ARP Head Stud Kit High Performance Chrome Moly

The ARP High Performance Chrome Moly head stud kit is a cylinder head stud and fastener set. It gives a stronger, more consistent clamping load than factory head bolts. It suits street performance, towing, and many racing builds. These cylinder head studs are also known as head bolts or head fastener kits.

Key Features:

• Chrome moly construction: The studs are made from chromemoly alloy steel for strength and durability.
• Rolled threads: ARP rolls the threads after heat treatment. This improves fatigue resistance and thread strength.
• Even clamping force: Studs apply load straight along the axis, with no twisting during installation. This helps the head gasket seal and keeps cylinder bores more stable.
• Hardware included: Kits come with the nuts and washers needed for installation, as specified for each part number.
• Assembly lubricant: ARP provides special lubricant with its fasteners to get correct torque and preload.

Benefits:

• Better head gasket sealing under higher cylinder pressure, boost, or nitrous.
• Reusable fasteners that suit repeated engine rebuilds.
• Made in the USA by ARP, which is known for performance fasteners.

Follow the instructions supplied with the kit for installation. Use the stated torque values and the ARP lubricant supplied. Choose the exact kit for your engine from the individual listings.
