Mahle MS Piston Set SBF 410ci 4.040in Bore 4.000in Stroke 6.2in Rod .927 Pin -20cc 10.2 CR Set of 8

This Mahle MS Piston Set gives you everything you need to rebuild the heart of your Ford Small Block engine for a 410 cubic inch displacement. You get a complete set of eight forged pistons, designed to work with a 4.000 inch stroke crankshaft and a 6.200 inch connecting rod. Each piston features a 4.040 inch bore and a .927 inch pin diameter, with a -20cc dish that helps achieve a 10.2:1 compression ratio.

Mahle uses 4032 aluminum for these pistons, a well-known material for its strength and durability, especially in high-performance applications. This alloy offers good thermal expansion properties, which is crucial for maintaining proper clearances as the engine heats up. The pistons are forged, meaning they start as a solid piece of aluminum that's heated and hammered into shape, creating a stronger, more resilient component than cast pistons. At 422 grams each, they offer a solid balance of strength and weight for a 410ci build.

This set is intended for performance builds where a specific compression ratio and displacement are targeted. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Ensure you have the correct supporting components, such as cylinder heads, camshaft, and crankshaft, to match the intended compression ratio and performance goals of your engine build.
