Designed for the S85, the V10 of the E60 M5 and E63\/E64 M6, this is a critical upgrade where sustained high-RPM operation and hard track use demand the maximum possible clamping integrity. Standard torque-to-yield fasteners stretch permanently and lose clamping load over time — ARP hardware restores and increases that clamping force, helping prevent head gasket failure, cap walk and fastener fatigue.\u003c\/p\u003e\u003cp\u003eAvailable options for this engine:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCustom Age 625+ — a 280,000 psi super-alloy with outstanding fatigue life, the recommended choice for stroker, supercharged and turbocharged builds\u003c\/li\u003e\n\u003cli\u003eARP2000 — a 220,000 psi alloy steel, the proven choice for performance builds and quality rebuilds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSupplied with ARP Ultra-Torque fastener assembly lubricant.
