ARP's Pro Series cylinder head stud kit is the top-end foundation for a built Hayabusa. Machined from premium 8740 alloy steel and precision heat-treated to 200,000 psi, these studs deliver stronger, more consistent clamping than any stock bolt to keep the head gasket sealed under boost and high cylinder pressure.
The hex-flange design and rolled threads ensure accurate torque loading, and studs let you tear the top end down repeatedly without wearing the block threads. Essential hardware for turbo and big-power GSX1300R builds.
