Nissan Head Stud Kit - 12pt. KA24DE

The ARP Nissan Head Stud Kit - 12pt. KA24DE is engineered for builders and enthusiasts seeking maximum cylinder head clamping force and reliability on high-performance Nissan four-cylinder engines. Head studs replace factory bolts to provide superior clamping consistency under extreme conditions, making this kit essential for forced induction, high-boost applications, or any engine experiencing elevated combustion pressures. Whether you're upgrading a street-performance build or preparing for competition, ARP studs deliver the foundation needed for durable, leak-free head gasket sealing.

This kit features premium chromoly construction with a black oxide finish, offering superior tensile strength and corrosion resistance compared to standard OEM fasteners. The 12-point nut design allows easier engagement and removal, reducing installation time and the risk of cross-threading during assembly or future maintenance. ARP's quality control ensures consistent preload across all studs, eliminating the weak-link failures common with factory bolts and providing peace of mind during high-stress engine operation.

Ideal for KA24DE Nissan four-cylinder engines commonly found in 240SX, Altima, and Frontier models, this stud set is the preferred choice of engine builders and drift competitors. Installation requires standard engine disassembly and torque specifications per ARP guidelines; following proper sequencing ensures even gasket seating and optimal performance. Whether rebuilding after a failure or proactively upgrading before adding forced induction, the ARP Nissan Head Stud Kit - 12pt. KA24DE provides proven reliability and long-term value for serious engine builders.
