Bolts, ARP2000, Toyota 1HZ, 1HZ-T, 1HD-T Head Stud Set (1/2″ UNC)
Performance Cylinder head stud, washer and nut set by ARP to suit Toyota 1HZ, 1HZ-T, 1HD-T series. These studs are 1/2" UNC to the block and will require the head bolt holes be drilled and tapped to suit. This will help gain the increased head clamping required in performance applications. They will achieve a more evenly distributed and accurate torque load compared to that of head bolts by eliminating the twisting force created during tightening. This ultimately translates into higher reliability and a lower chance of head gasket failure.
