ARP Main Stud Kit, BMW S50B30/S50B32 EURO

This ARP Main Stud Kit is designed to replace BMW 11112244286 for the S50B30 / S50B32 Euro engines that was found in E36 M3.

Upgrading from factory main bolts to ARP Main Studs is a simple, yet greatly beneficial upgrade.

ARP Main Studs offer the following benefits: - Uniform Clamping Force: ARP Main Studs provide a uniform clamping force that OEM bolts cannot.

With the improved distribution of pressure across main bearing caps comes better, more precise crank alignment for stability and longevity.

- Improved Block Stability and Rigidity: ARP Main Studs improve block rigidity and therefore stability.

This ensures maximum power transfer from the crank to the drivetrain, which in turn ensures: - Improved Throttle Response - Greater Horsepower - Higher Torque Output - Prevent Main Cap Walk: This occurs as main caps shift and move out of position, which can cause crank and engine damage - Reduced Risk of Fastener Stretching: Under high RPM applications and high loads, factory main bolts are prone to stretching and deforming.
