When one lets go, you are not “a little down.” You are parked. The BPS 4059429 is the \u003cstrong\u003esaw-cut \u003c\/strong\u003e rod these engines were built with — flat machined cap faces, the right big-end bore, and the strength to take a beating mile after mile.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eThis replaces Cummins 4059429, 4059449, and 4923749. New pin bushing is pressed in so you are not waiting on machine work. On the bench it is obvious: smooth cap face, no fracture pattern, no ID hole in the cap. Use \u003cstrong\u003esaw-cut rod bearings only\u003c\/strong\u003e. Fractured bearings do not belong in this rod, period.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003eIf you are rebuilding an ISX, QSX, or Signature and the rod you pulled is saw-cut, this is the part that gets the truck back to making money without the Cummins dealer invoice. Buy one and fix the hole that failed, or buy the set of 6 and walk away knowing the bottom end is right.\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"auto\"\u003e\n\u003cli\u003eSaw-cut cap for earlier ISX \/ QSX engines\u003c\/li\u003e\n\u003cli\u003eDirect replacement for Cummins 4059429 \/ 4059449 \/ 4923749\u003c\/li\u003e\n\u003cli\u003eNew pin bushing installed\u003c\/li\u003e\n\u003cli\u003eRequires saw-cut connecting rod bearings only\u003c\/li\u003e\n\u003cli\u003eBuilt for the engines that still dominate the rebuild market\u003c\/li\u003e\n\u003cli\u003eAvailable as a single rod or complete set of 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eOEM Cross References\u003c\/strong\u003e\u003cbr\u003e4059429, 4059449, 4923749, 4059429RX, 171634\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003cbr\u003eCummins ISX, QSX, and Signature-series engines using the saw-cut connecting rod.
