Cylinder Head Bolts (16) Land Rover Discovery & Range Rover 3.0L V6 Supercharged AJ126 LR026143

Complete set of 16 cylinder head bolts for the 3.0L Supercharged V6 AJ126 engine. These torque-to-yield (TTY) bolts are designed to deliver precise clamping force between the cylinder head and block under high heat and combustion pressure. Because TTY bolts permanently stretch during torque-angle installation, they should not be reused. Proper clamping load is critical to maintaining head gasket seal and preventing combustion or coolant leakage.
