Mahle MS Chevy LS1/2/6 3.800in Bore / 6.622in Stoke / 6.098in Rod Length - Pistons (Set Of 8)

Forged from 2618 aluminum alloy, these Mahle MS pistons are built for serious performance in Chevy LS1, LS2, and LS6 engines. They feature a 3.800-inch bore and are designed to work with a 6.622-inch stroke and a 6.098-inch rod length, creating a 329 cubic inch displacement. The -4.2cc dish volume contributes to a 9.8:1 compression ratio when paired with a suitable cylinder head, making them a solid choice for naturally aspirated or forced induction builds where controlled compression is key.

Each piston weighs in at 428 grams, a balance that helps manage reciprocating mass without sacrificing strength. The 0.945-inch pin diameter is standard for many performance LS applications, ensuring good compatibility with aftermarket connecting rods. Mahle's reputation for well-built engine components means you're getting a set designed for durability and consistent performance under demanding conditions. These are not CARB approved and cannot be shipped to California.
