What material are these Mahle pistons made from?

These Mahle MS pistons are constructed from 2618 aluminum. This material is chosen for its strength and ability to withstand high temperatures and pressures found in performance engines.

What is the compression ratio achieved with these pistons?

When installed with appropriate cylinder heads, these pistons contribute to a 10.6:1 compression ratio. The -5.8cc dish volume is a key factor in achieving this ratio.

Are these pistons compatible with all GM LS engines?

These pistons are specifically designed for GM LSX engines with a 370 cubic inch displacement. They feature a 4.030 inch bore and are intended for use with specific rod and pin dimensions. Always verify compatibility with your specific engine build.
