ARP Cylinder Head Stud Kit High Performance Chrome Moly

The ARP cylinder head stud kit is a high-performance replacement for factory head bolts. It is designed to give engine builders stronger, more consistent clamping force for street performance, racing, and forced-induction builds. Also known as head studs or a cylinder head bolt set, these kits help keep the head gasket sealed under high cylinder pressure.

Key Features:

• Chrome moly construction: Made from high-strength chromium-molybdenum alloy steel for durability and fatigue resistance.
• Studs instead of bolts: Studs apply clamping load in pure tension. This helps with accurate torque readings and more even gasket loading, and it reduces thread wear in the block deck.
• Rolled threads: ARP rolls threads after heat treatment. This increases fatigue strength and thread accuracy.
• Complete hardware: Kits typically include the hardware needed for installation, such as nuts and washers, as specified for each part number.
• Assembly lubricant: ARP supplies a specific lubricant with its fasteners. Using it helps you reach correct, repeatable preload when you follow the torque instructions.

ARP is a well-known maker of high-performance fasteners, with products made in the USA. These stud kits suit engine rebuilds and performance upgrades where stock fasteners may stretch or lose clamp load. Always follow the torque specifications and installation instructions that come with the kit.
