Secure your engine's top end with MAHLE Original GS33504 cylinder head bolts. Designed to meet or exceed original equipment specifications, these bolts provide the precise clamping force required to maintain a reliable head gasket seal under high combustion pressures. As most modern heavy-duty engines utilize Torque-to-Yield (TTY) fasteners—which are engineered to stretch during the final torque sequence—replacing them during any head gasket service is critical to prevent bolt fatigue or failure.

  • Manufactured to OE-equivalent metallurgy and tensile strength standards
  • Ensures even loading across the cylinder head surface
  • Critical for proper head gasket compression and sealing
  • Direct replacement for factory hardware
  • Manufacturer Part Number: GS33504
