Mahle MS Piston Set GM LSX 428cid 4.125x1.110RCH 4.0 Stk 6.125 Rod .927 Pin 5.6cc 13.7CR - Set of 8

If you're building a high-performance GM LSX engine, a solid set of pistons is crucial for handling the increased power and stress. This Mahle MS Piston Set is designed for 428 cubic inch LSX applications, offering a robust foundation for your build. Mahle is a well-known name in engine components, and these pistons are built to meet the demands of a performance engine.

This set features a 4.125-inch bore and is designed to work with a 4.000-inch stroke and a 6.125-inch connecting rod. The piston pin diameter is 0.927 inches, a common size for performance builds. With a 5.6cc dish volume, these pistons achieve a 13.0:1 compression ratio when paired with the right cylinder heads, which is ideal for naturally aspirated or forced induction setups looking for significant power gains. Each piston weighs in at 482 grams, contributing to a balanced rotating assembly. The 2618 aluminum alloy construction offers good strength and thermal properties for performance use.

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. It's always recommended to consult with your engine builder or refer to Mahle's technical documentation for specific installation details and compatibility with other engine components to ensure optimal performance and longevity.
