Mahle MS Piston Set GM LSX 379cid 4.080x1.330CH 3.622 Stk 6.098 Rod .945 Pin -5.8cc 10.2CR Set of 8

When you're rebuilding the heart of your GM LSX engine, especially for a 379 cubic inch displacement, selecting the right pistons is crucial for both power and reliability. This Mahle MS Piston Set is built for those who demand solid performance from their engine build. These pistons are designed to work with a 4.080-inch bore and feature a 1.330-inch compression height, which is key for achieving the correct valve timing and piston-to-valve clearance with your specific camshaft and cylinder head combination.

Crafted from durable 2618 aluminum, these pistons are well-built to handle the stresses of a performance engine. They come with a dish volume of -5.8cc, contributing to a 10.2:1 compression ratio when paired with appropriate cylinder heads and a 3.622-inch stroke crankshaft. The included 0.945-inch wrist pins are a standard size for many performance LS applications, and the 6.098-inch connecting rod length is also specified for this setup. Each piston weighs in at 473 grams, which is a good balance for strength and rotational mass in a performance build.

This set includes all eight pistons needed for a complete engine rebuild. 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 and ensure all related components, such as rings and bearings, are compatible and properly installed for optimal engine performance and longevity.
