Arp Head Stud Kit For Subaru Ej 2.0/2.5L Dohc Ca625+

When building high-performance engines, ARP Head Stud kits are the go-to choice for professional engine builders. This is especially true for the Subaru Ej 2.0/2.5L DOHC engines, where ARP Pro Series head studs are a must for all-out competition engines.

The manufacturing process involved in their creation makes ARP Head Studs so unique. After heat-treating each stud, the centerless grinding process ensures that each stud is perfectly concentric, resulting in an exceptionally straight part.

But what really sets ARP Head Studs apart is the use of Custom Age 625 Plus material. This super-alloy is newly formulated and holds increased fatigue life cycles, tensile strength, and toughness, with total resistance to atmospheric corrosion and oxidation.

Not only is ARP the first company to have developed manufacturing and testing processes for fasteners with Custom Age 625+, but this material is also cheaper and expected to soon replace MP-35 as the material of choice in the high-strength, super-alloy field. With an average tensile strength of 280,000 psi, it's easy to see why ARP Head Studs are the top choice for engine builders.

So, if you're looking to build a high-performance Subaru Ej 2.0/2.5L DOHC engine, be sure to choose the ARP Head Stud kit with Custom Age 625+ material. Your engine will thank you.
