ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Push your BMW B58 engine to the limit with the ARP CA625+ Head Stud Kit. Specifically engineered for the B58 platform, these studs are manufactured from the proprietary CA625+ material, which offers significantly higher tensile strength than standard 8740 chromoly studs. This kit is the gold standard for high-boost, high-horsepower B58 builds where cylinder head lift is a major concern.
The B58 engine is known for its incredible tuning potential, but as boost levels increase, the factory head bolts can reach their limit. The ARP CA625+ kit provides the necessary clamping force to keep the cylinder head sealed under the most extreme conditions. These studs are heat-treated and precision-machined to provide a perfect fit, ensuring that your engine remains reliable whether you are on the street or the drag strip. Don't let head gasket failure end your session; upgrade to the best fastening technology available for your BMW. Elevate your build with premium components from GGCRACING.
