Fitment:

  • 2002-2018 WRX

  • 2005-2009 Legacy GT / Outback XT
  • 2010-2012 Legacy GT

  • 2003-2006 Baja Turbo
  • 2013-2017 BRZ
  • 2013-2016 FR-S

Benefits:

  • 25% stronger than 625+ studs and 40% stonger 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 must be performed as bare cases (can not be performed after shortblock is assembled)
