ARP 4.6L Head Stud Kit

Description

Head Stud kit for 4.6 & 5.4 ALL 2 valve and 4 valve motors

ARP Pro Series cylinder head studs are cold-forged to ensure molecular integrity. They’re heat-treated prior to thread rolling and machining. All kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.

• Choose in the drop down menu between either 8740 chromoly steel head studs or ARP2000.
• When choosing which head stud to go with, the 8740 chromoly head studs have a 190,000 psi tensile strength which should be enough for most builds.  For extreme applications and high boost numbers, the ARP2000 head studs have a 220,000 psi tensile strength which will take even more abuse.
• Both ARP® head stud kits include conventional hex nuts (12 point nuts available, contact Chris to specify)
