1/2 Stud - 3.400 Long Broached

The 1/2 Stud - 3.400 Long Broached by ARP is a precision fastener designed for high-performance engine builds and critical structural applications. It is essential for assembling components like cylinder heads and intake manifolds in modified or race engines, where standard hardware may not endure the extreme pressures and vibrations.

Manufactured from premium-grade alloy steel, this stud features a broached design that ensures a smooth, uniform fastener body. This design resists galling and promotes even torque distribution, which is crucial for maintaining structural integrity under high-boost or high-RPM conditions. The 3.400-inch length provides the necessary reach for deep-mounted applications.

Technicians building LS-series engines, big-block Chevys, and other performance platforms will find this 1/2-inch stud ideal for their needs. ARP's rigorous quality control ensures that each stud delivers predictable preload characteristics, which are vital for calculating head gasket sealing pressure and overall engine durability.
