FAQ

Q: Is the Mn137979 piston ring set compatible with the Mitsubishi 4D56 engine?
A: Yes, this set is engineered specifically for the 4D56 engine used in L200 and other Mitsubishi models. It matches OEM dimensions and material specifications for a direct fit.

Q: Do I need to replace all rings during an engine rebuild?
A: It is highly recommended to replace all rings (top, second, and oil control) as a set to ensure even wear and optimal compression. Reusing old rings can lead to oil consumption and reduced performance.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified mechanic. Ensure the cylinder bores are properly honed and cleaned. Follow the engine manufacturer’s torque and gap specifications for each ring. We recommend using assembly lubricant during installation.
