Product Details

Mahle is well-known for making high-performance engine components, and this MS PowerPak piston kit for the LS 6.2L engine is a prime example of their expertise. If you're building or rebuilding a 377 cubic inch LS engine, this kit gives you the core components to get your short block assembled. These pistons are designed for a 4.070-inch bore and feature a 3.622-inch stroke, working with a 6.098-inch connecting rod and a .945-inch wrist pin.

This kit includes flat-top pistons with a -5.8cc dish volume, which results in a 10.2:1 compression ratio when paired with the correct cylinder heads and gasket combination. They are constructed from 4032 aluminum, a material chosen for its strength and thermal expansion properties, making it suitable for demanding applications. The pistons weigh in at 455 grams, contributing to a well-balanced rotating assembly. This is a forged piston set, meaning it's built from a solid block of aluminum that's heated and hammered into shape, giving it superior strength and durability compared to cast pistons.

This Mahle MS PowerPak kit is a solid option for anyone looking to build a powerful and reliable LS engine. Please note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
