Mahle MS Piston Set GM LSX 417cid 4.010x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 11.1CR Set of 8

This Mahle MS Piston Set is designed for GM LSX engines displacing 417 cubic inches. What you get in this set are eight forged pistons, each featuring a 4.010-inch bore, designed to work with a 4.125-inch stroke crankshaft and 6.125-inch connecting rods. The pistons also include a 0.927-inch wrist pin and have a -5.8cc volume, which contributes to an 11.8:1 compression ratio with the specified components. Each piston weighs approximately 407 grams.

These pistons are constructed from 2618 aluminum, a material known for its strength and durability, making them well-suited for demanding engine builds. The 4.010-inch bore size is a common specification for stroker kits aimed at increasing displacement, and these pistons are engineered to accommodate that. The included wrist pins are 0.927 inches in diameter, a standard size for many performance applications. The -5.8cc dish volume is carefully calculated to achieve a specific compression ratio, in this case, 11.8:1 when paired with the correct cylinder heads and crankshaft, offering a notable increase over stock for improved power output.

When building a high-performance engine, the choice of pistons is critical. Mahle is a well-known name in engine components, and this set is built to handle the stresses of increased horsepower and torque. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures to ensure optimal performance and longevity of your engine build.
