Product Details

If you're building a high-performance LS engine, Mahle's MS Piston Set is a solid choice for your 430 cubic inch application. These pistons are designed to handle the demands of a performance build, offering a robust foundation for your engine's power output. They feature a 4.135-inch bore and a 4.000-inch stroke, working in conjunction with a 6.125-inch rod length to achieve the desired engine displacement and compression ratio.

Crafted from 2618 aluminum, these pistons are well-built for strength and durability under high stress. The flat-top design, combined with a -5.8cc dish, contributes to an 11.4:1 compression ratio when paired with a 4.000-inch stroke and 6.125-inch rod. Each piston weighs in at 454 grams, a common weight for performance applications that balances strength with rotational mass. The 0.927-inch pin diameter is standard for many performance LS applications, ensuring compatibility with a wide range of connecting rods.

This set is intended for custom engine builds where precise control over displacement and compression is key. Please 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 fitment and assembly.
