Mahle MS Piston Set SBF 392ci 4.030in Bore 3.85in Stroke 5.956in Rod .912 Pin -26cc 9.1 CR Set of 8

This Mahle MS Piston Set gives you a complete set of eight forged pistons designed for Ford Small Block 393 cubic inch engines. You get pistons with a 4.030-inch bore, a 3.850-inch stroke, and a 5.956-inch rod length, all featuring a 0.912-inch pin diameter. These pistons are crafted from 4032 aluminum and are designed to achieve a 9.1:1 compression ratio with a -26cc volume dish.

Mahle's MS series pistons are built for performance builds where reliability is key. The 4032 aluminum alloy offers a good balance of strength and lighter weight compared to cast pistons, while also providing better thermal expansion properties than older 2618 alloys, which can lead to quieter operation and improved longevity. The dish volume is specifically calculated to work with common crankshaft and head combinations to achieve the target compression ratio, making them a solid choice for engine rebuilds aiming for improved performance without sacrificing everyday drivability.

When rebuilding your engine with these pistons, it's important to note that they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly, including ring gap setting and bearing clearances, to ensure optimal performance and durability for your specific application.
