Mahle MS Piston Set SBF 408ci 4.030in Bore 4.000in Stroke 6.0in Rod .927 Pin -3cc 12.0 CR Set of 8

When you're building a serious performance engine, the pistons are the heart of the operation. What you get in this Mahle MS Piston Set are eight forged pistons designed for a Ford Cleveland 408 cubic inch engine. These pistons are built to handle the demands of a high-performance build, featuring a 4.030-inch bore and a 4.000-inch stroke, paired with a 6.0-inch connecting rod and a .927-inch pin. Each piston weighs in at 453 grams and has a -3.2cc dish volume, which contributes to a 12.1 compression ratio when used with the right cylinder heads and gasket combination.

Mahle uses 4032 aluminum alloy for these pistons, a material known for its strength and durability, especially under high temperatures and pressures. This alloy offers a good balance between expansion characteristics and wear resistance, making it a solid choice for performance street or track applications. The forged construction means these pistons are significantly stronger than cast pistons, able to withstand higher cylinder pressures and detonation events without failing. This set is engineered for performance builds where reliability and power are key considerations.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a successful installation, ensure you have the correct connecting rods, wrist pins, and piston rings that match the specifications. Proper balancing of the rotating assembly is also crucial for engine longevity and smooth operation. This set is a critical component for anyone looking to maximize the performance of their Ford Cleveland engine.
