Description

Special stud bolt kit from ARP for the block (main bearing tunnel) for your BMW 3.0L 24V (B58) as used e. g. in the 240i, 440i etc.

High-performance bolts are made of high-strength, heat-treated 8740 chrome-molybdenum forged steel and are therefore ideally suited for use in racing engines.

  • Tensile strength of 200,000 psi (13.8t/cm²)
  • Absolutely perfectly rounded and straight bolts for first-class installation
  • Ten times stronger J-threads than stock screws due to thread cutting after hardening
  • Harder, more durable, more stable, and better manufactured than stock products
  • Absolute quality product for professional use
  • Reusable
