ARP Cylinder Head Stud Kit Chrome Moly Steel

The ARP cylinder head stud kit in chrome moly steel replaces factory head bolts with studs. Studs give more even, accurate clamping load across the head gasket. This helps the gasket seal in high-compression, turbocharged, supercharged, nitrous and other performance engine builds. Many people also call these head studs or head bolt studs.

Key Features:

• Chrome moly steel construction gives strong tensile properties for demanding engine applications
• Stud design applies clamping force without the twisting (torsional) stress a rotating bolt puts on the threads and gasket surface. This gives more consistent torque readings and a better gasket seal.
• Rolled threads are a hallmark of ARP fasteners. They improve fatigue strength over cut threads.
• Precision machining and quality control are applied to ARP fasteners, which are manufactured in the USA.
• Hardware is matched to the application, with nuts and washers supplied as specified for the individual kit.

Chrome moly head stud kits are a popular upgrade for street performance, racing and heavy-duty builds. They are also a good choice when you need a stronger, more repeatable alternative to stock head bolts. Because studs stay in the block during service, they make repeated head removal easier and help protect the block threads. Select the correct kit for your engine from the available options.
