Mahle MS Pistons LSX 415cid 4.0in Bore 4.125in Stk 6.125in Rod .927 Pin -20cc Dish 9.6CR Set of 8

If you're building a high-performance LS engine for serious power, a strong set of pistons is where it all starts. These Mahle MS pistons are designed for LSX applications, specifically for a 415 cubic inch displacement with a 4.0-inch bore and a 4.125-inch stroke. They're built to handle the demands of a performance build, ensuring reliable operation when you're pushing the limits.

Crafted from 2618 aluminum, these pistons are well-built for strength and durability under high cylinder pressures. The -20cc dish volume contributes to a 9.6:1 compression ratio when paired with a 6.125-inch rod and the specified bore and stroke, making them suitable for naturally aspirated or forced induction setups where controlled compression is key. The 0.927-inch pin diameter is standard for many performance LS applications, and at 388 grams each, they offer a good balance of strength and weight for their class.

This set includes eight pistons, ready to be installed in your LSX engine. Please note 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.
