MAHLE GS33486 Engine Cylinder Head Bolt Set

The MAHLE Original GS33486 Engine Cylinder Head Bolt Set provides OE-quality fasteners designed to deliver the precise clamping force necessary to seal combustion chambers, oil passages, and coolant passages—even under extreme temperatures and pressures. Distributed under the Victor Reinz brand, this cylinder head bolt set meets or exceeds original equipment specifications for reliable engine reassembly.

Key Features:

• Contains all head bolts necessary to replace one cylinder head
• Engineered to exact OE specifications for proper sealing performance
• Essential for engines equipped with torque-to-yield (TTY) head bolts that cannot be reused
• Manufactured from high-grade steel with natural finish
• Designed to work perfectly with Victor Reinz head gaskets
• Packaged in shrink-wrapped tray for parts verification and protection

When reassembling a cylinder head, using new fasteners is critical—especially on late-model engines with TTY head bolts. These specialized bolts are designed to stretch beyond their elastic limit during installation, which means they permanently deform and must be replaced to ensure proper clamping force and head gasket seal integrity. Trust MAHLE Original for precision-engineered fasteners backed by decades of OE supplier experience.
