Mahle MS Piston Set GM LSX 377cid 4.070x1.330CH 3.622 Stk 6.098 Rod .945 Pin -5.8cc 10.2CR Set of 8

This set includes eight Mahle MS forged pistons, specifically built for GM LSX 377 cubic inch engines. You get pistons with a 4.070-inch bore, a 1.330-inch compression height, and a dish volume of -5.8cc, which results in a 10.2:1 compression ratio when paired with a 6.098-inch connecting rod and a 3.622-inch stroke crankshaft. Each piston weighs in at 469 grams and uses a 0.945-inch wrist pin.

Mahle is known for making well-built engine components, and these pistons are no exception. They are forged from 2618 aluminum, a strong material that can handle the higher stresses and temperatures found in performance applications. This makes them a solid choice if you're rebuilding a performance LSX engine and need pistons that can stand up to demanding use. The specific dimensions are crucial for achieving the desired compression ratio and ensuring proper piston-to-valve clearance, especially when using a stock stroke crankshaft and connecting rod combination.

When installing these pistons, remember they are designed for a specific setup. It's important to verify that your connecting rods and crankshaft stroke match the specifications listed to achieve the intended compression ratio and avoid interference. Also, note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on proper fitment and assembly procedures.
