Mahle MS Piston Set GM LT1 376ci 4.065in Bore 3.622in Stk 6.125in Rod -4cc 11.5 CR Set of 8

When you're rebuilding the top end of your GM LT1 engine, getting the right pistons is crucial. This set from Mahle gives you a complete set of eight forged pistons designed for the 376 cubic inch LT1, L86, and LT4 platforms. They are specifically made to work with GM LT1 and L86 cylinder heads, ensuring a proper fit and function for your build.

These pistons are forged from 2618 aluminum, a strong material commonly used for high-performance applications because it can handle the heat and stress of powerful engines. They feature a -4.5cc dish volume, which helps achieve an 11.6:1 compression ratio when paired with compatible heads, giving you a noticeable bump in power and throttle response. The pistons have a 4.065-inch bore, a 3.622-inch stroke, and are designed to work with a 6.125-inch connecting rod, with a compression height of 1.304 inches. Each piston weighs in at 481 grams, keeping rotating assembly weight manageable for improved engine response.

This set includes everything you need to replace all eight pistons in your engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
