EMS Spec CA625+ Head Stud Kit




Introducing the new EMS Spec ca625+ studs by ARP! These studs come with washers and nuts made specifically for the ca625+ material. Custom age 625 material has an ultimate tensile strength (UTS) of ~280 ksi! This is ~90 ksi higher than the ARP2000 material most commonly used on older cars to upgrade head studs. These newer turbocharged direct-injected engines need more clamping strength! That is why we only recommend using the ca625 + studs on all EcoBoost builds. Buy once and be done!

These are highly recommended for any BaBuBu Engine Build.
