If you're rebuilding the engine in your Chevrolet LS 5.3L, this set of Mahle MS forged pistons is a solid choice. These pistons are built for the 325 cubic inch displacement and are designed to work with LS1, LS2, and LS6 style cathedral port heads. They feature a 3.780-inch bore and a 3.622-inch stroke, with a 1.299-inch compression height. The 14.0cc dome volume contributes to a 12.4:1 compression ratio, which is a notable increase over stock and can help you get more power out of your engine.

Mahle uses 2618 aluminum for these pistons, a material known for its strength and durability under high stress, making them well-suited for performance applications. Each piston weighs in at 450 grams and includes a 0.927-inch pin. This set comes with all eight pistons needed for a complete engine rebuild. Remember 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.
