Mahle MS PowerPak LS 6.2L 4.075in Bore 3.622 Stroke 6.098 Rod .945 Pin 457g Flat Top Piston Kit

This Mahle MS PowerPak piston kit is built for the Chevrolet LS engine, specifically for the 6.2L displacement, offering a 378 cubic inch displacement. It's designed for builders looking to assemble or rebuild a high-performance LS engine, providing a solid foundation for increased power and durability. The kit includes everything needed to get your pistons installed, making it a convenient choice for engine builders.

Inside this kit, you'll find forged pistons with a 4.075-inch bore and a 3.622-inch stroke, paired with 6.098-inch connecting rods and .945-inch wrist pins. These pistons are a flat-top design with a -5.8cc dish, contributing to a 10.2:1 compression ratio when used with the specified components. The pistons themselves weigh in at 457 grams, a common weight for performance LS pistons, and are constructed from 4032 aluminum, known for its strength and resistance to expansion, which is crucial for tight tolerances and sustained high temperatures. This material choice helps ensure longevity and consistent performance under demanding conditions.

When assembling your engine with this Mahle kit, pay close attention to the specified clearances and assembly procedures. The 4032 aluminum construction allows for tighter piston-to-wall clearances compared to older 2618 aluminum, which can lead to quieter operation and improved ring seal. This kit is a popular choice for those building naturally aspirated or boosted LS engines where reliability and performance are key. Please note that this kit is not CARB approved and cannot be shipped to California. It also carries a California Proposition 65 warning.
