Mahle MS Chevrolet LS 5.3L Piston Set 327cid 3.790in Bore 3.622 Stroke 8.5cc 11.5 CR Set of 8

This is a Mahle MS Piston Set designed for Chevrolet LS 5.3L engines, specifically for builds using a 327 cubic inch displacement. These pistons are built to work with LS1/2/6 style cathedral port cylinder heads, making them a solid choice for a performance engine rebuild.

Each piston in this set has a 3.790-inch bore and is designed with an 8.5cc dome volume, contributing to an 11.5:1 compression ratio. This higher compression ratio is key for extracting more power from your engine, especially when paired with compatible heads. The pistons are constructed from 2618 aluminum, a material known for its strength and durability under high stress, which is crucial for performance applications. They feature a 3.622-inch stroke compatibility, a 6.098-inch rod length, and a 0.945-inch pin diameter, all precisely machined for a proper fit and function within the engine. Each piston weighs in at 445 grams, indicating a well-built component designed for performance.

This set includes eight pistons, enough for a complete V8 engine. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to manufacturer installation instructions for proper fitment and assembly procedures.
