M30 ARP Head Stud Kit

When you're building boost or chasing high horsepower on an M30, OEM head bolts aren't enough. ARP head studs deliver superior clamping force, consistent torque values, and can be reused across multiple builds — something no factory bolt can offer.

• Higher clamping strength than OEM head bolts
• Reusable hardware — unlike your factory bolts
• Precision-engineered by ARP, the world leader in fastener technology
• Superior clamping force for high-boost and high-compression applications
• Fits all M30 engines
• Replaces BMW part number 11120621144

We run these in many of our own in-house builds and are fully confident in the fit, finish, and performance of every ARP stud kit we carry.
