ARP Connecting Rod Bolt Kit | M9 | Porsche 993 | TurboExclusive Wave Loc design takes the risk out of replacement style rod bolts by eliminating the cause of failures in the bolt shank. Regular bolts are knurled to compensate for inconsistencies in OEM bolt holes. These knurls cut deeply into the bolt material, leaving sharp notches and enormous ''stress risers'' that promote failure. Straight shank bolts can be either too tight or loose causing cap misalignment and a variety of more serious problems.
