What is the compression ratio with these pistons?

These Mahle pistons have a -4.5cc dish volume. When used with appropriate cylinder heads and gasket combinations for a 302ci engine, they achieve a 10.1:1 compression ratio.

Are these pistons suitable for a stock engine rebuild?

These are forged pistons designed for performance applications and higher compression. While they can be used in a rebuild, they are best suited for builds aiming for improved performance and durability beyond stock specifications.

What does 'Not CARB approved' mean for shipping?

This means the pistons do not meet California Air Resources Board emissions standards. Consequently, they cannot be legally shipped to California addresses.

Product Details

If you're rebuilding the heart of your Ford 5.0L Modular Coyote or Voodoo engine, a solid set of pistons is crucial. This Mahle MS Piston Set is built for 302 cubic inch displacements, featuring a 3.630-inch bore and a 3.650-inch stroke, designed to work with a 5.933-inch rod and a 0.866-inch pin. These pistons are forged, which means they're incredibly strong and can handle the higher stresses of performance builds.

Mahle has engineered these pistons with a -4.5cc dish volume, resulting in a 10.1:1 compression ratio when paired with the right components. This compression level is a notable step up from stock, offering a good balance for street performance and track use without being overly aggressive. The pistons themselves weigh in at 383 grams, contributing to a well-balanced rotating assembly. They are well-built to withstand the demands of a performance engine, ensuring reliability for your project.

This set includes pistons for all 8 cylinders. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, especially regarding ring gap, piston-to-wall clearance, and bearing clearances.
