Cylinder Head Bolt Set (26), 1HZ, 1HD-T, Land Cruiser 70 & 80 Series HZJ, HDJ

Cylinder Head Bolt Set for the 1HZ & 1HD-T engines — Toyota Land Cruiser 70 Series & 80 Series (HZJ & HDJ).

This is the complete set of cylinder head bolts required for a head gasket replacement or cylinder head rebuild on the 1HZ and 1HD-T inline-6 diesel. Head bolts are torque-to-yield (TTY) fasteners and must always be replaced — never reuse old head bolts. Reusing stretched bolts risks insufficient clamping force, head gasket failure, and coolant or oil leaks.
