ARP is the world leader in fastener technology. Makers of the finest fasteners in the market, especially for BMW engines, ARP is the brand you can count on when you want the highest reliability possible. If you are looking for high performance from your BMW engine, then ARP Head Stud Kits are a must. All kits come complete with hardened parallel-ground washers and aerospace-quality nuts.

Upgrade the performance of your BMW N63 engine with our ARP Head Stud Kits, specifically designed for the turbocharged V-8 N63 engine. As you increase the power output of your engine beyond its factory specifications, the head and block may start to separate, causing factory bolts to stretch and fail. Our ARP Head Studs are designed to be stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. Our Custom Age 625+ kit is made from a material with a tensile strength of 260 ksi, substantially higher than the 190 ksi of the ARP 2000 head stud. It's an ideal choice for individuals who want to push the limits of their N63 builds.
