    1989-1991 Porsche 944 S2 Head Stud Kit by ARP

    Factory head bolts can begin to stretch with higher cylinder pressures and cause a enough space between the block and head for combustion to leak out. Not only are you losing power, you are putting your cooling system and head gasket at risk.

    Replacing the stock head bolts with ARP head studs creates a super-strong connection between the head and the block and will ensure a positive seal of the head gasket. Using ARP studs not only makes a much more solid connection, they facilitate easier R&R of the head and can be torqued more accurately.

    Since no torsional torque is required turn the entire shaft (as with bolts), there is an extremely reduced risk of variation in torque from one stud to the next, which is much better for the aluminum head.

    Features

    • Premium grade 8740 alloy which is rated far superior to "air-craft" quality alloy steels
    • Specially and precisely heat treated to 190,000 psi
    • Each stud is centerless ground to make it as close to perfectly concentric as possible
    • Thread rolled after heat-treat, which gives them about 2000% (that’s twenty times) better fatigue strength
    • The best on the market today, and the favorite of leading professional engine builders in all forms of racing

    Applications

    • 1989 - 1991 Porsche 944 S2 3.0L

    What's in the box?
