Ajusa 81034000 Engine Cylinder Head Bolt Set OE Replacement

The Ajusa 81034000 is an OE-quality engine cylinder head bolt set engineered as a direct replacement for original components. Cylinder head bolts are critical fasteners responsible for clamping the cylinder head to the engine block, maintaining proper compression and preventing combustion gas or coolant leaks. On many modern engines, torque-to-yield (stretch) bolts are used and must be replaced whenever the head gasket is serviced.

Key Features:

• OE-quality replacement — vehicle-specific design for a correct, confident fit
• Assembly lube included — thread and bolt head lubricant ensures accurate, consistent torque readings during installation
• Protective packaging — specialized packaging maintains bolt thread integrity until installation
• Torque sequence and spec sheet included — takes the guesswork out of proper installation
• ISO9001 and TS16949 certified manufacturing — meets the highest international quality standards
• ISO 14001 certified — produced by an environmentally responsible manufacturer

Ajusa has been manufacturing premium engine sealing and fastener components since 1972, and is recognized as an OE-certified manufacturer. Made in Spain, Ajusa's cylinder head bolt program covers over 70 million vehicles in operation worldwide, offering one of the broadest selections of European and Asian applications available in the U.S. and Canadian marketplace.
