Ultimate Performance.

The Fuji Racing 14mm Head Stud Kit is expertly engineered to deliver superior engine performance and unparalleled reliability. It is an indispensable component for any EJ engine build targeting a power output of 500 bhp or more.

In high-performance applications, especially at elevated boost levels, the integrity of the cylinder head attachment is critical. A robust clamping system is essential to prevent the cylinder heads from lifting off the engine block under extreme conditions, which can lead to catastrophic engine failure.

This head stud kit is constructed using high-quality materials and features precision-engineered threads and a reinforced design to withstand the immense stresses associated with high horsepower. By utilizing this 14mm head stud kit, builders can ensure a secure and stable fit for their cylinder heads, ultimately providing peace of mind while pushing their engine to its performance limits.

Choose the Fuji Racing 14mm Head Stud Kit to guarantee that your EJ engine build has the reliability necessary to handle your ambitious power goals.

Reliability.

The Fuji Racing 14mm Head Stud Kit has become a popular choice among engine builders and tuners, finding applications in a broad range of engine builds, from high-performance road cars to advanced Group A rally cars. This kit replaces the original 11mm Subaru cylinder head bolts with our meticulously engineered 14mm head studs, crafted from super high-tensile, aircraft-grade S99 steel.

One of the primary benefits of using our 14mm head studs is their significantly greater tensile strength compared to the OEM bolts. This enhanced strength allows for a more secure and durable connection between the cylinder head and the engine block, which is critical in high-stress environments such as racing.

Moreover, the increased diameter of the Fuji Racing studs contributes to greater stability within the engine assembly. This is particularly important during extreme conditions, where engine components are subjected to high pressures and temperatures. The stud and nut arrangement offers a more uniform clamping force across the cylinder head, effectively distributing loads and reducing the risk of warping or failure.

Given these advantages, it is no surprise that a growing number of successful engines—both for street use and competitive motorsports—are being equipped with the Fuji Racing 14mm Head Stud Kit. This makes it a dependable choice for anyone looking to enhance the reliability and performance of their engine build.
