ARP Custom Age 625+ Headstud Kit 03-07 6.0L

The world leader in fastener technology has released a Custom Age 625+ head stud kit for the 2003-2009 Ford 6.0L Powerstroke diesel.

Includes a set of twenty Custom Age 625+ head studs, twenty parallel ground washers, twenty 8740 chrome moly steel 12 point nuts and ten 8740 bolts and washers that secure the intake side of the head to the block. This kit also includes a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. 

All Custom Age 625+ studs are center less ground, heat treated prior to thread rolling, and machining, and are nominally rated at 270,000 psi. The steamers deliver a 40% increase in tensile strength over the OEM head bolts that are Torque to Yield (TTY).
