FAQ

Q: How can I be sure this connecting rod fits my engine?
A: Please verify your engine model is a Mitsubishi S4L2. You should also visually confirm the part number stamped on your old connecting rod matches 31A19-01023 or 31N19-00070. If your engine is a different variant of the S4L series, please contact us with your engine serial number for confirmation.

Q: Can this connecting rod be used in a performance or rebuilt engine?
A: Yes, this rod is manufactured to OEM specifications, making it an excellent choice for standard rebuilds and overhauls. For high-performance or high-boost applications, we recommend checking the rod’s weight and dimensions against your crankshaft and piston specifications.

Q: What is the recommended installation procedure for this part?
A: Installation should be performed by a qualified diesel mechanic. It is critical to torque the connecting rod bolts to the manufacturer’s specifications using a torque wrench. Always lubricate the bearing surfaces and bolts during assembly. It is also recommended to replace the connecting rod bolts and nuts with new ones if they are torque-to-yield type.
