S54 ARP 625+ Custom Age Head Studs

Turn up the BOOST!  This ARP Custom Age 625+ Head Stud Kit is specifically designed for the BMW S54 engine, serving as a direct replacement for BMW OEM head bolts # 11127831862. We collaborated with ARP to engineer a kit with superior clamping force and enhanced head gasket sealing for boosted applications, eliminating risk of cylinder head lift. Custom Age 625+ studs are the ONLY choice for high-performance builds, including stroker, supercharged, and turbocharged S54 engines, where cylinder pressures are elevated, placing extra strain on the head gasket and fasteners. Because 625+ studs utilize a special alloy construction, they offer a tensile strength of 280,000 PSI–over 60,000 PSI greater than the standard ARP 2000 kit #201-4303.
