Mahle MS Piston Set GM LSX 454cid 4.185x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 12.0CR Set of 8

When you're building a serious performance engine, especially a GM LSX 454 cubic inch application, the pistons are a critical component. This set from Mahle includes eight forged pistons, designed to handle the demands of a high-compression, high-horsepower build. You get the pistons themselves, ready to be installed into your engine block.

These pistons are forged from 2618 aluminum, a strong material commonly used in performance applications because it can withstand high temperatures and pressures. They feature a 4.185-inch bore size, a -5.8cc dish volume, and are designed to achieve a 12.0:1 compression ratio when paired with a 4.125-inch stroke crankshaft and a 6.125-inch connecting rod. The pin diameter is 0.927 inches, and the compression height is 1.050 inches. Each piston weighs in at approximately 462 grams, which is a reasonable weight for a forged piston of this size and strength.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for proper fitment and assembly, especially when dealing with critical engine components like pistons. Ensure you have the correct connecting rods, crankshaft, and cylinder heads to achieve the intended compression ratio and performance goals for your LSX engine.
