ARP Head Stud Kit Pro Series

The ARP Pro Series Head Stud Kit is a cylinder head stud set. It replaces factory head bolts to give stronger, more consistent clamping force. ARP Pro Series kits suit street performance, racing, and heavy-duty engine builds. Studs are also called head studs or cylinder head fasteners.

Key Features:

• Studs replace stretch-prone factory head bolts. This helps the head gasket seal under high cylinder pressure.
• Studs are threaded into the block and are not twisted into place. This allows more accurate torque readings and more even clamp load across the head.
• Made from high-strength alloy steel. The material and heat treatment are chosen for tensile strength and fatigue resistance.
• Rolled threads are used for strength and thread accuracy.
• Kits are built to help the head gasket hold in turbocharged, supercharged, nitrous, and high-compression engines.
• Kits are made in the USA. ARP is a well-known maker of performance fasteners.

Each kit includes the hardware ARP specifies for its application. For best results, follow the installation instructions and torque specifications supplied with your kit. Use the specified assembly lubricant.
