Product Details

Mahle is a well-known name in engine components, and their MS Piston Set is built for serious performance builds. If you're working on a Ford Small Block engine, specifically the 332 cubic inch variant, these pistons are designed to handle the demands of a high-performance rebuild. They are crafted from 2618 aluminum, a material chosen for its strength and ability to withstand high temperatures and pressures common in performance applications.

This set is engineered for a 4.030-inch bore and features a 3.250-inch stroke with a 5.400-inch rod length. The -6.5cc dish volume, combined with other engine dimensions, results in a compression ratio of 9.6:1, which is a popular target for many naturally aspirated and forced induction builds. Each piston weighs in at 425 grams, contributing to a well-balanced rotating assembly. The 0.927-inch pin diameter is standard for many performance applications.

When rebuilding your engine with these pistons, ensure you follow the manufacturer's recommended clearances and installation procedures. Remember 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 assembly details and compatibility with other engine components.
