The ARP 7mgte undercut head stud kit is a must when building your 7m engine! This kit replaces your factory head bolts with ultra strong premium grade 8740 alloy studs that are heat treated to 200,000 psi! Undercut head studs provide a more even clamping force that is similar to how factory torque-to-yield head bolts are designed but with the strength that 8740 alloy provides! The kit includes studs, nuts, and ground washers. The under cut head stud kit works on the the 7mgte and 7mge engines.
