What material are these Mahle pistons made from?

These Mahle MS pistons are constructed from 4032 aluminum alloy. This material is chosen for its strength and durability, offering good resistance to high temperatures and pressures common in performance engines.

What is the compression ratio achieved with these pistons?

With a -20cc dish volume and designed for specific stroke and rod lengths, these pistons achieve a 10.8:1 compression ratio. This is a popular target for many performance engine builds.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California. It is important to check local emissions regulations before purchasing and installing engine components.

Product Details

If you're rebuilding the top end of your Ford FE engine and aiming for serious performance, this Mahle MS Piston Set is a solid choice. Designed for 482 cubic inch displacements, these pistons are built to handle the demands of a high-performance build. They feature a 4.250-inch bore and a 4.250-inch stroke, working in harmony with a 6.700-inch rod length to achieve a 10.8:1 compression ratio with their -20cc dish volume. This specific compression ratio is often sought after for naturally aspirated or forced induction applications where optimized power output is the goal.

Mahle constructs these pistons from 4032 aluminum alloy, a material known for its strength and durability, especially under high temperatures and pressures. This alloy offers a good balance between expansion characteristics and resistance to detonation, making it a popular choice for performance engine builds. Each piston weighs in at approximately 519 grams, contributing to a well-balanced rotating assembly. The 0.990-inch pin diameter ensures a strong connection to your connecting rods.

This set includes eight pistons, providing everything you need for a complete V8 engine rebuild. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity of your engine.
