With an optimized design, enhanced reliability, and dependable strength, the Custom Age 625+ head studs available in ARP’s 250-4302 kit are the best you can get for your Ford 6.7L Power Stroke diesel engine. The studs get their durability from being centerless ground and heat treated before thread rolling and machining. They are nominally rated at 260K PSI tensile strength and are reusable.
The kit includes a set of 36 Custom Age 625+ studs, nine M8 ARP2000® head studs, 45 chrome-moly-steel 12-point nuts, 45 parallel ground washers, and a 1 oz pack of ARP Ultra-Torque fastener assembly lubricant.
