Mahle MS Piston Set GM LT1 377ci 4.07in Bore 3.622in Stk 6.125in Rod .927 Pin -4cc 11.6 CR Set of 8

What you get in this Mahle MS Piston Set are eight forged pistons designed for GM LT1, L86, and LT4 engines. These pistons are built to handle the demands of a 377 cubic inch displacement, featuring a 4.070-inch bore and a 3.622-inch stroke. They're engineered to work with LT heads and come with a 0.927-inch pin, a -4.5cc dish volume, and are designed for an 11.6:1 compression ratio when paired with the correct components.

These pistons are forged from 2618 aluminum, a strong material commonly used for high-performance applications because it can withstand the heat and pressure of powerful engines. Each piston weighs in at 483 grams, which is a notable detail for engine builders balancing rotating assembly components. The 6.125-inch rod length specification is also important for ensuring proper geometry within the engine block. Mahle is a well-known name in engine components, and this set is a solid option for anyone rebuilding or upgrading their GM LT engine.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance LT engine, these pistons offer a strong foundation. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
