What is the compression ratio achieved with these pistons?

These Mahle MS pistons feature a -7.4cc dish volume. When used with the specified stroke and rod length, they are designed to achieve an 11.3:1 compression ratio.

What material are these pistons made from?

The pistons are constructed from 4032 aluminum alloy. This material is chosen for its balance of strength and thermal expansion properties, making it suitable for performance engine builds.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This is a set of eight Mahle MS forged pistons, designed for SBF 444 cubic inch engines. You get pistons with a 4.080-inch bore, a 4.250-inch stroke, and a 6.700-inch rod length. Each piston features a 0.990-inch pin diameter and a -7.4cc dish volume, which helps achieve an 11.3:1 compression ratio with the specified components. These pistons are made from 4032 aluminum and weigh in at approximately 473 grams each.

Mahle is a well-known name in engine components, and these pistons are built for performance applications. The 4032 aluminum alloy is a good choice for high-stress engine builds because it offers a strong balance of durability and thermal expansion properties, which is important for maintaining proper piston-to-wall clearance as the engine heats up. The dish volume is specifically calculated to work with a 4.250-inch stroke and a 6.700-inch rod to achieve that 11.3 compression ratio, making them a solid option for a performance-oriented SBF build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for performance engine builds where specific compression ratios and component matching are critical. Always refer to Mahle's installation guidelines for proper fitment and assembly procedures.
