What material are these Mahle pistons made from?

These Mahle MS pistons are forged from a 4032 aluminum alloy. This material is known for its strength and better thermal expansion characteristics compared to other aluminum alloys, which can lead to improved engine performance and longevity.

What is the compression ratio achieved with this piston set?

With an 18cc dish volume and the specified bore and stroke, this piston set is designed to achieve a 10.0:1 compression ratio in compatible Ford FE 445 cubic inch engines.

Are these pistons compatible with all Ford FE engines?

This piston set is specifically listed for Ford FE 445 cubic inch applications. While they are designed for FE engines, it's crucial to confirm that your specific engine build, including crankshaft and connecting rod dimensions, aligns with the 4.080 inch bore, 4.250 inch stroke, 6.700 inch rod, and 0.990 inch pin specifications.

Mahle's expertise in piston manufacturing is evident in the precision of these components. The 4032 aluminum alloy offers improved strength and thermal expansion properties compared to older 2618 alloys, which helps reduce piston slap and improve overall engine longevity. Each piston weighs approximately 491 grams, contributing to a well-balanced rotating assembly. This set is intended for use in Ford FE 445 cubic inch applications, providing a well-matched component for serious engine builds.

This set includes eight pistons, ready for your next engine assembly. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or Mahle's technical documentation for specific installation requirements and compatibility with other engine components.
