What it does

Pistons and rings seal the combustion chamber and turn pressure into motion. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.

Installation & tips

• Check ring end gaps in the bore before installation and stagger the gaps.
• Bearings: Rod and main bearings are usually replaced at the same time.
• Gasket set: The engine comes apart for this job.
• Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
• Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
