Reinforce Your Bottom End

The BMW M50, M52, and S52 engines are popular platforms for performance builds, but when you increase power, the main caps require additional support. The ARP Main Stud Kit for BMW 2-Bolt Main Engines provides the necessary rigidity to prevent main cap walk and bearing failure. These studs are designed to keep your crankshaft securely in place, even under the stress of high-RPM racing and forced induction.

Engineered for Performance

• Increased Strength: Manufactured from premium 8740 chromoly steel.
• Precision Fit: Designed specifically for M50, M52, S50US, and S52US engines.
• Stability: Prevents main cap movement during high-load conditions.
• Compatibility: Fits a wide range of 1991-2000 BMW 3-Series, 5-Series, and Z3 models.

Main studs offer a significant advantage over factory bolts by providing more consistent clamping force and allowing for more accurate torque settings. This is a critical upgrade for any engine build that involves performance cams, high compression, or turbocharging. By securing the bottom end, you protect your engine's most vital components and allow for higher performance thresholds. Ensure your engine build is built to last with high-quality fasteners from GGCRACING.
