For engine builders pushing the absolute limits of high-performance engineering, the ARP Custom Age 625+ Cylinder Head Stud Kit represents the pinnacle of fastening technology. While standard aircraft-quality steels and even the renowned ARP2000 alloy are impressive, the proprietary Custom Age 625+ super-alloy provides a massive leap in capability by increasing tensile strength by an additional 40,000 to 60,000 psi. This specialized hardware is engineered specifically for ultra-high-boost applications, offering superior fatigue resistance and the unique ability to maintain its structural integrity under extreme temperatures that would cause lesser materials to weaken.

With 5150's ARP head stud kit, you can securely tune up the boost on your BMW S63 engine without worrying about the cylinder heads lifting.
