ARP 203-4706 Custom Age 625+ Head Stud Kit, Toyota Supra B58

Description

The ARP 203-4706 head stud kit is made for Toyota Supra B58 engines.

Head studs clamp the cylinder head more evenly and more accurately than head bolts. A stud is threaded into the block once and stays put, so torque applied to the nut goes into stretching the stud and not into twisting it. That gives a more consistent clamp load across the head gasket, which matters most on boosted, high-compression, and race engines.

This kit uses ARP Custom Age 625+, a super-alloy rated at 260,000 psi tensile strength with excellent corrosion resistance, for engines that need the highest clamp load.
