Mahle MS Chevrolet LS 6.8L 408cid 4.030in Bore x 1.110RCH 4.000 Stroke 9.2cc 13.8CR - Pist Set of 8

If you're building a high-performance Chevrolet LS engine for serious power, a strong set of pistons is where it all starts. This Mahle MS piston set is built for the demanding LSX 408 cubic inch platform, giving you a solid foundation for a custom build.

These pistons are forged from 2618 aluminum, a material known for its strength and ability to handle high temperatures and pressures. They feature a 4.030-inch bore and a 4.000-inch stroke, designed to work with a 6.125-inch rod and a 0.927-inch pin. With a 9.2cc dish volume, they achieve a 13.8:1 compression ratio, which is ideal for naturally aspirated or forced induction setups where maximum power is the goal. Each piston weighs in at 465 grams, balancing strength with reasonable reciprocating mass for the application.

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. Always consult your engine builder or Mahle's technical documentation for specific assembly and tuning recommendations to get the most out of this high-performance component.
