ARP2000 is an alloy steel that can be heat treated to a higher strength level than 8740. This material choice does not establish a horsepower limit; fastener selection must also account for the application and required preload.
Selection Guidance
Thread pitch determines lug-nut compatibility, while knurl dimensions determine the press fit where a knurled stud is used. Under-head length includes more than the usable threaded section; an unthreaded nose and any spacer must be accounted for when checking engagement.
This is one replacement fastener, not a complete wheel set. Match it to the original stud specification before ordering.
Installation Considerations
Measure the hub and compare the required stud dimensions before installation. Check clearance behind the hub and inside closed-end lug nuts. Use the installation method for the exact stud design, and confirm full seating without damaging the hub.
