ARP head studs

ARP head studs are a popular upgrade for engines where higher demands are placed on fastening, strength and reliability than with standard head bolts. They are used to fasten the cylinder head to the engine block and are therefore one of the most important fasteners in the entire engine. When the engine is exposed to higher boost pressure, increased cylinder pressure, more power and heavier load, the quality of this fastening becomes even more important.

ARP is known for high material quality and precise manufacturing, which makes their head studs suitable for engines where correct preload and even clamping force are crucial for sealing and durability. ARP head studs are often chosen for performance engines, turbo engines, track cars and serious engine builds where better control of the fastening between the cylinder head and engine block is desired. Strong and stable fastening is important to help keep the head gasket sealed and ensure that the engine can operate reliably under high load and high cylinder pressure.
