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.
