Match piston size and kit contents

A standard-size ring set, a piston kit without rings and a kit including rings are separate options. Package names alone do not tell you whether pin clips are included.

Size comes before the shopping list

This category offers standard, +0.25 mm and +0.50 mm ring listings. Do not select an oversize merely because an engine is old or worn. Establish the required size through inspection and measurement, then match the piston and ring product descriptions to that repair.

Compare what each kit leaves out

The featured standard piston kit includes pin clips but excludes rings. The featured first-oversize kit includes rings and a pin but excludes clips. Both are described as one-piston packages. Build the order from those actual contents rather than assuming every piston kit is packed alike.

Common questions

Does the standard piston kit include piston rings?

The featured standard-size piston kit excludes rings. Check the contents of the particular kit chosen; the first-oversize package has different inclusions.

Does one ring set cover the whole engine?

The ring listings state that each set contains rings for one piston. They describe four sets for a full four-cylinder rebuild. Confirm the number of cylinders you are servicing and the required size before choosing your order quantity.

Can I order an oversize using the year alone?

No. The year identifies the application, while the engine measurements and repair plan determine the required size. Compare the existing pistons and specified machining size with the selected listing before ordering an oversize piston or ring set.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
