Product Details

If you're building a high-performance LSX engine, Mahle's MS Piston set for 428 cubic inches is a solid choice. These pistons are designed for the demands of a serious build, offering a robust foundation for your engine's power. They feature a 4.065-inch bore and are engineered to work with a 4.125-inch stroke and a 6.125-inch connecting rod, creating the 428cid displacement. The -20cc dish volume contributes to a 9.9:1 compression ratio when paired with appropriate cylinder heads and deck height.

Crafted from 2618 aluminum, these pistons are well-built for strength and durability under high stress. Each piston weighs in at 413 grams, contributing to a balanced rotating assembly. The 0.927-inch pin diameter is standard for many performance LS applications. This set includes all eight pistons needed for a V8 engine, ensuring you have what you need to complete your engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal performance and longevity, ensure proper balancing of your rotating assembly and follow manufacturer guidelines for installation and break-in procedures.
