Automotive Racing Products (ARP) Crankshaft Main Cap Bolt 134-5001; High Performance Hex Head Bolt Black Oxide 8740 Chromoly for Chevy 262-400

Fits small block Chevrolet with large journal, 2-bolt mains ARP's 134-5001 main bolts are designed to meet the exacting standards and demands of professional engine builders and yet they are priced below what you might expect for a product with quality this high. The 134-5001 are far superior to any other main bolts on the market. They have a tensile strength rating of 180,000 psi and all bolts feature generous under-head radius to help provide even load distribution and accurate torque readings. The threads are rolled after heat treating, a process that is hard on the tooling but produces a much stranger thread.
