Engine Head Studs and Fastener Kit for the Porsche® 928

this part is Pikes Peak tested this part is Bonneville Tested

Application: Porsche® 928 1978-86 16v and 1987-95 32v motors. Not for use with 1985-86 32v motors.

Replace Your 928 Head Studs and Fasteners! Building a Monster Motor? Do not re-use your fasteners! The metal in the fasteners will fatigue the second or third time they are torqued, and you will not get a true torque out of a used fastener. The result can be an early head gasket failure.

ALSO: If your have stroked, supercharged, or turbo'd your 928 - you can benefit from the extra clamping force that our special head studs and fasteners will provide. Our head studs are made for us by ARP, and use a special hi-strength (roughly 50% stronger than OEM) alloy.

NOTE: Porsche® used head studs on all 928 engines through 1986. They changed to bolts for 1987 to 1995 to make R&R of the heads easier with the engine in the vehicle. But: head bolt threads in the aluminum block will not take many torques/retorques before they pull out. Install head studs now, so your torsional force is steel-on-steel at the nut - and save your block!

One kit includes:
  • 18 M12 ARP long head studs
  • 2 M12 ARP short head studs
  • 20 M12 x 1.25 6 pt alloy head stud nuts
