If you're rebuilding the heart of your Chevrolet LS 345 cubic inch engine, this Mahle MS Piston Set is a solid choice for serious performance. Mahle is a well-known name in engine components, and this set is built for demanding applications where reliability and power are key. These pistons are designed to handle the stresses of higher compression and more aggressive engine builds.

This set includes eight forged pistons, each weighing 406 grams, with a 3.898-inch bore and a 3.622-inch stroke. They feature a -4.1cc dish volume, which contributes to a 10.1:1 compression ratio when paired with the correct components. The 6.125-inch rod length and 0.927-inch pin diameter are standard for many LS applications, ensuring good compatibility. The use of 4032 aluminum alloy means these pistons are well-built to withstand high temperatures and pressures, offering improved durability over cast pistons for performance builds.

When installing these pistons, remember they are designed for specific LS engine configurations. It's crucial to ensure your crankshaft, connecting rods, and cylinder heads are compatible to achieve the intended compression ratio and performance. Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper fitment and assembly procedures.
