What does '0.020 inch undersize' mean for these pistons?

This means the pistons are 0.020 inches smaller in diameter than the original factory size. This is common when an engine block has been bored out during a rebuild to clean up cylinder walls or increase displacement.

Do these pistons come with everything needed for installation?

Yes, this set includes eight pistons, eight sets of matched piston rings, eight wrist pins, and sixteen clips. They are ready for installation into your engine.

Are these pistons suitable for a performance build?

Mahle OE pistons are built to original equipment specifications, offering reliable performance and durability for standard engine rebuilds. For highly modified or racing applications, custom forged pistons might be considered, but these OE quality pistons are a strong choice for many builds.

Product Details

If you're rebuilding the engine in your 5.7L HEMI V8, this Mahle OE Piston With Rings Set is a solid option. This set includes eight pistons, each precisely sized at 0.020 inches undersize, along with their matched piston rings, pins, and clips, all ready for installation. Mahle is a major OE piston manufacturer, meaning these parts are built to the same standards as what originally came in your vehicle.

These pistons feature compensated ring grooves that help ensure proper ring loading and effective oil control, which is crucial for engine longevity and performance. They also incorporate expansion-controlled designs, allowing for tighter clearances. This reduces engine noise, minimizes wear, helps control emissions, and further improves oil management. Having the rings pre-mounted saves you time and ensures correct setup during your engine build.

This set is designed for a range of popular Dodge, Jeep, and Chrysler vehicles from the mid-2000s, including models like the Dodge Ram 1500, Jeep Grand Cherokee, and Dodge Charger. Make sure to check the full fitment list to confirm compatibility with your specific application.
