Toyota 1KZT Hilux Hiace Surf Land Cruiser Prado OEM Head Bolt Set 90910-02112

Whether you're doing a complete top-end rebuild or replacing a blown head gasket, don’t reuse old hardware—lock it down right the first time with this complete Head Bolt Set for Toyota 1KZ-T and 1KZ-TE 3.0L diesel engines. Designed to meet or exceed OEM tensile strength and torque specs, this set ensures a reliable seal for high-compression diesel applications.

Reusing stretched head bolts can lead to improper torque, head gasket failure, or engine damage, especially in turbocharged diesel platforms.
