What material are these Mahle pistons made from?

These Mahle MS pistons are constructed from 4032 aluminum. This material is chosen for its strength and ability to withstand higher operating temperatures and pressures, making it a popular choice for performance engine builds.

What is the compression ratio achieved with these pistons?

With a 2cc dish volume, these pistons achieve a 10.7:1 compression ratio. This is when used in conjunction with appropriate cylinder heads and head gaskets for your specific engine application.

Are these pistons suitable for all LS engines?

These pistons are specifically designed for GM L92 and LS3 376 cubic inch engines with a 4.065-inch bore. While they are part of the LS engine family, their specific dimensions mean they are not a universal fit for all LS applications.
