Bolts, ARP2000, Toyota 1HZ, 1HZ-T, 1HD-T Head Stud Set

These studs can replace the existing cylinder head bolts on your engine and provide increased head clamping which is required in high performance applications to prevent a head gasket failure. This is done by allowing a more evenly distributed and accurate torque load compared to a standard head bolt. Using an ARP2000 stud will eliminate the twisting force created during tightening. 30psi++
