Head Studs

The ARP Pro Series Head Stud Kit (154-4001) is engineered for enhanced engine reliability and performance. These studs are cold-forged from 8740 chromoly material, ensuring superior molecular integrity and strength. They undergo heat treatment before thread rolling and machining, further reinforcing their durability under high stress. Each kit includes twenty 7/16 in.-20 studs, complete with twenty hardened parallel washers for even load distribution and precise torque readings. The black oxide finish provides corrosion resistance. These studs are compatible with both stock and aftermarket cylinder heads that require 7/16'' bolts, making them a versatile choice for engine builders. The ARP 154-4001 head stud kit is designed for a wide range of Ford applications, including but not limited to: 1966-1970 Ford Fairlane, 1968-1995 Ford Mustang, 1969-1996 Ford F-Series, 1969-1996 Ford Bronco, and many Mercury and Lincoln models from similar eras. Specific fitment details are extensive and cover various engine configurations from the 1960s through the 1990s and early 2000s.
