Product Details
The ARP head stud kit for the BMW S55 replaces the factory cylinder head bolts with high-strength ARP studs/bolts that clamp the cylinder head to the block. Designed for the S55, the twin-turbo straight-six of the F80 M3 and F82 M4, this is a critical upgrade where forced induction places extreme stress on the head gasket, main caps and connecting rods. 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.
Available options for this engine:
- Custom Age 625+ — a 280,000 psi super-alloy with outstanding fatigue life, the recommended choice for stroker, supercharged and turbocharged builds
- ARP2000 — a 220,000 psi alloy steel, the proven choice for performance builds and quality rebuilds
Supplied with ARP Ultra-Torque fastener assembly lubricant and torqued in stages to ARP’s specification. After initial assembly, complete a full heat cycle and re-torque the fasteners for a lasting, reliable seal.
