FAQ

Q1: Will this piston ring set fit my Isuzu 4HK1TC engine?
A: This set (YDI10160ZZ / 13011-54130) is specifically designed for 4HK1T and 4HG1 engine families. It has a 115mm bore diameter. For the 4HK1TC variant, please check your existing piston ring part number or your engine serial number to confirm compatibility, as minor revisions may exist across different production years.

Q2: What is included in the piston ring set?
A: The set includes all rings required for one cylinder: typically two compression rings (top and second) and one oil control ring assembly. For a complete engine overhaul, you will need to order multiple sets equal to the number of cylinders in your engine (usually 4 or 6).

Q3: Do you provide installation instructions or technical support?
A: While general installation is standard for a qualified diesel mechanic, we offer video technical support as part of our after-warranty service. Proper ring gap measurement and installation orientation are critical. We recommend consulting the official Isuzu service manual for your specific engine model for torque specifications and procedures.
