Mahle MS Chevrolet LS 5.3L 363cid 3.800in Bore x 1.110RCH 4.000 Stroke 2.0cc 11.6 CR - Pist Set of 8

If you're building a performance LS engine for your Chevrolet, especially one aiming for increased displacement and compression, a solid set of forged pistons is where you start. This Mahle MS piston set is built for LS 5.3L engines, specifically designed to work with LS1/2/6 style cathedral port heads. They're engineered to handle the demands of a performance build, offering a robust foundation for your engine's power output.

These pistons are forged from 2618 aluminum, a material known for its strength and durability under high stress and temperature. This set features a 3.800-inch bore and a 4.000-inch stroke, bringing the displacement to 363 cubic inches. The dome design and 2.0cc volume, combined with a 11.6:1 compression ratio, are tailored for optimal performance when paired with cathedral port heads. Each piston weighs 402 grams, contributing to a well-balanced rotating assembly. The 0.927-inch pin size is standard for many LS applications.

This set includes pistons for a complete 8-cylinder engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Mahle's technical documentation for specific assembly details and compatibility with other engine components to ensure a successful build.
