Mahle MS Piston Set GM LSX 416cid 4.005x1.050RCH 4.125 Stk 6.125 Rod .927 Pin -5.8cc 11.1CR Set of 8

Mahle is well-known for making solid engine components, and this MS Piston Set is a great example of their work for GM LSX engines. If you're building a 416 cubic inch LSX, these pistons are designed to handle the demands of a performance build. They feature a 4.005-inch bore, which is the standard bore size for a 416 cubic inch LSX engine, and are paired with a 4.125-inch stroke and a 6.125-inch rod length. This combination is key for achieving the correct displacement and performance characteristics.

These pistons are forged from 2618 aluminum, a strong material commonly used in high-performance applications because of its durability and resistance to expansion under heat. They have a dish volume of -5.8cc, which, when combined with the other engine specifications, results in a compression ratio of 11.1:1. This compression ratio is suitable for many naturally aspirated and forced induction setups, offering a good balance between power and pump gas compatibility. The pistons also include a 0.927-inch pin diameter, which is standard for many LS applications, and come in at a weight of 405 grams, contributing to a well-balanced rotating assembly.

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 the manufacturer's installation instructions for proper fitment and assembly procedures, especially when dealing with critical engine components like pistons.
