Mahle MS Piston Set Chevy 376ci 4.065x1.304CH 3.622 Stroke 6.125 Rod 0.927 Pin -12.0cc 456g 9.5CR

Mahle is well-known for making high-performance engine components, and this forged piston set is a prime example of their work for Chevy LS engines. If you're building a 376 cubic inch LS motor and need pistons that can handle serious power, these are a solid choice. They're designed with a 4.065-inch bore and a 3.622-inch stroke, working with a 6.125-inch connecting rod and a 0.927-inch wrist pin. The -12.0cc dish volume helps achieve a 9.5:1 compression ratio with the right cylinder heads, making them suitable for naturally aspirated or forced induction applications where reliable performance is key.

These pistons are forged from 2618 aluminum, a material chosen for its strength and durability under high stress and temperature. Each piston weighs in at 456 grams, which is a good balance for performance and reliability in a stroker engine. The 1.304-inch compression height is specific to the combination of the 3.622-inch stroke and 6.125-inch rod length, ensuring proper piston-to-valve clearance and deck height. Mahle's attention to detail in their forging process means you get a well-built piston that's ready for the demands of a performance build.

When installing these pistons, remember they are designed for specific engine configurations. It's important to verify all measurements, including deck height and compression ratio, with your chosen cylinder heads and crankshaft to ensure optimal engine operation. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guidelines for the best results.
