What material are these pistons made from?

These Mahle MS pistons are forged from a 4032 aluminum alloy. This material is chosen for its strength and favorable thermal expansion characteristics, which are important for high-performance engine applications.

What is the compression ratio with these pistons?

When used with the specified stroke and rod length, these pistons will result in a compression ratio of approximately 9.9:1. This is a common target for many performance-oriented engine builds.

Are these pistons compatible with all camshafts?

The pistons feature a -1.6cc valve relief designed to provide clearance for most common camshaft profiles. However, it's always recommended to double-check valve-to-piston clearance during assembly, especially with aggressive camshafts.
