This is our longer stud specifically made for the SOHC EJ25 engines. This is the next step up from the ARP 260-4702 part number.

Benefits:

  • 25% stronger than 625+ studs and 40% stronger than 11mm ARP 2000's
  • Reduced shank diameter (allows for no head gasket modifying)
  • More thread engagement in block over 11mm studs
  • Uses stock alignment pins without modifying case or heads
  • Over 200ft/lbs tested for stud "pull-out" in block
  • Same kit price compared to 625+ kits (requires additional block and head machining to use)
  • Custom large diameter hardened washers to prevent embedding into head under heavy torque values and HP levels
  • Note, block machining can be done with shortblock assembled for an additional fee. Bare cases are preferred.
