Cylinder Head Bolt Set · 1998–2009 Toyota / Lexus 4.7L V8 2UZFE

⚠ Torque-To-Yield (TTY) head bolts must never be reused. These bolts are engineered to stretch to a precise clamping force during initial installation. Reinstalling used TTY bolts compromises that clamping force and can lead to head gasket failure, coolant leaks, or catastrophic engine damage. Always install new bolts during reassembly. Follow manufacturer torque sequence and specifications.

Precision-engineered cylinder head bolt set designed to secure the cylinder head to the engine block on the Toyota/Lexus 2UZ-FE 4.7L V8. Ensures a proper seal and maintains engine performance under extreme thermal and mechanical stress.

Each kit includes high-quality head bolts with hardened steel washers for accurate torque application and consistent clamping force. Built from durable, heat-treated carbon/alloy steel, manufactured to meet or exceed OEM quality standards. These bolts deliver excellent strength, fatigue resistance, and stability under high pressure and thermal cycling — critical for maintaining long-term engine performance and gasket sealing integrity.
