Tomei Head Studs - Toyota 4AG

Description

In order to secure the performance of metal head gaskets, Tomei's Reinforced Head Studs will strengthen the formation of the head and cylinder block. Original head bolts have concentrated stress at only 1/3 of its length making that section very weak. Any more torque will most likely break the bolt. These reinforced head studs allow the stress to be dispersed evenly along the threading and secure the head.
