ARP - Custom Age 625+ Cylinder Head Studs (Evo X)
ARP - Custom Age 625+ Cylinder Head Studs (Evo X)


 
ARP's Custom Age 625+ material is a newly formulated super-alloy, which demonstrates superior fatigue cycle life, tensile strength, and toughness - with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all, it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field.

  • (10) Custom Age 625+ head studs
  • (10) parallel ground washers
  • (10) 8740 chromoly steel 12pt nuts
  • (1) 0.5 oz. pack of ARP Ultra-Torque fastener assembly lubricant

No Modification to your cylinder head or block is required as these are a direct drop-in replacement for the OEM Head Stud!
