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 $100 fee. Bare cases are preferred.
