Mahle MS Piston Set GM LSX 441cid 4.125x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 11.7CR Set of 8

Mahle is well-known for making solid engine components, and this piston set for GM LSX engines is no exception. If you're building a high-performance 441 cubic inch LSX engine, these pistons are designed to handle the demands of a serious build. They are specifically made for a 4.125 inch bore and come with a dish volume of -5.8cc, which helps achieve an 11.7:1 compression ratio when paired with the right cylinder heads and gasket combination.

These pistons are forged from 2618 aluminum, a strong material commonly used in performance applications because it can withstand high temperatures and pressures. They feature a 4.125 inch stroke compatibility and are designed to work with a 6.125 inch connecting rod and a .927 inch wrist pin. Each piston weighs in at 439 grams, which is a good balance for strength and rotational mass in a performance engine. This set includes eight pistons, ready for your next engine assembly.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have the correct matching components like crankshaft, connecting rods, and cylinder heads to achieve your desired performance goals.
