Fasteners ::::: A1 Technologies H-11 Head Studs For Mitsubishi 4G63 6-bolt

These A1 Technologies head studs are the absolute strongest studs available for the Mitsubishi 4G63. These are manufactured from H-11 tool steel with a tensile strength of 260,000 PSI. These studs use 1/2" thread diameter (12mm on the block end), 1/2" nuts, and super thick washers to provide the absolute best clamping load without distortion of the cylinder head and without the worry of stretching like commonly available head studs. These head studs along with the proper head gasket will hold all the boost you can throw at them!

Fits 1990-1992 Mitsubishi Eclipse, Eagle Talon, Plymouth Laser (DSMs).
