Product Details

Mahle is a well-known name in engine components, and they're especially recognized for their piston technology. This set of 8 forged pistons is built for Ford Modular engines, specifically the 285 cubic inch displacement versions found in 2-valve and 4-valve applications. If you're rebuilding the heart of your Ford, these pistons are a solid choice for performance and durability.

These pistons feature a 3.581-inch bore and a -16cc dish volume, which helps achieve a 9.5:1 compression ratio when paired with the correct components. The stroke is 3.543 inches, and they're designed to work with a 5.933-inch connecting rod and a 0.866-inch wrist pin. Each piston weighs in at 367 grams, a common weight for this type of performance component. The forged construction means they are strong and can handle higher cylinder pressures compared to cast pistons, making them suitable for builds that demand more from the engine.

This set includes all 8 pistons needed for a V8 engine. 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.
