High-Strength Fasteners for BMW M30 Engines

The M30 engine is legendary for its longevity, but when you begin modifying for increased boost or higher compression, the factory head bolts become a weak point. The ARP Head Stud Kit for BMW 535, 635, and 735 is the definitive solution for maintaining a perfect seal between the block and cylinder head. These studs are designed to handle the increased stress of performance upgrades, ensuring your engine remains reliable under pressure.

Why Choose ARP Studs?

• Superior Clamping: Provides significantly higher clamping force than OEM bolts.
• Durability: Manufactured from 8740 chromoly steel for maximum fatigue resistance.
• Consistency: Allows for more accurate torque readings and uniform gasket compression.
• Compatibility: Perfectly fits BMW 535i, 635CSi, and 735i models (1985-1993).

By replacing your stock bolts with these professional-grade studs, you eliminate the risk of head gasket failure caused by thermal expansion and high cylinder pressures. This kit is a must-have for any M30 engine build, whether you are restoring a classic or building a high-output street machine. Each set comes complete with all necessary hardware, including high-strength nuts and washers, to get your engine back on the road with confidence.
