Superior Materials and Construction

ARP is renowned for its use of premium grade 8740 alloy and proprietary ARP2000® alloy, which are far superior to aircraft quality steels. Each stud is vertically placed in special racks and precisely heat-treated to ensure maximum strength. With a heat-treatment of 190,000 psi for 8740 material and 220,000 psi for ARP2000® material, these studs offer unmatched durability.

• Heat-treated to 190,000 psi for 8740 material
• Heat-treated to 220,000 psi for ARP2000® material

Optimized Performance and Durability

ARP studs are centerless ground to achieve near-perfect concentricity, ensuring gaskets and cylinder heads align perfectly. This precise manufacturing process, combined with thread rolling after heat-treatment, provides 2000% better fatigue strength compared to studs threaded before heat-treatment. The kit also includes specially undercut studs for several engines, which more equalizes the stretch of both studs for a consistent clamping force.

• Centerless ground for precision
• Thread rolled after heat-treat for durability
• Undercut studs for consistent clamping force

This kit is not just a part; it's a guarantee of optimal engine sealing and performance for your BMW M240i or Z4 M40i.
