Mahle MS Piston Set GM LSX 418cid 4.080x1.110RCH 4.0 Stk 6.125 Rod .927 Pin -14cc 10.3CR - Set of 8

If you're building a high-performance GM LSX engine for serious power, a solid set of pistons is where it all starts. This Mahle MS Piston Set is designed for 418 cubic inch LSX applications, giving you the foundation for a robust and powerful engine build. Mahle is a well-known name in engine components, and these pistons are crafted to handle the demands of a performance engine.

These pistons are forged from 2618 aluminum, a strong material commonly used for high-performance pistons because it can withstand high temperatures and pressures. They feature a 4.080-inch bore and a -14cc dish volume, which contributes to a 10.3:1 compression ratio when paired with a 4.000-inch stroke and a 6.125-inch connecting rod. The 0.927-inch pin diameter is standard for many performance LS applications. Each piston weighs in at 429 grams, keeping rotating assembly weight manageable for improved engine response.

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 achieve the best results from your new Mahle pistons.
