Match the fitted piston

Identify the piston manufacturer, reference and size before choosing separate pins or clips. Use the component specified for that piston, checking the vehicle application as well. If an aftermarket piston is fitted, the original vehicle details alone may not establish the correct replacement.

Compare dimensions and pack details

Check any listed pin dimensions or clip size and type against the piston manufacturer's specification. Read the selling unit and quantity carefully; a category name or plural title does not establish the number supplied. If you need the piston too, compare the stated contents of piston kits before ordering separate parts.

Is a wrist pin also called a gudgeon pin?

Yes. Both names are used for the pin in the piston assembly. Use the exact part reference and specification when comparing listings, as the name alone does not identify the correct pin.

Can I choose a pin or circlip by diameter alone?

Check the complete specification and the component reference required for the piston. One dimension is not a substitute for the stated application, pin dimensions or clip type. Confirm any missing details before ordering.

Are circlips supplied as a pair?

Check the exact listing's selling unit and pack quantity. Do not assume a pair from the plural wording or the image. Order the required number using the stated quantity supplied.

Do I need separate clips when ordering a piston kit?

Read the kit's supplied-parts list first and compare it with the requirements for the planned work. For other components, browse piston rings or the wider pistons and rings category, checking each item against the same piston reference.

Compare the complete model, year and part number before choosing a part.
