Head clamping load is what keeps the head gasket sealed under high cylinder pressure, and factory head fasteners are often the first thing to stretch when power goes up. This head stud kit for Subaru 2.0L FA20 4-Cylinder engines replaces the stock hardware with ARP2000 fasteners that hold clamping force more consistently, and the stud design gives more accurate, repeatable torque readings than bolts.

ARP 260-4301 Head Stud Kit Features:

• Fits Subaru 2.0L FA20 4-Cylinder engines
• 12-Point nuts
• ARP2000 alloy offers higher strength than 8740 chromoly
• Black Oxide finish
• Sold as a kit
