This is a set of eight Mahle forged pistons designed for LS engines. You get the pistons themselves, ready to be installed in your 378 cubic inch build. These pistons feature a -4.5cc dish volume, which helps achieve a 10.0:1 compression ratio when paired with compatible LS heads, making them a solid choice for a performance-oriented engine rebuild.

Mahle has engineered these pistons with a 4.075-inch bore and a 3.622-inch stroke, utilizing a 6.125-inch connecting rod. The pin diameter is 0.927 inches, and each piston weighs in at 483 grams. The 2618 aluminum alloy construction is well-known for its strength and durability under high stress, which is crucial for boosted or high-performance naturally aspirated LS applications. These are designed to work with all LS heads, offering broad compatibility for your project.

When rebuilding or upgrading your LS engine, choosing the right pistons is key to achieving your desired performance and reliability. These Mahle pistons are a well-built option for those looking to build a 378 cubic inch engine with a specific compression target.
