Factory rod bolt failure is related to spun bearings how exactly?

 

Those Katech bolts must be made out of Unobtainium! I mean why else would they be the only rod bolts in the world that don't require resizing... Or maybe they just wrote better installation instructions, instead of just shrink wrapping 16 bolts to a piece of cardboard... I guess ARP figures a guy would know a thing or two about engine assembly if they were purchasing their product. FWIW the biggest problem encountered in R&R of fractured caps is lack of cleanliness, not excessive clamping force.
