.

This kit features ARP's proprietary chromoly steel construction with black oxide finish, designed specifically for the 2-bolt main configuration found in Oldsmobile V8 engines. The hex head design allows precise torque application with standard wrench geometry, critical for achieving repeatability across multiple builds. Each fastener undergoes tension-control manufacturing to eliminate batch variance—a requirement for engines operating at elevated boost or nitrous levels where main bolt preload directly determines block durability and crank stability.

Engine builders, machine shops, and vintage performance enthusiasts working with Oldsmobile 350 platforms rely on this kit to upgrade from OEM fasteners that can yield under dynamic loading. The kit addresses a known weak point in early 2-bolt main designs where stock hardware limits safe displacement and boost potential. Weight: 2.11 lbs.

ARP main bolt kits represent the industry standard for aftermarket fastening solutions across domestic V8 applications, trusted by engine builders prioritizing long-term reliability over budget constraints.
