What It Does & How It Helps

Head studs clamp the cylinder head to the block. The factory torque-to-yield head bolts stretch and lose clamping load under high cylinder pressure, which is why a boosted or tuned diesel lifts a head and pushes a head gasket. A forged head stud kit provides far greater and more consistent clamping force, so the head gasket seals reliably at elevated power. It is essential for any head job on a modified truck and cheap insurance on a stock rebuild.
