Troubleshooting & FAQ
How do I know if these piston rings will fit my engine?
Verify your engine model and year against the compatibility tables on this page. It is crucial to match your complete engine model number (e.g., F75TLR) to ensure a proper fit. If you are unsure, please contact us with your engine details before purchasing.
What are the signs of a failing piston ring?
Common symptoms of worn or damaged piston rings include excessive oil consumption, blue or grey exhaust smoke, noticeable loss of engine power, and poor results from a cylinder compression test.
Is this a complete set for one piston?
Yes, this package contains one complete ring set required to service a single piston. If you are rebuilding multiple cylinders, you will need to purchase one set for each piston.
Does the 79mm diameter refer to the piston or the cylinder bore?
The 79mm dimension refers to the standard cylinder bore diameter for which these rings are designed. This ensures a tight seal for optimal compression.
