AR9994215-CA Arp Nissan Rb30 Et 11 Mm Head Studs Ca625+, Sohc, Stock Diameter

Description

Maintaining consistent cylinder head clamping pressure is critical to engine performance and reliability. ARP’s NISSAN RB30 ET 11 MM Head Studs provide a robust solution, engineered to resist stretching and maintain torque under high thermal and mechanical loads.

Constructed from ARP’s proprietary CA625+ alloy, these studs deliver exceptional tensile strength and fatigue resistance, which means your engine head stays securely fastened during intense operation. This alloy’s superior durability reduces the risk of stud failure and subsequent engine damage.

Measuring 16.50 cm in length with a stock diameter of 11 mm, these head studs are specifically designed for the NISSAN RB30 SOHC engine, ensuring precise fitment without modifications. This exact sizing preserves factory tolerances and simplifies installation, saving time and preventing compatibility issues.

Weighing 2.5 kg, the studs balance strength with manageable mass, contributing to overall engine efficiency without unnecessary weight. Their dimensions (14.50 cm width and 6.00 cm height) are optimized for secure engagement in the engine block and cylinder head, enhancing load distribution and reducing gasket wear.

The studs’ stock diameter is critical for maintaining OEM sealing surfaces, preventing head gasket failure caused by uneven clamping or over-torquing common with inferior fasteners. This ensures a lasting seal, guarding against coolant and compression leaks that degrade engine performance.

Designed for professional engine builders and performance enthusiasts, these ARP head studs offer peace of mind through precision engineering and premium materials. Installing them significantly reduces the risk of cylinder head movement, which can cause warping or cracking under high RPM or boost conditions.

Choose ARP’s NISSAN RB30 ET 11 MM Head Studs to enhance your engine’s structural integrity. Their exact fitment, advanced CA625+ alloy construction, and optimized dimensions deliver durability and consistent performance that aftermarket competitors cannot match.
