What does '.030' mean for these pistons?

The '.030' indicates that these pistons are 0.030 inches larger in diameter than the standard factory size. This is common when an engine block is being 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 the pistons, pre-mounted piston rings, wrist pins, and clips. They are designed to be ready for installation into your engine block after the cylinders have been properly bored and honed.

Are these pistons suitable for a performance build?

These are OE-quality pistons, meaning they meet the original equipment specifications for your LT1 engine. While they are well-built and reliable for standard operation and restoration, for extreme performance builds, forged pistons are often recommended.

Product Details

If you're rebuilding the heart of your classic GM V8, like a Chevrolet Corvette, Pontiac Firebird, or even a Buick Roadmaster from the 90s, a quality piston set is crucial. This Mahle OE piston set is designed for the GM 5.7L 350 LT1 V8 engine and comes .030 inches overbore, ready to bring your engine back to life.

Mahle is one of the biggest OE piston manufacturers globally, and these pistons carry that same quality.

For your convenience, these pistons come with the pin and clips already installed, and the piston rings are mounted, so they're ready to go straight into your build.

This set includes eight pistons, enough for a full V8 engine. They are a solid option for anyone looking to restore or rebuild their LT1 engine with parts that meet original equipment specifications.
