Description
 

Consider these an insurance policy for your head gasket...

If you're looking to raise your boost level from factory settings but don't like the idea of lifting your cylinder head and replacing head gaskets frequently these are exactly what you need! These studs are manufactured specifically for us by A1 Technologies and utilize an 8740 chromoly material that is much stronger than the OEM head bolts. They are also provisioned with a hex broach on the top of the stud enabling you to install them with the cylinder head on the car if necessary.

While you're replacing your head studs, why not get a new head gasket to go along with them?

What makes these head studs better than the competition?

The dog point feature (shown below) seats the stud in the block and preloads the fastener for an accurate and repeatable torque sequence. We also include the new ARP Ultra Torque assembly lubricant with each set. When it comes to head stud performance properly torquing the studs is paramount and we have made every effort to ensure torque precision and repeatability!
