ARP Head Bolt Kits | Multiple Oldsmobile Fitments (180-3700)

The ARP High Performance Series Head Bolt Kit for Oldsmobile applications is a set of durable, high-strength fasteners designed to ensure reliable cylinder head retention under demanding conditions. Constructed from chromoly steel and finished with a black oxide coating, these bolts are rated at 180,000 psi, making them 15 percent stronger than standard Grade 8 fasteners. The kit features 12-point head fasteners with a 7/16-inch-20 thread size, offering improved torque application and reduced risk of stripping. The inclusion of washers and the option for reduced wrenching hex or 12-point heads facilitate easier installation and re-torque procedures, helping to maintain optimal cylinder head sealing and performance.

Designed for a variety of Oldsmobile models, these head bolts are suitable for engines requiring a reliable, high-strength fastening solution. They are ideal for performance builds, rebuilds, or maintenance where enhanced durability and torque retention are critical. The bolts are intended as direct replacements for OEM fasteners, providing a secure fit for street or performance applications. Installation involves standard bolt tightening procedures, and the kit includes all necessary washers. These ARP head bolts are suitable for use in engines that demand superior clamping force and long-term reliability.
