ARP Head Stud Kit for Honda VTEC Engine

The ARP head stud kit for Honda VTEC engines replaces factory cylinder head bolts with high-strength studs. They are built to improve clamping force and head gasket sealing in naturally aspirated, turbocharged, and supercharged builds. Engine builders also call them cylinder head studs or head bolt upgrade kits.

Key Features:

• Stud design: Studs thread into the block and hold the head with nuts. This gives more even, accurate clamp load than head bolts, which twist into the block as they are tightened.
• High-strength alloy steel: ARP manufactures its fasteners from premium alloy materials. These are selected for tensile strength and fatigue resistance in demanding engines.
• Rolled threads: Threads are rolled after heat treatment, a process that improves strength and fatigue life.
• Precision machining: Components are made to tight tolerances for consistent fit and torque accuracy.
• Hardware included: Kits are supplied with the nuts and washers needed for installation, and with assembly lubricant.

ARP is a well-known name in performance and racing fasteners, and builders use its products in street, track, and competition engines. These head studs help keep the head gasket sealed under higher cylinder pressures and boost. Installation instructions are provided with the kit, and following the torque specifications and lubricant guidance is recommended for proper clamp load.
