What is the advantage of Mahle pistons having expansion-controlled designs?

Expansion-controlled designs allow for smaller fitting clearances within the cylinder. This helps to reduce engine noise, minimize wear on engine components, lower emissions, and improve overall oil control.

Do these pistons come with everything needed for installation?

Yes, these pistons are ready for installation. They come with the piston rings already mounted, and the set also includes the necessary wrist pins and clips for convenience during your engine build.

What does the '.060' sizing mean for these pistons?

The '.060' indicates that these pistons are 0.060 inches larger in diameter than the standard factory size. This sizing is typically used when rebuilding an engine where the cylinder walls have been worn or bored out to accommodate a larger piston.

This set is a solid option for anyone rebuilding a 5.7L 350 V8 engine across a wide range of vehicles, including many Chevrolet, Buick, and GMC models from the 1970s through the early 1990s.
