ARP 201-5000 Main Stud Kit for BMW Inline 6 Engines

Strengthen the foundation of your BMW engine with the ARP 201-5000 Main Stud Kit, designed for M50, M52 and S52 inline 6 engines including E36 M3 models. This upgrade is essential for high performance, turbocharged and drift builds where reliability under load is critical.

Manufactured from premium 8740 chromoly steel and heat treated to extremely high tensile strength, ARP main studs provide superior clamping force compared to factory bolts, ensuring maximum crankshaft stability and long term engine durability.

Why Upgrade to Main Studs?

Main studs deliver more consistent and precise clamping than OEM bolts. This improves crankshaft alignment, reduces bearing wear and prevents main cap walk under high RPM and boost.

They also protect engine block threads and allow repeated engine assembly without loss of strength, making them ideal for performance builds and motorsport applications.
