FAQ
Will .50 mm undersize fit my stock crank?
Only if the rod journals have been ground/honed .50 mm under. For an untouched crank, use STD size.
Do I need 6 or 12 pieces?
These are sold as pairs. Order 6 pairs to service all 6 connecting rods on a 6-cyl Cummins.
What’s the material and construction?
P-Series design with tri-metal upper shell for load capacity and bi-metal aluminum lower for scuff resistance—built to OE spec.
Torque specs or clearances included?
Follow Cummins service manual for rod bolt torque and oil clearance. Always plastigage/measure during assembly.
