Kong LS9 Head Stud Kit

The Kong LS9 Head Stud Kit is designed specifically for the unique deck height and cylinder head requirements of the LS9 engine. Manufactured from premium ARP 2000 material, these studs provide the clamping force needed to keep cylinder heads securely sealed in high-boost, high-horsepower applications.

Unlike universal LS head stud kits, these studs are the correct length for LS9 engines, ensuring proper thread engagement and accurate installation. Whether you’re upgrading your factory supercharged ZR1 or building a max-effort combination, these head studs are an essential reliability upgrade.

Proven to withstand boost levels exceeding 20 PSI, the Kong LS9 Head Stud Kit helps maintain head gasket integrity under extreme cylinder pressures, making it an ideal choice for aggressive street builds, race cars, and high-performance applications.
