Mahle MS Piston Set SBC 358ci 4.03in Bore 3.500in Stroke 6.0in Rod .927in Pin -4cc 10.5 CR Set of 8

Mahle's MS Piston Set is built for serious performance builds, specifically targeting the Chevrolet Small Block engine. These pistons are forged from 4032 aluminum, a material known for its strength and durability under high stress, making them a solid choice for engines aiming for around 10.5:1 compression ratio. The set is designed for a 4.030-inch bore and a 3.500-inch stroke, with a 6.0-inch connecting rod and a 0.927-inch wrist pin, all contributing to a precise fit and optimal performance within a 358 cubic inch displacement.

Each piston in this set features a -4.1cc dish volume, which helps achieve that 10.5:1 compression ratio when paired with the correct cylinder heads and gasket combination. Weighing in at 393 grams, these pistons offer a good balance of strength and weight, crucial for high-RPM operation. The 4032 aluminum construction provides excellent thermal expansion characteristics, reducing the risk of piston slap and improving overall engine longevity, especially in demanding applications. This set includes eight pistons, ready for your next engine build.

It's important to note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation guidelines to ensure proper fitment and performance for your specific engine build.
