Key Features
- Extended Length: 1.95-inch under head length (UHL) allows fitment of deeper lug nuts and aftermarket wheels requiring extra thread engagement
- High Strength Material: Forged from 8740 chromoly steel with 200,000 PSI tensile strength surpasses OEM specs for extreme load handling
- Rolled Threads: Threads formed after heat treatment resist fatigue and stripping during high torque applications
- Corrosion Protection: Black oxide finish guards against rust in harsh conditions like salted roads or track environments
- Convenient Pack Size: 5 studs per kit services one wheel, with knurled shank for secure press-in hub installation
Product Notes
- Confirm wheel offset and lug nut seat type before install to ensure proper fit

ARP Head Studs
ARP head studs replace factory head bolts with precision-machined threaded studs that provide more consistent and repeatable clamping force on the cylinder head gasket. Unlike head bolts that apply torque through both rotational and tensile forces, head studs allow the nut to be torqued concentrically on a stud that is already stationary, producing more even clamping load across the entire head gasket surface. Popular ARP Head Stud Applications ARP head studs are available for a wide range of performance and turbocharged engines including the Subaru EJ series, Honda K series and B series, Mitsubishi 4G63 and 4B11, Honda Civic and Integra, Toyota 2JZ-GTE, Nissan SR20DET and RB series, GM LS series, Ford Coyote and 5.0, and Dodge/Chrysler HEMI applications. ARP offers both 8740 chromoly and ARP2000 alloy head stud kits, with the ARP2000 material providing approximately 20 percent higher tensile strength for high-boost applications above 30 psi. Why are head studs preferred over head b...
