BMW E36 ARP Main Stud Kit – BMW M50/M52/S50/S52 (Part #201-5000)

Strengthen the foundation of your BMW inline-6 with the trusted reliability of ARP main studs. Designed for M50-based engines, this kit replaces the factory main bolts with high-strength studs to provide superior crankshaft stability and consistent clamping under load.

Ideal for high-performance, turbocharged, and track-driven builds, ARP main studs help prevent main cap walk and bottom-end distortion—especially under high RPM and boost. The result is improved engine durability and peace of mind when pushing your setup to the limit.

Manufactured from premium ARP material and precision-machined to exact tolerances, these studs ensure even load distribution and accurate torque readings every time.

Why Upgrade to ARP Main Studs:
Factory main bolts can stretch and lose clamping force under extreme conditions. ARP studs provide a more secure and consistent hold, making them essential for any serious engine build.
