Designed for high-performance Chevrolet LS engines, the Mahle MS Pistons set is engineered to deliver exceptional power and durability. These pistons are tailored for a 428 cubic inch displacement with a bore diameter of 4.065 inches, providing precise fitment and optimal combustion efficiency. The 4.125-inch stroke and 6.125-inch connecting rods contribute to a robust engine build, ideal for racing or high-performance street applications. Constructed with a dish design of 20cc, these pistons help achieve a compression ratio of approximately 9.9:1, balancing power output with reliability. The pistons feature a phosphate and Grafal coating, enhancing wear resistance and reducing friction, which extends engine life under demanding conditions.
