Mahle MS Piston Set GM LSX 440cid 4.185x1.110RCH 4.0 Stk 6.125 Rod .927 Pin 5.6cc 14.0CR - Set of 8

If you're building a high-performance GM LSX engine, this Mahle MS Piston Set is designed for serious power. These pistons are specifically made for the 440 cubic inch displacement, featuring a 4.185-inch bore and a 1.110-inch compression height, which works with a 4.000-inch stroke and a 6.125-inch rod. The 0.927-inch pin diameter is standard for many performance applications.

Mahle uses 2618 aluminum for these pistons, a strong material known for its durability under high stress and heat, which is crucial for boosted or high-compression builds. The 5.6cc dish volume contributes to a 14.0:1 compression ratio when paired with the right cylinder heads and gasket, giving you a significant power increase. Each piston weighs approximately 506 grams, balancing strength with reasonable reciprocating mass for the engine's internals.

This set includes eight pistons, all the necessary hardware like pins and locks, ready for installation. Keep in mind 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, especially when dealing with high-compression builds.
