The ARP 208-4302 cylinder head stud kit is designed for Honda and Acura B-Series applications using the B18A1 B18B1 1.8L engine.
Manufactured from premium 8740 chrome moly steel, these performance head studs provide increased clamping strength compared with typical factory cylinder head hardware. ARP heat-treats its 8740 material for high tensile strength, making this kit suitable for performance engine builds where increased RPM, compression, boost, or cylinder pressure places greater demands on the head fasteners.

8740 Chrome Moly Construction
ARP manufactures the 208-4302 head studs from 8740 chrome moly steel.
This material is commonly used by ARP for high-performance engine fasteners because of its combination of strength, toughness, and fatigue resistance. Proper heat treatment allows the studs to handle substantially greater clamping loads than typical factory hardware.
Performance Benefits
Upgraded cylinder head fasteners help maintain consistent clamping force between the cylinder head, head gasket, and engine block.
This becomes increasingly important in engines operating at higher RPM, increased compression, or elevated cylinder pressure from turbocharging or supercharging.
Recommended Use
- B18A1 B18B engine rebuilds
- Naturally aspirated performance builds
- Turbocharged B18A1 B18B1 applications
- Supercharged applications
- High-RPM engine builds
- Track and motorsports use
- Performance cylinder head installation
