Mahle MS Piston Set SBC 358ci 4.04in Bore 3.48/3.5stk 6.0in Rod .927 Pin 11cc 12.9 CR Set of 8

Mahle is a well-known name in engine components, particularly for their expertise in pistons and rings. This Mahle MS Piston Set is built for serious performance applications, specifically for Chevrolet Small Block engines displacing around 357 cubic inches. If you're building a high-compression, high-performance engine, these pistons are designed to handle the demands.

These are forged pistons, meaning they start as a solid block of aluminum that's heated and forced into shape under extreme pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for engines that will see heavy use or high boost. This set features a 4.040-inch bore, designed to work with a 3.480 or 3.500-inch stroke crankshaft and a 6.000-inch connecting rod. The compression height is 1.250 inches, and they use a standard 0.927-inch wrist pin. With an 11.1cc dish volume, these pistons achieve a 12.9:1 compression ratio when paired with the right cylinder heads and gasket combination, making them suitable for naturally aspirated or forced induction builds aiming for significant power.

Each piston in this set weighs approximately 488 grams, which is a good balance of strength and weight for performance applications. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They also come with a Prop 65 warning. This set includes eight pistons, ready for your next engine build.
