Match replacement piston rings to the exact piston fitted, including its manufacturer, reference and size. Use the ring manufacturer's application information and the listing's contents to distinguish the required ring or set.

Start with the piston reference and its standard, oversize or graded-size details where applicable. Check the ring reference specified for it. If the piston has been replaced with an aftermarket item, the original vehicle model and year may not identify the rings you need.
Where ring dimensions or other specifications are listed, compare them with the requirements for that piston. Read the stated contents to establish whether the item is an individual ring or a set and how many pistons it covers. Browse piston kits if the planned work requires the piston as well.
Use the bore or size figure alongside the exact piston and ring references. One matching dimension does not confirm that a set is specified for your piston. Resolve a missing or uncertain reference before ordering.
Use the application as a starting point, then confirm the piston actually fitted. If its brand, design or size has changed, use the replacement piston's specified ring reference instead of assuming the original rings are suitable.
Check the stated contents and quantity for the exact reference. The word “set” does not establish how many pistons it covers. Compare the supplied quantity with the requirements of the planned work before choosing how many to order.
Browse wrist pins and circlips for separate pins and retainers, or return to pistons and rings for the wider range. Check each component against the piston specification rather than assuming parts in related categories form a matched set.
Compare the complete model, year and part number before choosing a part.
