Mahle MS Piston Set GM LSX 378cid 4.075x1.330CH 3.622 Stk 6.098 Rod .945 Pin -5.8cc 10.2CR Set of 8

If you're rebuilding the heart of your GM LSX engine and aiming for more power, a solid set of pistons is where you start. This Mahle MS Piston Set is built for the 378 cubic inch LSX platform, offering a robust foundation for a high-performance build. Mahle is a well-known name in engine components, and these pistons are designed to handle the demands of a performance engine.

These pistons are forged from 2618 aluminum, a strong material commonly used for performance applications because of its durability and ability to withstand high temperatures and pressures. They feature a 4.075-inch bore and a 1.330-inch compression height, designed to work with a 3.622-inch stroke and a 6.098-inch connecting rod. The dish volume is -5.8cc, which, combined with other engine components, results in a 10.2:1 compression ratio. This compression ratio is a good balance for many performance builds, offering improved power output without being so high that it requires exotic fuel in most setups. Each piston weighs in at 471 grams, contributing to a well-balanced rotating assembly.

This set includes eight pistons, enough for a complete V8 engine. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper assembly and tuning to get the most out of these performance pistons.
