MAHLE GS33567 Victor Reinz Cylinder Head Bolt - Set

The MAHLE GS33567 Victor Reinz Cylinder Head Bolt Set delivers precision-engineered fasteners designed to secure the cylinder head to the engine block with optimal clamping force. These bolts are the connecting elements between engine block, cylinder-head gasket, and cylinder head, delivering the clamping force necessary to seal the combustion chamber as well as the oil and coolant passages—even at extreme temperatures and pressures.

Key Features:

• Complies with all manufacturer specifications and matched perfectly to Victor Reinz head gaskets
• Contains the head bolts necessary to replace one cylinder head; torque-to-yield bolts cannot be reused, new fasteners ensure proper sealing load
• Manufactured from premium-grade alloy steel and engineered to meet stringent quality standards
• Heat treatment processes enhance tensile strength and fatigue resistance, ensuring maintained clamping force over the engine's operational lifespan
• Corrosion-resistant finish protects against rust and wear from engine fluids and extreme temperatures
• Precise thread geometry and head dimensions match OEM specifications exactly for a secure, leak-free seal

Using new head bolts for a cylinder head installation is always a good idea, however, on late-model engines that came from the factory with TTY (torque-to-yield) head bolts, replacement is an absolute necessity. Victor Reinz is trusted by OEMs and engine builders worldwide for reliable sealing under demanding conditions, making this bolt set ideal for engine rebuilds, maintenance, and performance applications.
